d9a37af070 avutil/hwcontext_cuda: combine transfer functions 
Gets rid of some mostly duplicated code and adds the ability to do
hardware to hardware transfers.

7f149b0452 lavu/hwcontext_cuda: refactor context initialisation 
There's enough going on here now that it should not be duplicated
between cuda_device_create and cuda_device_derive.

a88449ffb2 lavu: add Vulkan hwcontext code 
This commit adds the necessary code to initialize and use a Vulkan device
within the hwcontext libavutil framework.
Currently direct mapping to VAAPI and DRM frames is functional, and
transfers to CUDA and native frames are supported.

Lets hope the future Vulkan video decode extension fits well within this
framework.

52d8f35b14 avutil/hcontext_cuda: Remove unnecessary stream synchronisation 
Similarly to the previous changes, we don't need to synchronise
after a memcpy to device memory. On the other hand, we need to
keep synchronising after a copy to host memory, otherwise there's
no guarantee that subsequent host reads will return valid data.

19d3d0c057 avutil/hwcontext_cuda: Define and use common CHECK_CU() 
We have a pattern of wrapping CUDA calls to print errors and
normalise return values that is used in a couple of places. To
avoid duplication and increase consistency, let's put the wrapper
implementation in a shared place and use it everywhere.

Affects:

* avcodec/cuviddec
* avcodec/nvdec
* avcodec/nvenc
* avfilter/vf_scale_cuda
* avfilter/vf_scale_npp
* avfilter/vf_thumbnail_cuda
* avfilter/vf_transpose_npp
* avfilter/vf_yadif_cuda
