constraint_set1_flag should be set for constrained baseline and main
profiles, because the stream conforms to main profile.

constraint_set3_flag should be set for high profile when the stream
is intra-only.

constraint_set4_flag should always be set for main and high profiles
because interlaced encoding is not supported.

constraint_set5_flag should be set for main and high profiles when
B-frames are not used.

Also fix the setting of max_num_ref_frames - use the gop_size value
to check for intra-only rather than the constraint flag (which is not
necessarily set).

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).

This was added in libva 2.1.0 (VAAPI 1.1.0).  Use AVCodecContext.qmax,
matching the existing behaviour for qmin, and clean up the defaults so
that we only pass min/max when explicitly set.

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.

The codec sequence headers may contain fields which can overwrite the
fine parameters given in the specific settings (e.g. a crude bitrate
value vs. the max-rate / target-percentage / etc. values in
VAEncMiscParameterRateControl).  Always reapply all global parameters
after a sequence header to avoid this causing problems.

Include the common options, and also named options for setting the profile
and level.

The only common option here is low_power - it was previously supported
for H.264 only, that specific option is removed.

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.

Set the minimum version to 0.35.0 (libva 1.3.0) and remove redundant
configure tests.  This also allows the proprietary libmfx fork of libva,
which always shows the version number 0.99.0 (independent of the actual
version).

Nothing prevents it to work except this check. AV1 is already supported
