Xpra: Ticket #1825: multi window nvfbc

Split from ticket:1801#comment:5.

It should be possible to use a single nvfbc capture instance for multiple monitors and just adjust the buffer offsets.

Detected a memory leak during testing for #1823. Only occurs with nvfbc CUDA buffers and nvenc. Downloading to system memory before re-uploading to a CUDA buffer with XPRA_NVENC_GPU_MEMCOPY=0 (introduced in r19151) does not help. Using a non-nvfbc source for video does not leak either.

r19153 fixes this but I'm not 100% sure why that is. The image wrapper method was being called before this change, just maybe not from the right thread or not with the correct CUDA context.

The shadow pointer shown on the client may be at the wrong location in 2.3, this is fixed in 2.4: r19603.
