The libaom doxy says that a value of 0 for the threads fields is
equivalent to a value of 1, whereas for avctx->thread_count it means
the maximum amount of threads possible for the host system.
Use av_cpu_count() to get the correct thread count when auto threads
is requested.

aom_codec_get_global_headers() is not implemented as of libaom 1.0.0 for AV1, so
we're forced to extract the relevant header OBUs from the first packet and propagate
them as packet side data.

Explicitly identify decoder/encoder wrappers with a common name. This
saves API users from guessing by the name suffix. For example, they
don't have to guess that "h264_qsv" is the h264 QSV implementation, and
instead they can just check the AVCodec .codec and .wrapper_name fields.
Explicitly mark AVCodec entries that are hardware decoders or most
likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing
API users listing hardware decoders in a more generic way. The proposed
AVCodecHWConfig does not provide this information fully, because it's
concerned with decoder configuration, not information about the fact
whether the hardware is used or not.
AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software
implementations in case the hardware is not capable.

Corpus VBR mode is a variant of standard VBR where the complexity
distribution midpoint is passed in rather than calculated for a specific
clip or chunk.
The valid range is [0, 10000]. 0 (default) uses standard VBR.

This option is only used by mpegvideoenc, x264, xavs, and vpx.
It is a very codec-specific option, so deprecate the global variant.

Add an allowed value to the private options for frame_skip_cmp which
seems to have been forgotten, but perfectly working.
The libvpx frame dropping feature uses one of such option
(frame_skip_threshold) without the other three. For this reason rename
the option to something more consistent with the other libvpx variables.
