9c84a72a25 Skip the bit allocation search if previous and current SNR offsets are the 
maximum value of 1023.
This speeds up overall encoding depending on the content and bitrate.
The most improvement is with high bitrates and/or low complexity content.

5128842ea2 10l: Fix mistake in r26044. Check increment bounds using actual increment 
instead of 64. This will change output in some cases, but it happens to not
affect the AC-3 regression tests.

ec44dd5fc2 Change the default dB-per-bit code from 2 to 3. 
This gives slightly better quality in PEAQ tests.
Code 3 gives a dBpb value of 2816 = -132dB (128 psd units = -6dB), which
corresponds to 22 bits. Since the exponents have an offset applied, the
16-bit source looks like 24-bit source to the bit allocation routine.
So using dBpb code=3 is a closer match to the exponent range.

Regression test refs updated for acodec-ac3, lavf-rm, and seek-ac3_rm.

e96dc767e4 Make sure that the 2nd CRC value does not match the AC-3 sync word. 
This is optional for encoders, but it's a good idea and has minimal impact
on performance.
This will change the output for some files, but it happens not to affect the
regression tests.

295ab2af6e Change FIX15() back to clipping to -32767..32767.

132041f06f While adding stereo rematrixing, I came across something that needs to 
be fixed even without adding the feature.  The output correctly uses 4
dummy values for the rematrixing flags in block-0, but the bit
allocation routine does not take these bits into account.  From what I
can tell, there was a patch in 2003 that corrected the output to make it
DVD and spec compatible, but it didn't correct the bit allocation.  It's
only 4 bits over the entire 6 blocks, so overflow errors would happen
rarely or never, but it's still worth fixing.  So here is a fix.
