This adds common code to query driver support and set appropriate
address/size information for each slice. It only supports rectangular
slices for now, since that is the most common use-case.
Add a larger warning more clearly explaining the consequences of missing
packed header support in the driver. Also only write the extradata if the
user actually requests it via the GLOBAL_HEADER flag.
Choose what types of reference frames will be used based on what types
are available, and make the intra-only mode explicit (GOP size one,
which must be used for MJPEG).
Query which modes are supported and select between VBR and CBR based
on that - this removes all of the codec-specific rate control mode
selection code.
Previously there was one fixed choice for each codec (e.g. H.265 -> Main
profile), and using anything else then required an explicit option from
the user. This changes to selecting the profile based on the input format
and the set of profiles actually supported by the driver (e.g. P010 input
will choose Main 10 profile for H.265 if the driver supports it).
The entrypoint and render target format are also chosen dynamically in the
same way, removing those explicit selections from the per-codec code.
Change the slice/parameter buffers to be allocated dynamically.

Use AVCodecContext.compression_level rather than a private option,
replacing the H.264-specific quality option (which stays only for
compatibility).
This now works with the H.265 encoder in the i965 driver, as well as
the existing cases with the H.264 encoder.

Only do this when building for a recent VAAPI version - initial
driver implementations were confused about the interpretation of the
framerate field, but hopefully this will be consistent everywhere
once 0.40.0 is released.
(cherry picked from commit ff35aa8ca4069bf1543adeec4c28e51e4a012eee)
This change makes the configured GOP size be respected exactly -
previously the value could be exceeded slightly due to flaws in the
frame type selection logic.
(cherry picked from commit 37fab0661a760b2a9d727939d72e629acee1a6ef)
Only works if packed headers are supported, where we can know the
output before generating the first frame.
(cherry picked from commit 0cf86fabfa5820596cca2cfead63c6f8df76c3f2)
This improves behaviour with drivers which do not support packed
headers, such as AMD VCE on mesa/gallium.
(cherry picked from commit 892bbbcdc171ff0d08d69636a240ffb95f54243c)
This allows better checking of capabilities and will make it easier
to add more functionality later.
It also commonises some duplicated code around rate control setup
and adds more comments explaining the internals.

vaapi_encode: Maintain a pool of bitstream output buffers
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
Previously we would allocate a new one for every frame. This instead
maintains an AVBufferPool of them to use as-needed.
Also makes the maximum size of an output buffer adapt to the frame
size - the fixed upper bound was a bit too easy to hit when encoding
large pictures at high quality.
These are all trivial to merge.
* commit '92fdea37477b5a2d1329e5ef0773e24473fa8f12':
vaapi_h265: Add -qp option, use it to replace use of -global_quality
vaapi_h265: Add constant-bitrate encode support
vaapi_h264: Add encode quality option (for quality-speed tradeoff)
vaapi_h264: Add -qp option, use it to replace use of -global_quality
vaapi_encode: Add support for codec-local options
vaapi_h264: Add constant-bitrate encode support
vaapi_encode: Refactor slightly to allow easier setting of global options
