av_image_copy() accepts const uint8_t* const * as source;
lots of user have uint8_t* const * and therefore either
cast (the majority) or copy the array of pointers.
This commit changes this by adding a static inline wrapper
for av_image_copy() that casts between the two types
so that we do not need to add casts everywhere else.

This avoids unnecessary rebuilds of most source files if only the
list of enabled components has changed, but not the other properties
of the build, set in config.h.

Without this metadata section the ffmpeg utility thinks that the AMF encoder
does not support input from D3D11 and DXVA2 hardware surfaces, causing
hardware pipelines to fail.
Fixes#8953.
This commit follows the same logic as 061a0c14bb, but for the encode API: The
new public encoding API will no longer be a wrapper around the old deprecated
one, and the internal API used by the encoders now consists of a single
receive_packet() callback that pulls frames as required.

This ensures they will be reference counted, as required by the AVCodec.receive_packet()
API.
Should fix ticket #8386.

Added linux support for amf encoder through vulkan.
To use h.264(AMD VCE) encoder on linux amdgru-pro version 19.20+ and
amf-amdgpu-pro package(amdgru-pro contains, but does not install
automatically) are required.
This driver can be installed using amdgpu-pro-install script in
official amd driver archive.
Initialization of amf encoder occurs in this order:
1) trying to initialize through dx11(only windows)
2) trying to initialize through dx9(only windows)
3) trying to initialize through vulkan
Only Vulkan initialization available on linux.
Adds support for AMF initialisation from a DXVA2 (Direct3D9) device, and
then allows passing DXVA2 surfaces into an AMF encoder.

Supplying a hardware input frame which is not in the input hardware frames
context is not allowed by the API, so additional code to handle it is not
necessary. Further, handling it automatically results in very low
performance - it is more appropriate to fail immediately so that the user
can fix their incorrect setup.
If the user supplies a device or frames context then it is an error
not to use it; this is consistent with other hardware components.
Also factorise out the D3D11 initialisation and improve error
messages.
* commit '34c113335b53d83ed343de49741f0823aa1f8cc6':
Add support for H.264 and HEVC hardware encoding for AMD GPUs based on AMF SDK
Most of this was already present from 9ea6607d29,
this just applies some minor fixups and adds the general documentation.
