This is similar to what the non-threaded code already does.

There is no point in delaying the check and it avoids bugs with a
half-initialized context.

Aligns frame dimensions to 16, which fixes potential invalid writes.

They end up overwriting past the line end.

Right now it will spuriously fail if the linesize is exactly equal to
the data width.

The decoder currently sets CODEC_FLAG_EMU_EDGE and relies on
get_buffer2() to always provide buffers with linesize == 2 * width.
This is wrong, since we place no such restriction on get_buffer2()
implementations.

Fix this by decoding into internal buffers and copying them to output
frames. Since this is a very obscure decoder, the performance hit should
not be an issue.

Some HEVC conformance streams zip on

were updated without changing the actual stream. Rename them in FATE
accordingly to make it easier to track future stream updates.

When downmixing 2.1 to 2-channel, if the 2.0 portion is Lt/Rt, sum-difference or dual mono, the actual output will be the same (with the LFE either mixed-in or discarded).

Also, when downmixing an arbitrary layout to 2-channel, if the bitstream contains custom downmix coefficients targeting Lt/Rt, then the output will be Lt/Rt rather than regular Stereo.

Includes a libavcodec utility function to update a frame's side data.

New versions of FreeType have moved the location of their API
header(s) and hide the location behind a macro.

Since the location changes between versions and no other way
to know the location exists, this workaround becomes necessary.

It has been disabled as 'broken' over 3 years ago in b716a792

This introduces some code duplication. However, much of it should go
away once the decoders stop using MpegEncContext.
