Michael Niedermayer	21f70940ae	avutil/mem: remove av_realloc / av_malloc incompatibility warning memalign() is not guranteed to be compatible with free() or realloc() and for platforms in this category we have --enable-memalign-hack (which should be enabled automatically if such system is detected) Trying to somehow half support systems that can free() memalign memory but not reallocate it seems not worth the amount of work needed to keep 2 then incompatible allocation systems and ensure their seperation. That is unless this would affect a major platform on which we want to avoid the memalign hack code The warnings also cause wasted time and effort as people try to maintain a separation that does not exist currently.

Martin Storsjö	f637046d31	libavutil: Always use some GCC style attributes on clang Clang normally disguises as GCC (defining __GNUC__), and thus get all the normal GCC specific attributes. Clang can also work as a drop-in replacement for MSVC, and in these cases, it doesn't define __GNUC__, but defines _MSC_VER instead. Even in these setups, it still supports the GCC style attributes, thus use them, especially where there isn't any MSVC specific version, or where the MSVC specific version doesn't work on clang (for DECLARE_ASM_CONST).
