e6585c89ea cuda: Hide memory copy util function 
The method was intended to be used by only cudaupload/download elements
and not ready to be a part of public API

7ea3c55549 cudaupload,cudadownload: Use shared GstD3D11Device context if possible 
Handle d3d11 device context in set_context() method with
additional device compatibility check so that only NVIDIA GPU
associated d3d11 device can be configured in the element.
And clear old d3d11 device per set_info() for d3d11 device to be
updated as well.

812bb14f28 cudaupload,cudadownload: Don't simplify caps in transform_caps 
The simplified caps might not be a subset of filter caps
and basetransform will complain about it.

d9f08e17f1 cudadownload: Passthrough in case of CUDA -> SYSTEM 
GstCudaMemory supports CPU access via CUDA pinned host memory already
and it would show faster memory transfer performance between
GPU and CPU than copying from/to normal system memory.
If downstream supports video meta, we can passthrough CUDA memory.

are all disabled.

e5132a8508 cudaupload,cudadownload: Add support for dGPU NVMM 
Implement NVMM <-> CUDA, GL, SYSTEM memory conversion. Jetson is
not supported yet. Note that NVMM <-> GL interop on Jetson platform
is supported by GstGL

Some example pipelines are:
- Convert NVMM to GstGL memory
  nvv4l2decoder ! "video/x-raw(memory:NVMM)" ! cudadownload ! "video/x-raw(memory:GLMemory)" ! glimagesink

- Upload system memory to NVMM and encode
  video/x-raw,format=NV12 ! cudaupload ! "video/x-raw(memory:NVMM)" ! nvv4l2h264enc

- Convert NVMM to GstCUDA memory and encode
  nvvideoconvert ! "video/x-raw(memory:NVMM)" ! cudaupload ! "video/x-raw(memory:CUDAMemory)" ! nvh264enc
