8b8b0e2cd2 lavfi: add opencl tonemap filter
This filter does HDR(HDR10/HLG) to SDR conversion with tone-mapping.

An example command to use this filter with vaapi codecs:
FFMPEG -init_hw_device vaapi=va:/dev/dri/renderD128 -init_hw_device \
opencl=ocl@va -hwaccel vaapi -hwaccel_device va -hwaccel_output_format \
vaapi -i INPUT -filter_hw_device ocl -filter_complex \
'[0:v]hwmap,tonemap_opencl=t=bt2020:tonemap=linear:format=p010[x1]; \
[x1]hwmap=derive_device=vaapi:reverse=1' -c:v hevc_vaapi -profile 2 OUTPUT

7faa8d8b03 lavfi: Add OpenCL unsharp mask filter
Intended to replace existing opencl mode of the unsharp filter.
Supports many more pixel formats and works without immediate upload
and download of frame data.  The options are compatible with the
existing filter.

9204b2deea lavfi: Add OpenCL overlay filter
Input and output formats must be the same, the overlay format must be
the same as the input except possibly with an additional alpha component.
