e065279529 h264: remove an artificial restriction on the number of slice threads 
This limit is now unnecessary, we can easily support an arbitrary number
of threads.

b77fffa127 h264: make slice threading work with deblocking_filter=1 
In such a case, decode the MBs in parallel without the loop filter, then
execute the filter serially.

The ref2frm array was previously moved to H264SliceContext. That was
incorrect, since it applies to all the slices and should properly be in
H264Context (it did not actually break decoding, since this distinction
only becomes relevant with slice threading and deblocking_filter=1,
which was not implemented before this commit). The ref2frm array is thus
moved back to H264Context.

370ddc7b38 h264: remove H264Context.pict_type 
It is not used for anything internally, just exported in the output
frames. So remove the indirection and set it directly in frame_start().

It is always unconditionally initialized in decode_postinit() and then
immediately used in one place further below. All the other places where
it is accessed are just useless fluff.

Make the SPS/PPS parsing independent of the H264Context, to allow

one done earlier for HEVC.

Move the dequant buffers to the PPS to avoid complex checks whether they
changed and an expensive copy for frame threads.

7fc329e2dd lavc: introduce a new decoding/encoding API with decoupled input/output 
Until now, the decoding API was restricted to outputting 0 or 1 frames
per input packet. It also enforces a somewhat rigid dataflow in general.

This new API seeks to relax these restrictions by decoupling input and
output. Instead of doing a single call on each decode step, which may
consume the packet and may produce output, the new API requires the user
to send input first, and then ask for output.

For now, there are no codecs supporting this API. The API can work with
codecs using the old API, and most code added here is to make them
interoperate. The reverse is not possible, although for audio it might.

From Libav commit 05f66706d1.

eae2ebded3 libxvid: Create extradata in init using a dummy frame 
Modifying global header extradata in encode_frame is an API violation
and only happens to work currently because mov writes its header
at the end of the file.

Heavily based off of a patch from 2012 by Nicolas George.
