Oleg Dobkin 32ba563cfc avutil/hwcontext_cuda: allow using primary CUDA device context 
Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

Philip Langdale 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.

Philip Langdale 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
