Without this, the compiler in theory could attempt to keep
things in float registers across the emms which would cause
bad things to happen.

This fixes out of global array reads.
The alternative solutions of checking the index or modifying the VLC tables
to prevent the index going outside are each about 1-2 cpu cyclces slower
per coded 4x4 block.
The alternative of padding the global tables directly is more ugly and
moving them to the context should benefit cache locality.

This prevents gcc from assuming that contents of it may have changed
between calls to vp56_range_get_prob(), thus preventing countless (and
unnecessary) movs. Decoding of sintel trailer goes from (avg+SG) 9.796
+/- 0.003 to 9.635 +/- 0.010.
We support every defined value for channel layout, bitrate and sample depth.
All other values are not unsupported, but reserved.
Update comments to say "are used" instead of "are known or exist".

We could also check the index but this would slow speed critical code

Make av_get_codec_tag_string() show codec tag string characters in a more
intelligible ways. For example the ascii char "@" is used as a number, so
should be displayed like "[64]" rather than as a printable character.
Apart alphanumeric chars, only the characters ' ' and '.' are used
literally in codec tags, all the other characters represent numbers.

There have been multiple user complaints about loosing this feature
while its not clear the 3% speedloss claims where real or fabricated.
My own testing indicates no statistically significant speed difference
both with mpeg2 and mpeg4, and if at all the code with lowres support
is a tiny bit faster than without.
This reverts commit 92ef4be4ab, reversing
changes made to 2e07f42957.

It should not have any user vissible effect.
We are discarding the new data in the decoder as no case is known

the header in the sample provided for ticket #1306 is not parsed correctly and thus
ffmpeg tries to decode the sample instead of abording the decoding.
I tested it with two other exr samples I have - one float, one half float - and
they still decode correctly.

In hybrid frames long window part ends at 36 samples for most of the cases
but at 72 for 8kHz case. For some reason decoder assumed it's 48 or even 36
samples, which caused wrong bitstream decoding for such blocks.
l3_25207.mpg from conformance suite demonstrates it the best.
