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.

The stats are a superset of the quality factor, also allowing the picture type and encoder "PSNR" stats to be exported
This also replaces the native by fixed little endian order for the affected side data
AV_PKT_DATA_QUALITY_FACTOR is left as a synonym of AV_PKT_DATA_QUALITY_STATS

This is necessary to preserve the quality information currently exported
with coded_frame. Add the new side data to every encoder that needs it,
and use it in avconv.

This returns something like "v12_dev0-1332-g333a27c". This is much more
useful than the individual library versions, of which there are too
many, and which are very hard to map back to releases or git commits.

This was suggested in the discussion about these functions
With this change the functions are available internally but are not
part of the public API

The header is not installed currently so the changes should not be in APIChanges

This reverts part of commit 19ed3e35a5.
New functions are added to fixed_dsp, so the documentation is changed
accordingly.

This function allows writing AVRationals as IEEE floats without the need
of platform dependant float operations

This is useful for client programs to ask for nv12 surfaces instead of the
current default (uyvy), since those are more efficient to decode to.
