19ee5f6dc4 nvdecoder: Reduce DPB size
Decoder will copy decoded picture to downstream buffer or output CUDA
memory even in case of zero-copy mode. Additional margin should be unnecessary
unless baseclass passed wrong max DPB size.

... and always use #ifdef instead of #if

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.
