Do not pointlessly call ff_alloc_packet multiple times,
and fix an infinite loop by clamping the maximum
number of bits to target in the algorithm that does
not use lambda.

Also remove one pointless zero initialization in rangecoder.c.

This should be moved to tablegen at some point.

Choose band type (codebook) zero, count its bits, and mark the other
states as unnavigable.

On cygwin, math.h needs to be included before float.h because of a bug
in the system headers. Including libavutil/libm.h first works around
this issue.

Reduce scalefactors in non-zero bands that underflow by twice as much as those
in bands that just fail to hit psy targets.

The minimal codebook to encode the band without clipping is used (as is done in the TLS).

This still provides plenty of dynamic range, makes every move legal, and greatly reduces the search space.
