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.

Some files contain a few additional, all-0 bits.
Check for that case and don't print incorrect "not supported"

For sbr_qmf_window_us there is even a question if it maybe
should be fully hardcoded all the time.
Since half of it is coded, it ends up in .data and not .bss.

This prevents various values from becoming stuck at NAN and

Now, nellymoserenc and aacenc no longer depends on dsputil. Independent
of this patch, wmaprodec also does not depend on dsputil, so I removed
it from there also.
Swapping buffer indices allows saving one memcpy that accounts for 1% of the

fails to decode, restore the last successful configuration.

Fixes Libav Bug 195.
This doesn't make the code handle sample rate or upsample/downsample
change properly but this is still a good sanity check.
