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.

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.

Extend av_log2 in codeclib into a generic for scanning for set bits, which can provide either log2 or leading-zero-count output, and can force mapping 0 input to 0 output if needed (otherwise 0 input produces undefined result). Replace av_log2 in lib/codeclib.h, floor_log2 and wl_min_lzc in libfaad/common.c and common.h, and count_leading_zeros in libalac/alac.c with macros using bs_generic.

Changes to make libfaad compile in Rockbox. Also remove compiler warnings, use some IRAM (IRAM usage needs reviewing) and drastically reduce the stack usage
