0bd2483a75 replace MULL by MULH + shift in dct32() (code is very slightly faster, and the compiler should be able to optimize the shift away on 64bit archs)

e71bcc3798 flacenc - rice param search patch by (Justin Ruggles jruggle earthlink net 
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).

Note, if you think thats too harsh, look at the cvs history he has broken the regression tests many times and has not once
updated the checksums ...
regression test checksum change due to: movenc.c 1.46->1.47
