Reimar Döffinger 0f96f0d996 aacenc: Fix issues with huge values of bit_rate. 
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.

Justin Ruggles 89eea6df28 aacenc: make sure to encode enough frames to cover all input samples. 
Currently, any samples in the final frame are not decoded because they are
only represented by one frame instead of two. So we encode two final frames to
cover both the analysis delay and the MDCT delay.

Nathan Caldwell dc7e7d4dd9 aacenc: Fix a bug where deinterleaved samples were stored in the wrong place.

This produced incorrect, but surprisingly listenable results.

Thanks to Justin Ruggles for the report.

Nathan Caldwell 24efdea7fd aacenc: Fix number of coefficients used in a LFE channel.

Nathan Caldwell 98add74e85 aacenc: Fix determination of Mid/Side Mode. 
In adjust_frame_information(), msc is incremented for each sfb in each
sub-window then compared against max_sfb which is for a single sub-window.

This resulted in frames using EIGHT_SHORT_SEQUENCE where the first few
sub-windows increment msc to a value that results in ms_mode == 2. Even
though only some of the bands are actually using Mid/Side.

Overall this improves quality, and vastly improves rate-control.
