Use AVCodecContext.compression_level rather than a private option,
replacing the H.264-specific quality option (which stays only for
compatibility).
This now works with the H.265 encoder in the i965 driver, as well as
the existing cases with the H.264 encoder.

cutoff is implemented as an option global to lavc, but supported only
by a few encoders. This fact is now reflected in its documentation. ac3's
support of this option is added for completeness.

Pass the cutoff option from lavc's avcodec_options[] to libmp3lame's
lowpass option, without allowing to adjust its default behavior.

There is really no need for two aac wrappers, we already have
libfdk-aac which is better. Not to mention that faac doesn't
even support HEv1, or HEv2. It's also under a license which is
unusable for distribution, so it would only be useful to people
who will compile their own ffmpeg, only use it themselves (which
at that point should just use fdk-aac).

The default value of -1 indicates that ffmpeg should determine the channel
mapping automatically, which was the behavior before this commit.
Unless the -mapping_family argument is provided, behavior is unchanged.

Since the next commit removes the experimental flag from the encoder
it's better to update the documentation which has been around in its
current form for as long as the encoder itself.

The -threads option is ignored with libkvazaar since it does not have
any of the AV_CODEC_CAP_{FRAME,SLICE,AUTO}_THREADS capabilities. This
commit removes the incorrect documentation as well as the no-op of
setting the number of threads in libkvazaar encoder.

This option is extremely codec specific and only a few codecs employ it.
Move it to codec private options instead: mpegenc family supports only 3
values, xavs and x264 use 5, and xvid has a different metric entirely.
