Fix color fading: previously color could fade to red when
volume level for red color was actually never reached.
Display volume value on right side.
Use red color only if clipping is needed.

Fixes probing of truehd/mlp files with a lot of frames in between the
major sync frames. The spec allows a distance of up to 128 frames in
between major sync frames, which leads to the probing code not reaching
the desired score.

ff_aac_tableinit is a macro in the case of hardcoded tables, so wrap
that up in a function (similar to how the decoder template does it) and
use that as the argument for ff_thread_once().

This speeds up aac_tablegen to a ludicruous degree (~97%), i.e to the point
where it can be argued that runtime initialization can always be done instead of
hard-coded tables. The only cost is essentially a trivial increase in
the stack size.

Even if one does not care about this, the patch also improves accuracy
as detailed below.

Performance:
Benchmark obtained by looping 10^4 times over ff_aac_tableinit.

Sample benchmark (x86-64, Haswell, GNU/Linux):
old:
1295292 decicycles in ff_aac_tableinit,     512 runs,      0 skips
1275981 decicycles in ff_aac_tableinit,    1024 runs,      0 skips
1272932 decicycles in ff_aac_tableinit,    2048 runs,      0 skips
1262164 decicycles in ff_aac_tableinit,    4096 runs,      0 skips
1256720 decicycles in ff_aac_tableinit,    8192 runs,      0 skips

new:
21112 decicycles in ff_aac_tableinit,     511 runs,      1 skips
21269 decicycles in ff_aac_tableinit,    1023 runs,      1 skips
21352 decicycles in ff_aac_tableinit,    2043 runs,      5 skips
21386 decicycles in ff_aac_tableinit,    4080 runs,     16 skips
21299 decicycles in ff_aac_tableinit,    8173 runs,     19 skips

Accuracy:
The previous code was resulting in needless loss of
accuracy due to the pow being called in succession. As an illustration
of this:
ff_aac_pow34sf_tab[3]
old : 0.000000000007598092294225
new : 0.000000000007598091426864
real: 0.000000000007598091778545

truncated to float
old : 0.000000000007598092294225
new : 0.000000000007598091426864
real: 0.000000000007598091426864

showing that the old value was not correctly rounded. This affects a
large number of elements of the array.

Patch tested with FATE.

Avoid decoding a frame to get the codec parameters while the codec
supports FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM. This is particulary useful
to avoid decoding twice images (once in avformat_find_stream_info and
once when the actual decode is made).

This hugely reduces the echo which was introduced with the previous
commit (though likely because previously everything was broken).
Makes LTP actually worthwhile now.

This commit attempts to mirror what the decoder does more closely
