libtremor: port over ffmpeg's windowing code

2011-09-22T11:47:51+00:00

Use the windowing approach from ffmpeg in tremor, does the mdct doubling, windowing and overlap add in one go.
Also uses less memory so all the processing buffers fit in iram on targets with small iram for the common blocksizes (256/2048) now.

Speeds up decoding of vorbis files by 3MHz for 256/2048 and 20MHz for 512/4096 files on h300.
Speeds up decoding of vorbis files by 3MHz for 256/2048 and 4.5MHz for 512/4096 on the beast.
Speeds up decoding of vorbis files by 0.3MHz for 256/2048 and 1MHz for 512/4096 on c200v1.

libtremor: pass the floor1 lookup table pointer as a param to the render_line function to make this a little nicer.

Move ffmpeg functions to their own file to avoid mixing code under different liceses in the same file. Licensing is fun!
