Log Message:
Update zzuf to version 0.15

The necessary patches have been submitted upstream.
This still does not build with PKGSRC_FORTIFY yet though.

List of intermediate commits:
* Prepare 0.15 release.
* Do not use rand() within fseek(), it might break reproducibility.
* Work around an issue with fseek() diversion. Closes #7.
* More verbose debug messages.
* Merge pull request #12 from edmcman/feature/retain_file_extension_in_copy_mode
* Also include alloca.h
* Retain file extension in copy mode.
* Merge pull request #11 from \ 
CERTCC-Vulnerability-Analysis/feature/add_opmode_null_to_run_without_fuzzing
* Add new "null" opmode which doesn't mutate the file.
* Export VERBOSE=1 in Travis so that the test suite outputs debug information.
* Add #pragma once directives in all our headers, for safety.
* Tell Travis to try to build on OS X, too.
* Add Travis build status to README.
* Move Travis builds to the container-based infrastructure.
* Tell Travis to bootstrap before running configure.
* Add a .travis.yml configuration file for CI.
* Disable the mmap regression test on OS X.
* Hopefully fix OS X compilation now. Fixes #5.
* Disable unnecessary weak symbol declaration.
* Merge pull request #4 from x9prototype/master
* Merge pull request #1 from x9prototype/x9prototype-patch-1
* Update libzzuf/lib-stream.c
* zzuf: set program version to 0.14 and prepare release.
* win32: using <stdint.h> instead of defining our own types.
* misc: fix a few minor issues found by static code analysis.
* sys: unsatisfying workaround for an issue with libasan.
* win32: clean up some Windows code.
* libzzuf: protect library initialisation with a mutex.
* build: remove spurious binary file.
* libzzuf: fix compiler warnings by adding declarations for functions that are \ 
unlikely to be exposed by system headers.
* Allow debug_str to be provided a negative length count for convenience.
* zzuf: fix a minor inconsistency between short and long options when compiled \ 
on a system with a useless rlimit().
* doc: group command line options by category in the man page.
* stream: fix a nasty bug that completely messed up with the streambuf structure \ 
tracking. Now when the new streambuf position is exactly at the end of the \ 
previous streambuf, we only fuzz the streambuf if new data is available (i.e. \ 
when streambuf_count != 0); otherwise, it just means that we?re at the end of \ 
the file, waiting for new read orders.
* debug: minor tweak to the debug string formatter.
* debug: refactor a lot of buffer debug functions using a shared formatter.
* test: use the -d flag in unit tests so that we can find potential errors in \ 
the debug() function calls.
* misc: rename a lot of _zz_-prefixed variables.
* test: add a regression test for a bug in our mmap function.
* zzuf: add a -X flag for hexadecimal dumps.
* debug: try to output as much debug output as possible and make debug() thread \ 
safe on Unix platforms.
* stream: rename a few functions for clarity.
* stream: fuzz the whole stream buffer upon opening.
* stream: refactor some streambuf getter functions.
* test: add a new regression test for a bug at stream EOF.
* stream: rename ?s? to ?stream? for consistency.
* mem: fix a buffer overflow bug in the mmap() replacement.
* misc: factor several common tests into one must_fuzz_fd() function.
* test: add a regression test for a bug in our mmap function.
* misc: C99 refactoring; put variable declarations closer to their first use
* misc: typo of the ass.
* win32: some compilation fixes introduced by refactoring for Linux.
* doc: update copyright and URLs.
* zzuf: replace a critical section with a simple spinlock.
* misc: move a lot of generic stuff to a new util/ source subdirectory.
* win32: some mingw32/mingw64 warning and compilation fixes.
* build: remove ChangeLog, as it?s convenient enough to have it in Git.
* misc: various compilation warning fixes and copyright updates.
* libzzuf: fix fseeko64 parameter type.
* fork: document more code and fix a bug reported by Will Newton.
* test: several fixes in the testsuite.
* misc: now that Visual Studio supports it some 15 years later, switch to C99.
* misc: minor fixes for compilation warnings.
* win32: Windows-specific compilation fixes.
* win32: add spinlock implementation for Windows.
* win32: update to newer mingw compiler version.
* build: remove the libcaca dependency and embed code instead.
* build: refresh build system.
* build: fix a few compilation warnings.
* core: add a lightweight spinlock to protect the list of file descriptors.
* sys: fix coding style.
* fix crash on windows 32-bit and compute_patch_size
* win32: add some console handling function diversions.
* win32: add more explicit error messages and add support for 0xb8 opcode.
* add relocate_hook to improve api hooking, fix dll name string comparison (no \ 
case sensitive), fix used after free on win32, add more hooks related to async \ 
file access
* build: fix compilation by including <wchar.h> and checking for regwexec.
* cosmetic: get rid of CRLF line endings.
* add new hook for windows (CreateFileMapping(A|W), MapViewOfFile, ReadFileEx), \ 
re-enable option -U, start to port network on windows
* port zzuf to win64 (amd64)
* add regex feature for win32
* change the method of hooking, now we disassemble the beginning of the targeted \ 
function and insert a jump to the new function.
* start to implement hotpatch hook on win32 port, but some API don't look to use \ 
it for some reason (e.g. kernel32!ReadFile)
* win32 port starts to fuzz executable (only few functions related to file \ 
handling are implemented)
* fix tmp file creation on win32, start to implement handling of win32 exception \ 
with GetExitCodeProcess
* on win32, use a named pipe and IOCP to read stdout, stderr and debugfd correctly.
*
* win32: add debug information to the function diversion code.
* linux: fix a few compilation warnings.
* Fix a weird problem with lib6 versioned symbols.
* osx: do not enforce flat namespace in copy mode on OS X.
* Win64 support in the VS solution.
* Fix wrong pointer types in the network range structures.
* Fix line endings.

