h264: decouple h264_ps from the h264 decoder
Main changes:
- a local GetBitContext is created for the various
ff_h264_decode_seq_parameter_set() attempts
- just like the old code, remove_sps() is adjusted so it doesn't remove
the pps.
Fixes decode with Ticket #631http://ffmpeg.org/pipermail/ffmpeg-user/attachments/20111108/dae58f17/attachment.mp4
but see next point as well.
- ff_h264_update_thread_context() is updated to work even when SPS
isn't set as it breaks current skip_frame code. This makes sure we
can still decode the sample from ticket #631 without the need for
-flags2 +chunks. (Thanks to Michael)
- keep {sps,pps}_ref pointers that stay alive even when the active
pps/sps get removed from the available lists (patch by michaelni with
additionnal frees in ff_h264_free_context() from mateo)
- added a check on sps in avpriv_h264_has_num_reorder_frames() to fix
crashes with mpegts_with_dvbsubs.ts from Ticket #4074http://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket4074/mpegts_with_dvbsubs.ts
- in h264_parser.c:h264_parse(), after the ff_h264_decode_extradata() is
called, the pps and sps from the local parser context are updated with
the pps and sps from the used h264context. This fixes fate-flv-demux.
- in h264_slice.c, "PPS changed between slices" error is not triggered
anymore in one condition as it makes fate-h264-xavc-4389 fails with
THREADS=N (Thanks to Michael)

Commit ca2f19b9cc 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.

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.

Move libavcodec managed objects from the public struct vaapi_context
to a new privately owned FFVAContext. This is done so that to clean up
and streamline the public structure, but also to prepare for new codec
support, thus requiring new internal data to be added in there.
The AVCodecContext.hwaccel_context, that holds the public vaapi_context,
shall no longer be accessed from within vaapi_*.c codec support files.

Deprecate older VA pixel formats (MOCO, IDCT) as it is now very unlikely
to ever be useful in the future. Only keep plain AV_PIX_FMT_VAAPI format
that is aliased to the older VLD variant.
This is an API change.

Use new H264Ref.reference field to track field picture flags. The
H264Picture.reference flag in DPB is now irrelevant here.
This is a regression from git commit d8151a7, and that affected
multiple interlaced video streams.
