lavc: deprecate the use of AVCodecContext.time_base for decoding
...
When decoding, this field holds the inverse of the framerate that can be
written in the headers for some codecs. Using a field called 'time_base'
for this is very misleading, as there are no timestamps associated with
it. Furthermore, this field is used for a very different purpose during
encoding.
Add a new field, called 'framerate', to replace the use of time_base for
decoding.

mpegvideo: operate with pointers to AVFrames instead of whole structs
...
The most interesting parts are initialization in ff_MPV_common_init() and
uninitialization in ff_MPV_common_end().
ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL
checks for Picture.f, because these functions can be called on
uninitialized or partially initialized Pictures.
NULL pointer checks are added to ff_thread_release_buffer() stub function.

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.

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XvMC has long ago been superseded by newer acceleration APIs, such as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.
