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.

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.

ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.
