libavcodec/mpegaudiodec_template.c:885:97: warning: variable 'x' is uninitialized when used here [-Wuninitialized]

The buffer map/unmap code was in an early version of this before it
was committed, but the unmap was never removed.  While wrong, this
was harmless (and therefore unnoticed) because the buffers can't be
mapped at this point - all drivers just did nothing with the call.

When decoding interlaced pictures, the structure is reused to render
to the same surface twice.  The parameter buffers were not being
cleared, which caused the i965 driver to error out.

Use new H264Ref.reference field to track field picture flags. The
H264Picture.reference flag in DPB is now irrelevant here.

This is a regression from git commit a12d3188, and that affected
multiple interlaced video streams.

Those values are decoder-independent and are also use by the VA-API
encoder.

Its single forward declaration can be moved to the only place
it is used, like is done for all other dsp init files.

libavcodec/x86/videodsp.asm:128: warning: signed dword value exceeds bounds

Only works if packed headers are supported, where we can know the
output before generating the first frame.

The include was changed correctly in 4abe3b049d
but then mistakenly changed back by c359d624d3
(it's not just the NAL unit types which are used).

This fixes many warnings of the sort
warning: label alone on a line without a colon might be in error

This is intended as a replacement for the 'split' function exported by
some parsers.

This code is independent from the decoder, so it makes more sense for it
to to have its own header.

This will be useful in the following commits.

This way they can be reused by other code without including the whole
decoder-specific hevcdec.h
Also, add the HEVC_ prefix to them, since similarly named values exist
for H.264 as well and are sometimes used in the same code.

This is more consistent with the rest of libav and frees up the hevc.h
name for decoder-independent shared declarations.

This reverts commit d9dccc0389. There were
outstanding objections to this commit.

The decoding buffer index expected by D3D11VA is the one from the
ID3D11Texture2D not the one from the ID3D11VideoDecoderOutputView array
in AVD3D11VAContext.

Otherwise, when providing decoder slices that do not start from 0,
pictures appear in bogus order. For an invalid index crashes and
image corruption can occur.
