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.

fba807bead nvh264sldec: Add support for output-delay to improve throughput performance 
NVDEC API support delaying getting decoded output, and recommended
delay by API document is 4 frames. In case that throughput is
more critical factor than latency, we can prefer delayed output
as recommended by NVIDIA.

7a53d7a4aa codecs: h264decoder: Store reference picture type using enum value 
Managing reference picture type by using two variables
(ref and long_term) seems to be redundant and that can be
represented by using a single enum value.

This is to sync this implementation with gstreamer-vaapi so that
make comparison between this and gstreamer-vaapi easier and also
in order to minimize the change required for subclass to be able
to support interlaced.

This refcount based way would be helpful for sharing nvdec frame among
multiple codec pictures and later zero-copy use case.

e921a07715 codecs: h264decoder: Pass GstVideoCodecFrame to output_picture() 
All subclasses are retrieving list to get target output frame, which
can be done by baseclass. And pass the ownership of the GstH264Picture
to subclass so that subclass can clear implementation dependent resources
before finishing the frame.

7a024a740f codecs: h264decoder: Don't attach extra ref of GstH264Picture to GstVideoCodecFrame 
The lifecycle of GstH264Picture is being managed by our DPB
implementation. If it's still required, subclass can do that
by itself in the new_picture() method.

4d585c64d1 nvcodec: Add suppport for environment based primary h264 decoder implementation 
Introduce GST_USE_NV_STATELESS_CODEC environment to allow user to select
primary nvidia decoder implementation. In case the environment
GST_USE_NV_STATELESS_CODEC=h264 was set, old nvidia h264 decoder element
will not be registered. Instead, both nvh264dec and nvh264sldec
factory name will create gstcodecs based new nvidia h264 decoder element.

9c21923f04 nvcodec: Add H264 stateless codec implementation 
Introduce GstH264Decoder based Nvidia H.264 decoder element.
Similar the element factory name of to v4l2 stateless codec,
this element can be configured with factory name "gstnvh264sldec".
Note that "sl" in the name stands for "stateless"

For now, existing nvh264dec covers more profile and formats
(e.g., interlaced stream) than this implementation.
However, this implementation allows us to control lower level
parameters such as decoded picture buffer management and therefore
we can get a chance to improve performance in terms of latency.
