(using .asf as our .ogg muxer depends on libogg, nut muxer depends on libnut and vorbis in avi/mpeg is not really a good idea)

this makes frames a few bytes smaller (0.1% for high bitrate but >1% for low bitrates)

slight PSNR/bitrate increase

some PSNR/bitrate improvement for adaptive quant

Originally committed as revision 7346 to svn://svn.ffmpeg.org/ffmpeg/trunk

some PSNR/bitrate gain if adaptive quant is used
initalize qscale_table correctly (it was pretty much random since the qp->lambda change)
  this probably has not much effect as the table isnt used currently IIRC

tabs removed and regression.sh fixed (it was missing in the patch) by me

1) search for optimal rice parameters and partition order. i also
modified the stereo method estimation to use this to calculate estimated
bit count instead of using just the pure sums.

2) search for the best fixed prediction order

3) constant subframe mode (good for encoding silence)

Note that the regression test for the decoded wav file also changed.
This is due to FFmpeg's FLAC decoder truncating the file, which it did
before anyway...just at a different cutoff point.  The generated FLAC
files are still 100% lossless.

With this update, FFmpeg's FLAC encoder has speed and compression
somewhere between "flac -1" and "flac -2".  On my machine, it's about
15% faster than "flac -2", and about 10% slower than "flac -1".  The
encoding parameters are identical to "flac -2" (fixed predictors, 1152
blocksize, partition order 0 to 3).
