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.

Speed up AAC-HE SBR by 2% on S5L8701. Use MEM_ALIGN on critical arrays and avoid stalls in asm code.

Further changes to aac-he decoding. Refactor and rearrange dct tabs to be able to use consecutive addresses (this allows additional optimization for ARM through ldm-usage). Define a macro for identical butterfly operations and exchange 2 butterflyies with less compex operations.

Submit FS#11461. Major speedup for aac he profile (PP5002 +20%, PP5020 +15%, PP5022 +19%, MCF5249 +35%, MCF5250 +80%), still not realtime on most targets though. This change does a lot of refactoring in the sbr filters and the dct, switching to our optimized codeclib fft and tweaking IRAM usage.
