Rework of libfaad in several areas. Allow removal of malloc with a new define FAAD_STATIC_ALLOC (in common.h). For now malloc is not fully removed but used by a few arrays needed for AAC-HE SBR+PS only. Reason to keep malloc is to have this amount of memory available for AAC-LC files which might require large m4a tables. The changes make the allocation routines much smaller, better centralized and allow to move duplicated code from aac.c/raa.c to libfaad. The rework includes removal of (now and former) unused code as well.
