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>.

While it is less featureful (and slower) than the built-in H264
decoder, one could potentially want to use it to take advantage
of the cisco patent license offer.

This option is only used by mpegvideoenc and openh264.
It is a very codec-specific option, so deprecate the global variant.
The openh264 option is dropped altogether since it is just a fallback
for -max_nal_size anyway.

openh264: Directly include the deprecation guards header
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
Most option values are simply unused or ignored and in practice the
majory of codecs only need to check whether to enable rle or not.
Add appropriate codec private options which better expose the allowed
features.

libopenh264enc: Add an option for controlling the frame skipping
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
This allows enabling the frame skipping, which is required for the
encoder to properly hit the target bitrate.

File libopenh264enc.c has been modified so that the encoder uses av_log()
to log messages (error, warning, info, etc.) instead of logging them
directly to stderr. At the time the encoder is created, the current
libav log level is mapped to an equivalent libopenh264 log level. This
log level, and a message logging function that invokes av_log() to
actually log messages, are then set on the encoder.
This contains further changes and simplifications by Michael Niedermayer
and Martin Storsjö.
