1e544f741a nvcodec: Move common methods to nvdecoder
... and remove all #ifdef from nvh264sldec implementation.
New helper methods will take care of OpenGL specific ones.

1f452c0577 nvh264sldec: Declare OpenGL related objects unconditionally
GstGLDisplay and GstGLContext are subclass of GstObject so we can
remove #ifdef for such object. This is prework for nvh265sldec.

e75049eb84 nvh264sldec: Fix wrong scaling list matrix scan order
Quatization matrix of NVDEC should be raster scan order but
h264parser stores it in zig-zag scan order. We need to convert
the matrix.

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.
