fe790f89e8 Use 15-bit LPC precision by default. This generally gives better compression 
results. Also update Ogg regression test.

overall flac encoding: 4-15% faster.
output is not identical to the previous algorithm due to occasional rounding
errors, but the differece is less than .0005% bitrate.
