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.

The old implementation, upon receiving a frame on the main
input, would request an overlay frame if necessary. This could
generate an infinite recursion, off-by-one frame mismatch and
other harmful effects, especially it the split filter is present
upgraph.

The new implementation uses the linear approach: it uses two
buffer queues for frames received out of turn and forwards
request_frame calls to the input where a frame is necessary.

This only happens if some filter somewhere is bogus,
but it helps debugging.

Maybe someone can add a check in the second gif encoder (rgb24), because I'm not sure where it should be added.

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".

This fixes the issue that since the last merge -async caused 2 aresample
filters to be inserted
users that generate funny timestamps in a filtergraph should probably
manually insert a aresample filter where they need it.
