be1a839ca6 mem: add support for _aligned_malloc() as found on Windows
The check uses check_func_header, since this function is
conditionally available depending on the targeted MSVCRT
version.

1a65d50ee7 mem.c: fix wrong comment.
Overwriting the av_malloc etc. functions is not easily
possible anymore, even for systems that support overriding
symbols in shared libraries in principle.

14f063d294 mem: Consistently return NULL for av_malloc(0)
Plain POSIX malloc(0) is allowed to return either NULL or a
non-NULL pointer. The calling code should be ready to handle
a NULL return as a correct return (instead of a failure) if the size
to allocate was 0 - this makes sure the condition is handled
in a consistent way across platforms.

This also avoids calling posix_memalign(&ptr, 32, 0) on OS X,
which returns an invalid pointer (a non-NULL pointer that causes
crashes when passed to av_free).

Abort in debug mode, to help track down issues related to
incorrect handling of this case.

518cdff81f Fix posix_memalign() usage when libavutil is compiled outside FFmpeg.
To use posix_memalign() "#define _XOPEN_SOURCE 600" have to be defined.
FFmpeg configure defines it from the command line through config.mak,
but when libavutil is used outside of FFmpeg the define is missing.
