c5bd0faee3 nvdecoder: Add support for HEVC GBR output
... and use P012 format for 12bits instead of P016

bd25c2738e nvdecoder: Copy output frame if needed
Even if decoder is negotiated with CUDA memory feature, if downstream
proposed no buffer pool, assume that the pool size is unknown.
And disable zero-copy if there's no more free output surface.
Or, in case of reverse playback, always copy frames.

1aa9e74aaf cudadownload: Always download CUDA memory if it's bound to decoder
Decoder bounded CUDA memory is allocated by driver and the pool size
is fixed. Since we don't know how many buffers would be held by
downstream non-CUDA element, we should download such CUDA memory
and release it back to decoder.

f831b92540 nvdecoder: Add support for reconfiguration
Instead of creating new decoder instance per new sequence,
re-use configured decoder instance via cuvidReconfigureDecoder()
API. It will make output surface reusable without re-allocation.
Also, in order for application to be able to reserve higher resolution
output surface, "init-max-width" and "init-max-height" properties are
added to each decoder.

03425bc702 nvdecoder: Add support for CUDA zero-copy in stateless decoder
Wrap mapped decoder output surface using GstCudaMemory and
output without any copy operation. Also, for application to be able to
control the number of zero-copyable output surfaces,
"num-output-surfaces" property is added.
