4299596d16 codecs: h265decoder: Fix a typo of NumPocTotalCurr when process ref pic list. 
We should use the NumPocTotalCurr value stored in decoder, which is a calculated
valid value, rather than use the invalid value in the slice header. Most of the
time, the NumPocTotalCurr is 0 and make the tmp_refs a very short length, and
causes the decoder's wrong result.
By the way, the NumPocTotalCurr is not the correct name specified in H265 spec,
its name should be NumPicTotalCurr. We change it to the correct name.

791f1da7b8 nvcodec: nvsldec: Refactor graphics api resource handling 
* Move GL context object to GstNVDecoder object, and remove
  duplicated handling of each codec decoder element
* Don't create GL context too early. We can create it only if
  we need to negotiate with downstream gl element.

71564f471d nvcodec: nvdecoder: Move to refcount based GstNvDecoderFrame 
This refcount based way would be helpful for sharing nvdec frame among
multiple codec pictures and later zero-copy use case.

f330b5ae62 h265decoder: Sync with the H264 implementation 
This ensures that we get the last reference to picture being outputed,
avoiding GstBuffer structure copies and simplifying the buffer management.
