... and add support CUDA context sharing similar to glcontext sharing. Multiple CUDA context per GPU is not the best practice. The context sharing method is very similar to that of glcontext. The difference is that there can be multiple context object on a pipeline since the CUDA context is created per GPU id. For example, a pipeline has nvh264dec (uses GPU #0) and nvh264device0dec (uses GPU #1), then two CUDA context will propagated to all pipeline.
