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.

Headroom in AAC SBR HF-generator's fixed point implementation of autocorrelation was too small. Fixes FS#12019.

Use MEM_ALIGN_ATTR in libfaad. Remove global array and re-use existing one.

More unification of FIXED_POINT and FLOAT. Small refactoring.

Also correct autocorrelation for yet undefined SBR_LOW_POWER. Unify FIXED_POINT and FLOAT implementation.

Correct autocorrelation function in libfaad. It used the wrong fract part for the multiplication macros. Introduce appropriate solution to avoid overflow.

Further libfaad cleanup. Make libfaad compilable for floating point. Floating point cannot be used as reference though, as errorous noise is the result.
