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.

h264: eliminate low_delay
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.

h264: decouple h264_ps from the h264 decoder
Make the SPS/PPS parsing independent of the H264Context, to allow
decoupling the parser from the decoder. The change is modelled after the
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.
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.

lavc: move the vaapi encoders further down in the list of codecs
Right now they are the first encoders for those codecs in the list, so
they are selected when the caller requests a codec by id.
Since they require special treatment, they should not be selected by
default if there are other encoders (e.g. libx264/5) available.

This can only be used if the input data happens to be laid out

This might not be supported on all encoders, so only enable it

omx: Add support for broadcom OMX on raspberry pi
The raspberry pi uses the alternative API/ABI for OMX; this makes
such builds incompatible with all the normal OpenMAX implementations.
Since this can't easily be detected at configure time (one can
build for raspberry pi's OMX just fine using the generic, pristine
Khronos OpenMAX IL headers, no need for their own extensions),
require a separate configure switch for it instead.
The broadcom host library can't be unloaded once loaded and started;
the deinit function that it provides is a no-op, and after started,
it has got background threads running, so dlclosing it makes it
crash.

The first byte contains compression level together with keyframe status.
When a frame is not interpreted correctly, its data is summed to the

vaapi_h264: Fix bit offset of slice data.
Commit ca2f19b9cc37be509d85f05c8f902860475905f8 modified the meaning of
H264SliceContext.gb: it is now initialised at the start of the NAL unit
header, rather than at the start of the slice header. The VAAPI slice
decoder uses the offset after parsing to determine the offset of the
slice data in the bitstream, so with the changed meaning we no longer
need to add the extra byte to account for the NAL unit header because
it is now included directly.
