Release 2.2.2 Wed July 12 2017
        Security fixes:
             #43  Protect against compilation without any source of high
                    quality entropy enabled, e.g. with CMake build system;

             #60  Windows with _UNICODE:
                    Unintended use of LoadLibraryW with a non-wide string
                    resulted in failure to load advapi32.dll and degradation
                    in quality of used entropy when compiled with _UNICODE for
                    Windows; you can launch existing binaries with
                    EXPAT_ENTROPY_DEBUG=1 in the environment to inspect the
                    quality of entropy used during runtime; commits

Log message:
use the variant upstream chose (Debian also ran into the issue)

Log message:
build fix for OS X and Solaris from Tim Zingelman <tez@netbsd.org>:
OS X & Solaris have sys/random.h but not getrandom() so the build fails
with a missing symbol.                                                          \ 
Test linking the getrandom snippet instead of only compiling it
in configure.

Log message:
update of expat from 2.2.0 to 2.2.1 (mostly security fixes and cleanup)

Security issues fixed:
CVE-2017-9233, CVE-2016-9063, improve fix for CVE-2016-5300

fixed regression from fix to CVE-2016-0718

Cleanup: Drop AmigaOS 4.x, Borland C++ Builder, OpenVMS, Open Watcom,
Visual Studio 6.0 and Pre-X Mac OS support

Log message:
update to 2.2.0
changes:
-security patches which we already had in pkgsrc are integrated
-Use more entropy for hash initialization than the original fix
 to CVE-2012-0876
-Resolve troublesome internal call to srand that was introduced
 with Expat 2.1.0 when addressing CVE-2012-0876

Log message:
add patches from upstream to fix possible crashes and memory corruption
on malformed input (CVE-2016-0718)
Description: The Expat XML parser mishandles certain kinds of malformed
input documents, resulting in buffer overflows during processing and error
reporting. The overflows can manifest as a segmentation fault or as memory
corruption during a parse operation. The bugs allow for a denial of service
attack in many applications by an unauthenticated attacker, and could
conceivably result in remote code execution.

bump PKGREV

also add an improvement to the fix for CVE-2015-1283 which was part
of the 2.1.1 release -- don't rely on defined behaviour on overflows
of signed integer operations, from upstream git:
https://sourceforge.net/p/expat/code_git/ci/f0bec73b018caa07d3e75ec8dd967f3785d71bde/

pkgsrc change: add a hint how to run the pkg's selftest (not enabled
permanently because this would add a dependency on C++)

Log message:
revert ABI/ABI bump for expat.

Not necessary and cuases problems.
