Log Message:
Update xmlrpc-c to new "super stable" version 1.51.04.

Pkgsrc changes:
 * Renamed patches to follow new pkgsrc conventions.
 * Oddly, the .tgz distfile isn't actually compressed.  Compensate.

Upstream changes:

Release 1.51
============

Released 17.12.26.

Subversion directory release_number/10.51.00.

 * Build: Add --disable-abyss-openssl for build environments that
   appear to have Openssl but don't really. (A Pkg-config design
   flaw makes that happen sometimes - you can't control what
   directories it searches for .pc files).
 * Windows build: add Visual Studio 2017 project files, fix various
   things broken for Windows in recent updates. Thanks to Maksym
   Veremeyenko.

Release 1.50
============

Released 17.09.28.

Subversion directory release_number/10.50.00.

 * Build: fix installation of programs. Introduced in Xmlrpc-c
   1.47 (September 2016).
 * Windows build: fix ChanSwitchUnixGetListenName not found.
 * Windows build: Add current VS2010express project files.
 * Windows build: various fixes. Doesn't necessarily work yet.

Release 1.49
============

Released 17.03.26.

Subversion directory release_number/10.49.00.

 * Add program xmlrpc_dumpserver.

Release 1.48
============

Released 16.12.27.

Subversion directory release_number/10.48.00.

 * Disable 10M restriction on document size in Libxml2 XML parser.
 * Build: Recognize additional Linux "host OS" environments. E.g.
   "linux-uclibc".
 * Build: replace BUILDTOOL_CC and BUILDTOOL_CCLD with more
   conventional CC_FOR_BUILD. Add CFLAGS_FOR_BUILD, LDFLAGS_FOR_BUILD.
 * Build: Don't attempt to build C++ internal utility module
   cmdline_parser_cpp if we aren't building the C++ libraries. In
   that case, 1) it isn't needed, and 2) the environment probably
   is incapable of compiling C++.
 * Build: Use AC_CHECK_TOOL to determine 'ar' command and
   AC_PROG_RANLIB to determine 'ranlib' command to use.
 * Build: fix compile failure in build for a system that does not
   have Unicode wide characters (wchar_t).

Release 1.47
============

Released 16.09.25.

Subversion directory release_number/10.47.00.

 * Install: fix bug: xmlrpc_expat.pc not installed.
 * Install: Add 'uninstall' make target

Release 1.46
============

Released 16.06.29.

Subversion directory release_number/01.46.00.

 * Packet stream client: Add option to throw a BrokenConnEx
   exception when transport fails because the server hung up or
   network broke, instead of throwing error.
 * Add ServerAbyss::getListenName method, ChanSwitchUnixGetListeName:
   ability to find out on what port your server is listening.
 * Packet stream server ('serverPstreamConn'): fix bug: runOnce()
   fails with indication that it was interrupted when the server
   hangs up. Always broken (interruptible RunOnce() was new in
   Xmlrpc-c 1.14 (March 2008).
 * Fix compile failure with old OpenSSL that doesn't have
   SSL_ERROR_WANT_ACCEPT. Introduced in Xmlrpc-c 1.45.

Release 1.45
============

Released 16.03.27.

Subversion directory release_number/01.45.00.

 * Add SSL/TLS capability via OpenSSL to Abyss server.
 * Fix xmlrpc_mem_block accidentally made private in 1.44.
 * Build: Remove example and test program usage of XML parser
   facility (<xmlrpc-c/xmlparser.h>), which was made private in
   1.44, so the examples and tools no longer build.

Release 1.44
============

Released 15.12.31.

Subversion directory release_number/01.44.00.

 *  C++: Add 'toValue' and 'fromValue' for 64-bit integer
    (xmlrpc_c::value_i8).
 *  Memory block utility: Remove xmlrpc_mem_block_init and
    xmlrpc_mem_block_clean. These complicate forward compatibility
    and probably were never used. xmlrpc_mem_block_new and
    xmlrpc_mem_block_free remain to fulfill the same purpose.
 *  Remove XML parser (<xmlrpc-c/xmlparser.h>) from external API.
    This is not specific to XML-RPC, so has no business being a
    service of Xmlrpc-c. It is just an abstraction to allow us to
    use various XML parsing libraries (to wit, Expat and Libxml2).
    We don't think it was ever used externally.
 *  Build: make install does not create empty man page directory.

