This patch is based on the latest patchset from Thomas Siedel
(thomas.ff@spin-digital.com).
The libvvenc patch has been changed with following changes:
avcodec: add external encoder libvvenc for H266/VVC
- sort includes alphabetically
- remove unneeded cast
- do not separate variables declaration and definition
- change if ((ret = func()) != 0) to: ret = func(); if (ret != 0)
- remove check for correct pix_fmt
- remove call of ff_side_data_set_encoder_stats

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.

+VVenC H.266/VVC encoder wrapper.
+
+This encoder requires the presence of the libvvenc headers and library
+during configuration. You need to explicitly configure the build with
+@option{--enable-libvvenc}.
+
+The VVenC project website is at
+@url{https://github.com/fraunhoferhhi/vvenc}.
+
+@subsection Supported Pixel Formats
+
+VVenC supports only 10-bit color spaces as input. But the internal (encoded)
+bit depth can be set to 8-bit or 10-bit at runtime.
+
+@subsection Options
+
+@table @option
+@item b
+Sets target video bitrate.
+
+@item g
+Set the GOP size. Currently support for g=1 (Intra only) or default.
+
+@item preset
+Set the VVenC preset.
+
+@item levelidc
+Set level idc.
+
+@item tier
+Set vvc tier.
+
+@item qp
+Set constant quantization parameter.
+
+@item subopt @var{boolean}
+Set subjective (perceptually motivated) optimization. Default is 1 (on).
+
+@item bitdepth8 @var{boolean}
+Set 8bit coding mode instead of using 10bit. Default is 0 (off).
+
+@item period
+set (intra) refresh period in seconds.
+
+@item vvenc-params
+Set vvenc options using a list of @var{key}=@var{value} couples separated
+by ":". See @command{vvencapp --fullhelp} or @command{vvencFFapp --fullhelp} for a list of options.
+
+For example, the options might be provided as:
+
+@example
+intraperiod=64:decodingrefreshtype=idr:poc0idr=1:internalbitdepth=8
+@end example
+
+For example the encoding options might be provided with @option{-vvenc-params}:
+
+@example
+ffmpeg -i input -c:v libvvenc -b 1M -vvenc-params intraperiod=64:decodingrefreshtype=idr:poc0idr=1:internalbitdepth=8 output.mp4
+@end example
+
+@end table
