ecd7455e96 aacenc: Fix issues with huge values of bit_rate.
Do not pointlessly call ff_alloc_packet2 multiple times,
and fix an infinite loop by clamping the maximum
number of bits to target in the algorithm that does
not use lambda.

  Large intensity stereo and PNS indices are legal. Clip them instead of erroring out. A magnitude of 100 corresponds to 2^25 so the will most likely result in clipped output anyway.

acc9f51fe1 aacenc: Trellis over scalefactors using an estimated codebook rather than every codebook.
The minimal codebook to encode the band without clipping is used (as is done in the TLS).

144c5e3dd2 aacenc: Only trellis over a column of 61 scalefactors (reduced from 256).
This still provides plenty of dynamic range, makes every move legal, and greatly reduces the search space.
