Stefano Sabatini 6b4c0be558 mem: define the MAX_MALLOC_SIZE constant and use it in place of INT_MAX
This makes re-dimensionating the constant simpler, since now it is
defined only in one place.

Ivan Kalvachev 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.
