cb93df0dcb avcodec/aacsbr_tablegen: always initialize tables at runtime
This gets rid of virtually useless hardcoded tables hackery. The reason
it is useless is that a 320 element lut is anyway placed regardless of
--enable-hardcoded-tables, from which all necessary tables are trivially
derived at runtime at very low cost:

sample benchmark (x86-64, Haswell, GNU/Linux, single run is really
what is relevant here since looping drastically changes the bench). Fluctuations
are on the order of 10% for the single run test:
39400 decicycles in aacsbr_tableinit,       1 runs,      0 skips
25325 decicycles in aacsbr_tableinit,       2 runs,      0 skips
18475 decicycles in aacsbr_tableinit,       4 runs,      0 skips
15008 decicycles in aacsbr_tableinit,       8 runs,      0 skips
13016 decicycles in aacsbr_tableinit,      16 runs,      0 skips
12005 decicycles in aacsbr_tableinit,      32 runs,      0 skips
11546 decicycles in aacsbr_tableinit,      64 runs,      0 skips
11506 decicycles in aacsbr_tableinit,     128 runs,      0 skips
11500 decicycles in aacsbr_tableinit,     256 runs,      0 skips
11183 decicycles in aacsbr_tableinit,     509 runs,      3 skips

Tested with FATE with/without --enable-hardcoded-tables.

7ebe12fc55 mmaldec: Add mpeg2 decoding support
Register mmaldec as mpeg2 decoder. Supporting mpeg2 in mmaldec is just a
matter of setting the correct MMAL_ENCODING on the input port. To ease the
addition of further supported mmal codecs a macro is introduced to generate
the decoder and decoder class structs.

27d23ae074 aacenc: add support for encoding files using Long Term Prediction
Long Term Prediction allows for prediction of spectral coefficients
via the previously decoded time-dependent samples. This feature
works well with harmonic content 2 or more frames long, like speech,
human or non-human, piano music or any constant tones at very low
bitrates.

It should be noted that the current coder is highly efficient and
the rate control system is unable to encode files at extremely
low bitrates (less than 14kbps seems to be impossible) so this
extension isn't capable of optimum operation. Dramatic difference
is observable with some types of audio and speech but for the most
part the audiable differences are subtle. The spectrum looks better
however so the encoder is able to harvest the additional bits that
this feature provies, should the user choose to enable it. So
it's best to enable this feature only if encoding at the absolutely
lowest bitrate that the encoder is capable of.

b629c67ddf AAC encoder: memoize quantize_band_cost
The bulk of calls to quantize_band_cost are replaced
by a call to a version that memoizes, greatly improving
performance, since during coefficient search there is
a great deal of repeat work.

Memoization cannot always be applied, so do this in a
different function, and leave the original as-is.
