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.

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.