* Implement ReOpenFile and fix a few Win32 compilation warnings.
* Fix Win32 intermediate build directories.
* Fix missing ZZUF_DEBUGFD passing and debug function availability.
* Fix a bug in the %i formatting and implement %S.
* Get the debug channel to work on Win32.
* Treat %x arguments as unsigned in the printf reimplementation.
* Fix the printf reimplementation to properly handle INT_MIN.
* Disable select() on Win32. It is not supported on non-sockets.
* Remove useless PARENT_FD/CHILD_FD hack.
* Make it easier to dynamically allocate the debug filedescriptor later.
* Filedescriptor 0 is the debug channel, not stdin! Fix that.
* Proper child command line construction on Win32. There is no need to hardcode \ 
stuff for debugging purposes any longer.
* Inherit stdin/stdout/stderr in the child process under Win32.
* Remove useless code for Win32 diversions.
* Mark diverted Win32 functions as __stdcall, it's the correct calling convention.
* Divert ReadFile() and CloseHandle().
* Drop Visual Studio 2008 support and require the 2010 version. The 2010 express \ 
version is free to use and it's a lot better.
* Fix compilation warnings on Win32.
* Divert CreateFileW in addition to CreateFileA.
* Fix the Linux build to accomodate with the new Win32 features.
* CreateFile() diversion proof of concept.
* Add a mechanism for Win32 diversions.
* Fix a bug caused by undefined function call precedence.
* Fix zzat compilation on Win32 and create a .vcxproj file for it.
* Minor Win32 code simplification in sys.c.
* Divert AttachConsole() and AllocConsole() for debugging purposes.
* Full support for ASLR in the Win32 loader.
* Refactor the DLL initialisation code to allow several diversions.
* Improve the DLL injection code. Now seems to work rather well under Windows. \ 
But it needs a lot of polishing.
* Do not build ASLR binaries on Windows for now.
* Fix Win32 build.
* Add a few comments in the code for new Win32 strategies.
* Make check-zzuf-r-ratio slightly more tolerant.
* New operating mode "copy". It uses temporary files instead of \ 
preloading libzzuf into the process.
* Grammar.
* Add a regression test for our Gentoo __fread_chk() bug.
* Fix old typos in check-utils.
* Add fortify versions of libc calls to zzat.
* Fortify functions actually have extra arguments. Fix that.
* Update TODO list.
* Revert any potential overriding macro before declaring a new function.
* Add support for fortified glibc functions (__fgets_chk, __read_chk, etc.).
* Rename zzcat to zzat to avoid conflicts with zziplib.
* Clean up ChangeLog generation.
* Split check-build into check-source and check-win32.
* Add an OS X build script that generates fat binaries.
* Add missing svn:ignore properties.
* On OS X, resident_size is actually in bytes, not pages. Fixing memory check \ 
routine.
