73eca738ac mpeg12dec: do not add stereo3D side data to a non-existing frame
User data is usually coded before slice data. That means the frame
the user data belongs to is not available while parsing the user data.
The stereo3D side data has to use the same indirection over the private
context as pan scan information and A53 captions.

6d93307f8d mpeg12: check scantable indices in all decode_block functions
Add checks to the fast functions used with CODEC_FLAGS2_FAST and move
the check for all other functions to before the invalid memory is
accessed. Fixes https://trac.videolan.org/vlc/ticket/9713 with
CODEC_FLAGS2_FAST.

19e30a58fc Deprecate obsolete XvMC hardware decoding support
XvMC has long ago been superseded by newer acceleration APIs, such as
VDPAU, and few downstreams still support it. Furthermore XvMC is not
implemented within the hwaccel framework, but requires its own specific
code in the MPEG-1/2 decoder, which is a maintenance burden.

93a51984a2 mpeg12: Ignore slice threading if hwaccel is active
Slice threading does not work with hardware acceleration, as decoding
is per-picture.  This fixes Bugzilla #542.

bf20cdbd86 mpeg12: skip frames consistently
The decoder did not start predicted frames with missing references but
called the end of frame handling on them anyway. This caused an
assertion in the VA API HW accelorator since it tried to render a
picture with uninitialized buffers.
