34c5a6660a h264: codec reinit: remove statements without effect 
avctx->coded_{height,width} will always equal h->{height,width} since
init_dimensions() does that explicitly, Size changes are detected by
changes in mb_{height,width} earlier and propagated through the
needs_reinit variable.

b3d905b702 dcadec: Delete redundant init_get_bits call

thing it does is calling dca_parse_frame_header, which takes care of
the needed initialization.

f6774f905f 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.
