1c3e43a627 aacsbr: don't call sbr_dequant twice without intermediate read_sbr_data
Doing that doesn't make sense, because the only purpose of sbr_dequant
is to process the data from read_sbr_data.

bfd0e02dd6 avcodec/aacsbr: Split pre dequantization noise factors table
This allows removing a special case for the fixed point decoder and will
make error checks simpler

fd0bf457b7 avcodec/aacsbr_template: replace qsort with AV_QSORT
When sbr->reset is set in encode_frame, a bunch of qsort calls might get made.
Thus, there is the potential of calling qsort whenever the spectral
contents change.

AV_QSORT is substantially faster due to the inlining of the comparison callback.
Thus, the increase in performance should be worth the increase in binary size.

Tested with FATE.
