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).

0b52626eb0 Do not read full byte when less than 8 bits are still to be read. 
Does not make a difference with any of my samples, but current
code does not make much sense.

4f8ff17e75 The AAC frame header uses 13 bits for the frame size, so the buffer should 
have room for such a frame.  A frame that large seems unlikely in a valid
file, but leaving room for it spares us the need to check it elsewhere.
Moving the buffer to the end of the struct made debugging this easier.
