SVT-AV1 seems to have switched their default from CQP to CRF in February,
so enforce the controlling option accordingly.

It is now set generically for all those encoders whose corresponding
AVCodecDescriptor has the AV_CODEC_PROP_INTRA_ONLY.

Currently, the AV_PKT_FLAG_KEY is automatically set for audio encoders;
yet this is wrong, as both MLP and TrueHD have non-keyframes. So set it
based upon AV_CODEC_PROP_INTRA_ONLY (from the corresponding
AVCodecDescriptor) instead. This also sets it for some video codecs,
which is intended.

TrueHD/MLP is one of the audio formats with keyframes. Currently,
the generic encoding code just sets the keyframe flag for all
returned packets, yet this is wrong for these encoders and will
be changed in a future commit. So set the flag here for those
packets that ought to have it.

Sets vtctx->has_b_frames to 0 if the VideoToolbox compression
session will not emit B-frames (and, in consequence, no valid
DTSs). Required for the handling of invalid DTSs in
'vtenc_cm_to_avpacket' (line 2018ff) to work correctly and not
abort encoding with "DTS is invalid." when no B-frames are
generated.

Just check for the existence of the bsf. This is equivalent to
the old criterion of the AVCodecContext being a decoder.

It is now checked by FATE that no encoder capable of flushing
uses frame threads, so this now redundant runtime check can
be removed.

If an AVCodec has a private class, its priv_data_size must be > 0
and at the end of a successful call to avcodec_open2()
the AVCodecContext's priv_data must exist and its first element
must be a pointer to said AVClass. This should not be conditional
on priv_data_size being > 0 (which is tested by FATE) or
on the private context having been successfully allocated
(which has to have happened at that point). So remove these
preconditions to make the test stricter.

When a color indexing transform with 16 or fewer colors is used,
WebP uses "pixel packing", i.e. storing several pixels in one byte,
which virtually reduces the width of the image (see WebPContext's
reduced_width field). This reduced_width should always be used when
reading and applying subsequent transforms.
Updated patch with added fate test.
