This commit is the analog of 3f11eac75741888c7b2b6f93c458766f2613bab5
for decoding: It sets the AV_FRAME_FLAG_KEY and (for video decoders)
also pict_type to AV_PICTURE_TYPE_I. It furthermore stops setting
audio frames as always being key frames -- it is wrong for e.g.
TrueHD/MLP. The latter also
It reuses the previous frame and does not code unchanged blocks.

If there are missing references, h264 decode does error concealment
by copying previous refs which means there will be duplicated surfaces.
Check long_ref and frame_idx in addition to surface when looking for
the other field to avoid trying to merge with wrong picture.
Also allow to merge with

ff_init_me() was being called after ff_update_duplicate_context(),
which caused the propagation of the initialization to other thread
contexts to be delayed by one frame.
In the case of mpeg4 (or flipflop_rounding), this would make the
hpel_put functions differ between the first thread (which

When there are multiple tiles in one slice buffer, use multiple slice
params to avoid sending the same slice buffer multiple times and thus
increasing the bitstream size the driver will need to upload to hw.
