This makes sure that pointers from av_strdup are reallocable,
which is used in av_dict_set if the AV_DICT_APPEND flag is set.
Nothing should rely on pointers from av_strdup being aligned.

- Add special cases for offsets of 2, 3, or 4 bytes. This means the
offset is always >4 in the generic case, allowing 32-bit copies to
be used there.
- Don't use memcpy() for sizes less than 16 bytes.

The check uses check_func_header, since this function is
conditionally available depending on the targeted MSVCRT
version.

Overwriting the av_malloc etc. functions is not easily
possible anymore, even for systems that support overriding
symbols in shared libraries in principle.

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.

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.