Release 1.43
============

Released 15.09.27.

Subversion directory release_number/01.43.00.

 * Add xmlrpc_value_new(): deep copy of xmlrpc_value.
 * Abyss C++: Add 'terminate' and 'resetTerminate' methods,
   analogous to C Abyss 'ServerTerminate' and 'ServerResetTerminate'.
 * Fix bug: infinite recursion if you try to format a floating
   point value that was created from something other than a finite
   number. Creation of a floating point XML-RPC value from something
   other than a number now fails. Introduced in Xmlrpc-c 1.15
   (June 2008).
 * Curl client: fix garbage in message where explanation from Curl
   library belongs. Always there, with some Curl libraries.
 * Curl client: fix instantaneous timeout with some Curl libraries.
   Introduced in Xmlrpc-c 1.41 (March 2015).
 * Curl client: fix 'connect_timeout' transport parameter interpreted
   as 'timeout'. Always broken ('connect_timeout' was new in
   Xmlrpc-c 1.41 (March 2015)).

Release 1.42
============

Released 15.06.28.

Subversion directory release_number/01.42.00.

 * AbysssServer: add 'Session::headerValue' and 'Session::getHeaderValue'.
 * Fix crash in 'xmlrpc' program under most circumstances. Broken
   in Xmlrpc-c 1.40 (December 2014).
 * Packet socket: fix missing parenthesis in error message. Broken
   in Xmlrpc-c 1.25 (December 2010).

Release 1.41
============

Released 15.03.26.

Subversion directory release_number/01.41.00.

 * Fix crash: multithreaded client program that uses the Curl XML
   transport and does not specify a Curl timeout transport parameter
   crashes because of signal use inside the Curl library, unless
   the Curl library is one that does DNS lookups with the ARES
   library.
 * Make a client that uses the Curl XML transport and does not
   specify a Curl timeout transport parameter wait indefinitely
   for a DNS lookup, or at least until the OS DNS lookup service
   gives up, unless the Curl library is one that does DNS lookups
   with the ARES library. In previous releases, the RPC failed
   after waiting 5 minutes. This was not intended as an enhancement,
   but rather is a side effect of fixing the crash described above.
   But it also adds consistency, since the wait for the DNS lookup
   was always indefinite, ironically, in the case that the program
   specified timeout.
 * Add connect_timeout curl transport parameter.
 * Packet stream socket: fix: sends corrupted packet when the
   packet contains an ESC character. Always broken. (packet stream
   sockets were new in Xmlrpc-c 1.11 - June 2007).
 * Add XMLRPC_TRACE_PACKETSOCKET environment variable: a means of
   tracing communication at the packet socket level.
 * Build: Use -pthread on compile and link instead of just linking
   libpthread if compiler is GNU.
 * Build: Don't rely on <features.h> to define __BEGIN_DECLS
 * Build: don't ignore LDFLAGS in build of Gennmtab. Broken since
   Xmlrpc-c 1.32 (September 2012).
 * Many changes to accomodate Mingw. May not work completely yet.
 * Build: fix a "recompile with -fPIC" failure in parallel make.
 * Build: fix failure with configure --disable-abyss-threads.
   Introduced in Xmlrpc-c 1.38 (March 2014).

Release 1.40
============

Released 14.12.28.

Subversion directory release_number/01.40.00.

 * Fix AbyssServer::readRequestBody for chunked bodies. Always
   broken (AbyssServer was new in Netpbm 1.39 (September 2014).
 * Add pkg-config files (e.g. xmlrpc.pc)
 * Build: fix 'make distclean' so it doesn't leave src/cpp/srcdir
   and src/cpp/blddir.

Release 1.39
============

Released 14.09.27.

Subversion directory release_number/01.39.00.

 * Add C++ Abyss server classes. Not documented yet.
 * Abyss: with access control, send Access-Control-Allow-Headers
   headers for Content-Type and Content-Length.
 * Curl client: Fix bogus "please call curl_muti_perform()" error
   with very old Curl library.
 * Abyss: fix bug: RequestAuth() always says not authenticated.
   Broken in 1.10 (March 2007).
 * Abyss: fix missing prototype for RequestAuth(). Always broken.
 * Install: fix bug: <xmlrpc-c/base64.hpp> not installed.

Release 1.38
============

Released 14.03.25.

Subversion directory release_number/01.38.00.

