Seungha Yang 42560c24df nvdecoder: Add support for D3D11 output
Since DXVA does not support some profiles such as HEVC RExt,
vendor specific decoding API is still required.
When decoder is negotiated with d3d11 caps, decoder will convert
semi-planar frame to planar since semi-planar format (e.g.,
DXGI_FORMAT_NV12) is not supported by CUDA/D3D11 interop.

Seungha Yang 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.

Seungha Yang 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.

Seungha Yang 80bbc71ec0 nvdecoder: Fix for HEVC 4:4:4 format decoding
Map chroma_format_idc == 3 (which means 4:4:4 subsampling) correctly,
also pass coded bitdepth for decoder initialization instead of
inferring it from output format since they can be different.
