FS#12141 by Sean Bartell

Some of these were found with http://www.samba.org/junkcode/#findstatic. Changes of note:
* The old MDCT has been removed.
* Makefile.test files that create test programs for libatrac, libcook, and libffmpegFLAC have been removed, as they don't work. My project will have a replacement that works with all codecs.
* I've tried not to remove anything useful. CLIP_TO_15 was removed from libtremor because there's another copy (also commented) in codeclib.

Improved bitrev12, using a larger LUT to save one lookup, speeds up vorbis about 2% on beast, about 0.5% on h300

Rearrange the MDCT library lookup tables so that codecs can access them. Access them in cook. Remove old cook trig tables. Replace old 32x16 bit fixed point multiply code with faster ASM ARM/Coldfire versions using full 32 bit precision. Improves performance signficantly on PP5024 (~200% realtime for a 64k file) while saving a lot of memory and improving accuracy.