 * Fix bug: When serializing a very large floating point number,
   sender of an XML-RPC message adds some junk after the decimal
   point. With assertion checking enabled, it just crashes. Broken
   in 1.15 (June 2008).
 * xmlrpc program: add ability to specify a struct or array RPC
   parameter (struct/ and array/).
 * Abyss: fix parsing of URI with %HH escape sequence - always
   said invalid URI. Broken in 1.31 (June 2012).
 * Abyss: Fail ServerRun() and ServerRunOnce() if user hasn't done
   ServerInit() instead of trying to make the channel switch accept
   a connection even though it isn't in listening state. Combined
   with the two problems below, this caused POSIX socket servers
   to go into an infinite loop if the user called ServerRun()
   without a prior ServerInit().
 * Abyss: Fail ChanSwitchAccept() if user hasn't done ChanSwitchListen()
   instead of trying to make the OS do the accept.
 * Abyss: Unix socket: Fix bug: POLLHUP and POLLERR state on
   listening or interrupt socket caused accept function to return
   as if the wait had simply been interrupted.
 * Abyss: fix error HTTP response for invalid request line - showed
   wrong request line. Always broken. (The request line in that
   message was new in Xmlrpc-c 1.19 (June 2009).
 * Abyss: add details to invalid request line error HTTP response.
 * xmlrpc-c-config: add "abyss" target to get just the Abyss
   library - no XML-RPC stuff.

Release 1.37
============

Released 13.12.31.

Subversion directory release_number/01.37.00.

 * Abyss server: Fix bug: reported HTTP status 408 (Request timed
   out) for all problems getting the request from the client. Also
   add text detail of problems getting the request from the client
   to the HTTP error response.
 * Fix pervasive wild pointer dereference when memory allocation
   of small string fails. Introduced in 1.01 (January 2005).
 * Fixes for Windows build problems introduced in 1.33.

Release 1.36
============

Released 13.09.29.

Subversion directory release_number/01.36.00.

 *  C++ server: add versions of 'xmlrpc_c::registry::addMethod'
    that takes a simple pointer to the method object, so you can
    use it with automatic and static method objects. Same for
    'xmlrpc_c::registry::setDefaultMethod'.
 *  Remove 128M limit on certain memory allocations.
 *  Change strategy for overallocating memory - grow blocks no more
    than a megabyte at a time; shrink blocks sometimes.
 *  Fix interpretation of dateTime.iso8601 variant with timezone
    information. As broken, it would add up to a second to the
    correct datetime or reject the message claiming that it has
    invalid syntax. Always broken (recognition of the timezone
    variant was introduced in Xmlrpc-c 1.20 (September 2009).
 *  'xmlrpc', 'xmlrpc_pstream', 'xmlrpc_parsecall': add ability to
    display dateTime.iso8601.
 *  AIX build: various fixes.
 *  Windows build: fix reference to _snprintf; broke in Xmlrpc-c 1.34.
 *  Windows build: fix lock_windows.c so it compiles. File was new
    in Xmlrpc-c 1.33 and never compiled. Fix girmem.cpp to use
    lock_platform, etc. instead of pthreadx, which was removed in
    Xmlrpc-c 1.33.

Release 1.35
============

Released 13.06.27.

Subversion directory release_number/01.35.00.

 * Abyss: fix wrong peer address with Unix socket channel made
   with ChannelUnixCreateFd(). Always broken (ability to get peer
   address was added in Release 1.07 (October 2006)).
 * JSON value formatting: Fix buffer overrun.
 * Build: build 'configure' with Autoconf 2.69 (previously built
   with 2.67).

Release 1.34
============

Released 13.03.30.

Subversion directory release_number/01.34.00

 * Build: fix libpthread dependency bug introduced in 1.33.00.
 * Test program build: include <unistd.h> instead of <sys/unistd.h>.

Release 1.33
============

Released 12.12.27.

Subversion directory release_number/01.33.00.

 * Make xmlrpc_value thread-safe (after construction, when the
   only modification allowed is to the reference count).
 * Client with Curl transport: fix bug which disables interruption
   unless you register a progress function for the transport.
   Introduced in 1.24 (September 2010).
 * Add xmlrpc_init(), xmlrpc_term().
 * Server: fix method add failure when signature string contains
   "I" (for 64 bit integer). Always broken (64 bit integer type
   was new in Xmlrpc-c 1.07 (October 2006)).
 * libxml2: fix memory leaks. Always broken (ability to use libxml2
   was added in Release 1.00 (October 2004)).
 * Abyss: Fix memory read through wild pointer upon interruption
   of server. Probably harmless.
 * Windows build: rename DLL configurations to avoid ambiguity
   between DLL and static library builds.

