Add erosion_opencl, dilation_opencl filters. Behave like existing erosion and dilation filters.

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

Behaves like existing convolution filter.

Behaves like the existing avgblur filter, except working on OpenCL
hardware frames. Takes exactly the same options.

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.

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.

This builds the float and fixed-point versions of dct32 separately
instead of #including the file in dct.c and mpegaudiodec.c.

These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.

Instead of defining functions in per-arch header files included
by the main cpu.c, define them normally and call them from the
generic one.

It contains optimizations that are not specific to i386 and
libavutil uses this naming scheme already.
