386268dfff Add some simple fallbacks for normal bit allocation failure. 
This allows encoding with lower bitrates by decreasing exponent bits first,
then decreasing bandwidth if the user did not specify a specific cutoff
frequency.

795063db3b Copy bap from previous block when exponent strategy is EXP_REUSE. 
We can do this because exponents are the only bit allocation parameters which
change from block-to-block currently.

Approx. 25% faster overall encoding.

27af78cf0e Redesign encode_exponents_blk_ch() so that duplicate exponent sets are no 
longer required. This gets rid of the temp buffer as well as encoded_exp in
AC3EncodeContext. It also allows for skipping the exponent grouping for
EXP_D15. 56% faster in encode_exponents_blk_ch().

cfff297d98 adpcm: Skip samples whose ssd calculation has wrapped around 
Wraparound in ssd is mainly avoided by subtracting the ssd of the
best node from all the others once it has grown large enough.

If using very large trellis sizes (e.g. -trellis 15), the frontier
is so large that the difference between the best and the worst is
large enough to cause wraparound, even if the ssd of the best one
is subtracted regularly.

When using -trellis 10 on a 30 second sample, this causes only a slight
slowdown, from 61 to 64 seconds.