Release 1.32
============

Released 12.09.28.

Subversion directory release_number/01.32.00.

 * Abyss server: terminate sooner when the HTTP request handler
   requests shutdown. Formerly, after e.g. a 'system.shutdown'
   RPC, the server waited for the persistent TCP connections,
   including the one in which the RPC transaction was transported,
   to end (typically 15 seconds later). Now, it interrupts channel
   reads and writes on all connections so they will notice they
   are supposed to wind up and do so.
 * Abyss server: add basic server operation tracing with
   ABYSS_TRACE_SERVER environment variable.
 * Abyss server, XML-RPC Abyss server: add control of number of
   simultaneous connections and OS connection backlog.
 * Use random salt in hash values in built-in XML parser. Without
   this, a malicious user can create a putative XML-RPC call or
   response that takes a long time to parse, thus using excessive
   CPU resources. This code is adapted from true Expat's fix for
   CVE-2012-0876 to XML-RPC's fork of Expat, by Tyler Hicks
   <tyhicks@canonical.com>.
 * Server: Fix crash when string value in parameter list contains
   invalid UTF-8. Broken in 1.18 (March 2006). Diagnosed by Stephen
   Hansen, Programmer <stephen@tlo.com>.
 * Fix crash in built-in XML parser which causes a memory leak
   when it can't get additional memory (re-allocation fails). This
   code is adapted from true Expat's fix for CVE-2012-1148 to
   XML-RPC's fork of Expat, by Tyler Hicks <tyhicks@canonical.com>.
 * Build: fix build tree != source tree bug: no transport_config.mk.
   Broken in 1.10 (March 2007).
 * Windows build: properly export client class in xmlrpc-c_client++.dll.
   By Maksym Veremeyenko <verem@m1stereo.tv>
 * Build: don't build tools by default. Broken in 1.30 (March 2012).
 * Build: fix up how LDFLAGS, CFLAGS, and CXXFLAGS (make variables)
   are used. Deprecate LADD and CADD, which were meant for the
   same thing.
 * Build: fix make clean so it cleans src/cpp.
 * Build: fix so build of test programs does not fail if you didn't
   build client facilities.
 * Build: fix 'check'. By Tyler Hicks <tyhicks@canonical.com>.

Release 1.31
============

Released 12.06.30.

Subversion directory release_number/01.31.00.

 * Abyss XML-RPC server: make xmlrpc_server_abyss() fail instead
   of exiting program when it can't bind and listen.
 * Abyss server: Add ServerInit2() - fails instead of exiting
   program if it can't bind and listen.
 * Curl client XML transport: when server sends garbage instead
   of valid HTTP response, put the garbage (which is often an
   error message) in the error message.
 * Add xmlrpc_read_datetime_8601(),
   xmlrpc_c::value_datetime::iso8601Value().
 * xmlrpc_c::value_datetime: add ability to construct from and
   cast to xmlrpc_datetime.
 * Fix crash due to bogus memory free when xmlrpc_parse_value()
   fails. Broken in 1.07 (October 2006).
 * Abyss server: Fix bug: rejects request with colons in the host
   name (e.g. IPv6 address form "[::1]") as invalid.
 * Curl client XML transport: Fix error message when servers
   responds with non-HTTP garbage. Used to say HTTP response code
   is zero.
 * Curl client XML transport: fix occasional crash with modern
   Curl introduced in 1.28.
 * Abyss server: Fix crash when client doesn't specify access
   control. Broken in 1.25 (December 2011).
 * Abyss server: Improved formatting of IPv6 addresses for Abyss
   "channel info.". Also no more build-time dependency on nonstandard
   s6_addr16, introduced in 1.29.
 * Windows: Remove #include <windows.h> from public header file
   to avoid conflicts with other inclusions in user's program that
   include other variations of <windows.h>. By Maksym Veremeyenko
   <verem@m1stereo.tv>
 * Install: fix install of man pages to wrong directory. Broken
   in 1.18 (March 2009).
 * Windows build: Fix winsock2 conflict.

Release 1.30
============

Released 12.03.31.

