4cc7239d8b libavutil/hwcontext_opencl: fix a bug for mapping qsv frame to opencl 
mfxHDLPair was added to qsv, so modify qsv->opencl map function as well.
Now the following commandline works:

ffmpeg -v verbose -init_hw_device vaapi=va:/dev/dri/renderD128 \
-init_hw_device qsv=qs@va -init_hw_device opencl=ocl@va -filter_hw_device ocl \
-hwaccel qsv -hwaccel_output_format qsv -hwaccel_device qs -c:v h264_qsv \
-i input.264 -vf "hwmap=derive_device=opencl,format=opencl,avgblur_opencl, \
hwmap=derive_device=qsv:reverse=1:extra_hw_frames=32,format=qsv" \
-c:v h264_qsv output.264

2e08b39444 hwcontext: add av_hwdevice_ctx_create_derived_opts 
This allows for users who derive devices to set options for the
new device context they derive.
The main use case of this is to allow users to enable extensions
(such as surface drawing extensions) in Vulkan while deriving from
the device their frames are on. That way, users don't need to write
any initialization code themselves, since the Vulkan spec invalidates
mixing instances, physical devices and active devices.
Apart from Vulkan, other hwcontexts ignore the opts argument since they
don't support options at all (or in VAAPI and OpenCL's case, options are
currently only used for device selection, which device_derive overrides).

1c50d61a5a libavutil/hwcontext_opencl: Fix channel order in format support check 
The `opencl_get_plane_format` function was incorrectly determining the
value used to set the image channel order. This resulted in all RGB
pixel formats being set to the `CL_RGBA` pixel format, regardless of
whether or not they actually *were* RGBA.

This patch fixes the issue by using the `offset` and depth of components
rather than the loop index to determine the value of `order`.

61cb505d18 lavu/opencl: replace va_ext.h with standard name 
Khronos OpenCL header (https://github.com/KhronosGroup/OpenCL-Headers)
uses cl_va_api_media_sharing_intel.h. And Intel's official OpenCL driver
for Intel GPU (https://github.com/intel/compute-runtime) was compiled
against Khronos OpenCL header. So it's better to align with Khronos.

7faae6e745 hwcontext_opencl: DRM to OpenCL mapping for ARM 
Using cl_arm_import_memory.  Unfortunately, despite this not being a
standard extension, the function clImportMemoryARM() is not accessible
via clGetExtensionFunctionAddressForPlatform().  This means that it has
to be linked directly to the ARM OpenCL binary, so making a portable
binary is not possible as it is with all other mapping extensions.
