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.
Based on a patch by Philip Langdale <philipl@overt.org>.

According to the MediaSDK documentation the idr_interval value has
a different meaning depending on the codec:
0 in H264 means make every I-frame IDR, in HEVC it means to have
it only at the beginning.
1 in H264 means every other I-frame is not-IDR, in HEVC it means
that every I-frame is IDR.
Keep the behaviour consistent between the two encoders by increasing
by 1 internally the idr_interval value for HEVC.

Only on Windows the software plugin is available.

This way they can be reused by other code without including the whole
decoder-specific hevcdec.h
Also, add the HEVC_ prefix to them, since similarly named values exist
for H.264 as well and are sometimes used in the same code.

This is more consistent with the rest of libav and frees up the hevc.h
name for decoder-independent shared declarations.

This code will be shared with h264.

The b_frame_strategy option is only used by mpegvideoenc, qsv, x264, and
xavs, while b_sensitivity is only used by mpegvideoenc.
These are very codec-specific options, so deprecate the global variants.
Set proper limits to the maximum allowed values.

Use 8 B-frames and modify the GOP size to be a multiple of the B-frame
count.

Should fix some leaks on init failure.

Declare a named enum, not a variable with anonymous enum type.
