Add external encoder VVenC for H266/VVC encoding.
Register new encoder libvvenc.
Add libvvenc to wrap the vvenc interface.
libvvenc implements encoder option: preset,qp,qpa,period,
passlogfile,stats,vvenc-params,level,tier.
Enable encoder by adding --enable-libvvenc in configure step.

Implicitly disabled by 4679a474f0.
Given that no one has ever complained about this, this commit
removes the now dead code.

Drop reference to constants removed in 94eed68ace.
In particular, rename me_method to me_quality and add description for
supported values.
Address trac issue:
http://trac.ffmpeg.org/ticket/10003
In particular, clarify that it can either be set as a field of
AVCodecContext or as an x264 option, using a different specification.
Should address trac issue:

Add skip_frame support to qsvenc. Use per-frame metadata
"qsv_skip_frame" to control it. skip_frame option defines the behavior
of qsv_skip_frame.
no_skip: Frame skipping is disabled.
insert_dummy: Encoder inserts into bitstream frame where all macroblocks
are encoded as skipped.
insert_nothing: Similar to insert_dummy, but encoder inserts nothing.
The skipped frames are still used in brc. For example, gop still include
skipped frames, and the frames after skipped frames will be larger in
size.
brc_only: skip_frame metadata indicates the number of missed frames
before the current frame.

Add "slice" intra refresh type to h264_qsv and hevc_qsv. This type means
horizontal refresh by slices without overlapping. Also update the doc.

Currently AVBR is disabled and VBR is the default method if maxrate is
not specified on Linux, but AVBR is the default one if maxrate is not
specified on Windows. In order to make user experience better accross
Linux and Windows, use VBR by default on Windows if maxrate is not
specified. User need to set both avbr_accuracy and avbr_convergence to
non-zero explicitly and not to specify maxrate if AVBR is expected.
In addition, AVBR works for H264 and HEVC only in the SDK.

Add adaptive_i/b feature to hevc_qsv. Adaptive_i allows changing of
frame type from P and B to I. Adaptive_b allows changing of frame type
frome B to P.

Using parameter from AVCodecContext to reset qsv codec is more suitable
for MFXVideoENCODE_Reset()'s usage. Per-frame metadata is more suitable
for the usage of mfxEncodeCtrl being passed to
MFXVideoENCODE_EncodeFrameAsync(). Now change it to use the value
from AVCodecContext.
Because q->param is passed to both "in" and "out" parameters when call
MFXVideoENCODE_Query(), the value in q->param may be changed. New
variables are added to store old configuration, so that we can detect
real parameter change.

Enable dynamic QP configuration in runtime on qsv encoder. Through
AVFrame->metadata, we can set key "qsv_config_qp" to change QP
configuration when we encode video in CQP mode.

To do more accurate QP control, add min/max QP control on I/P/B frame
separately to qsv encoder. qmax and qmin still work but newly-added
options have higher priority.