Subversion directory release_number/01.30.00.

 * Add ability for Abyss and XML-RPC Abyss server to listen on a
   particular interface (IP address).
 * Abyss XML-RPC server: Fix bug in access control expiration.
 * xmlrpc, xmlrpc_pstream client programs: fix bug in display of
   unprintable ASCII as \xHH: shows \xff where it should be
   something else.
 * Windows Abyss: fix 16 byte per thread memory leak. Thanks Angelo Masci.
 * Build: add missing include of <ostream> to base.hpp. Broken in 1.26.
 * Build: remove --enable-tools option added in 1.18. User can
   just do 'make -C tools ' or 'make all' to get that.

Release 1.29
============

Released 11.12.31.

Subversion directory release_number/01.29.00.

 * Abyss: Add ChanSwitchUnixCreateIpV6Port: ability to listen for
   client connections on an IP Version 6 TCP port.
 * Curl client XML transport: Add 'referer' option.
 * Improved invalid UTF-8 error message.
 * xmlrpc client program: fix bug: doesn't accept b/f to mean
   boolean false. Broken since 1.07.
 * Fix crash when sending structure with a member value too large.
   Introduced in 1.21.
 * Fix Windows build, undefined macro XMLRPC_S_IWUSR introduced in 1.28.

Release 1.28
============

Released 11.09.27.

Subversion directory release_number/1.28.00.

 * Curl client: add "gssapi_delegation" option. Needed in some
   cases with newer Curl libraries to get back old function.
 * Fix bug: infinite loop parsing XML when a string or character
   data is longer than 1K in UTF-8. Introduced in 1.12.
 * Curl client: fix libcurl version in user-agent header. Always
   broken (user-agent function added in Release 1.03).
 * Client curl transport: fix bug: multiple authentication methods
   doesn't work; only one of them takes effect. Always broken.
 * C++ Curl client: fix bug: ignores proxy Curl transport options.
   Always broken.
 * Windows: Add VS2008 64 bit static library building. Remove MSVC
   6 project files. From now on, VS2008 will be the standard. The
   single set of project files build static and DLL, 32 bit and
   64.
 * Accomodate newer libcurl, which does not have <curl/types.h>.
 * Fix per-connection memory leak in libwww client XML transport.
   Present since the beginning.
 * Build: fix some parallel make forced ordering.
 * Build with --disable-abyss-threads: include <sys/wait.h> instead
   of <wait.h> in Abyss thread_fork.c.
 * Build of test programs: Fix "struct sockaddr_in" not defined
   in server_pstream.cpp.
 * Build: fix undeclared struct timespec.
 * Build: Work with systems that don't define S_IREAD in <sys/stat.h>.
 * C++: Reorder arrayValueSlice() and arrayValueAvrray() definitions
   in <xmlrpc-c/base.hpp> to please Clang.

Release 1.27
============

Released 11.06.27.

Subversion directory release_number/1.27.00.

 * Many changes to accomodate Mingw. May not work completely yet.
   By Maksym Veremeyenko <verem@m1stereo.tv>.
 * Windows build: update non-DLL project files to accomodate recent
   changes to tree. By Maksym Veremeyenko <verem@m1stereo.tv>.

   so user programs build. By Maksym Veremeyenko <verem@m1stereo.tv>.
 * Build: Fix detection of libwww, broken in 1.24.
 * Build: Don't use trailing comma in enum; not accepted by some
   C++ compilers.
 * Build: Add a user-defined default constructor for class callInfo
   to avoid compilation failure with recent GNU compilers.
 * Mac OS X build: include -install_name on library link so
   dependents can find it automatically. Thanks Joshua Root
   (jmr@macports.org).

Release 1.26
============

Released 11.03.26.

Subversion directory release_number/1.26.00.

 * Add output operator (operator<<) for xmlrpc-c::value::type_t.
 * JSON serializer: eliminate trailing commas that Internet Explorer
   doesn't like. Thanks Bo Lorentzen <bl@lue.dk>.
 * JSON serializer: improve human readability of JSON. Thanks Bo
   Lorentzen <bl@lue.dk>.
 * Fix JSON integer parsing and formatting broken in 1.25.
 * Build: Fix prototype/definition mismatch in libwww.cpp with
   some compilers (e.g. Solaris).
 * Build: Fix linking of xml-rpc-api2cpp with some linkers (e.g. Solaris).
