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.

d2aae6bb96 codecs: h264decoder: ref pic lists as decode_slice parameters 
Pass reference picture lists to decode_slice() vmethods

Change gstv4l2codech264dec and gstnvh264dec accordingly.

82f1d5e8be codecs: Change output_picture() to mandatory implementation 
GstVideoCodecFrame is expected to be consumed by subclass
per output_picture(). So the implementation cannot be optional.

c6b8157dd6 codecs: Pass the max_dpb_size to new_segment virtual 
On new_segment, the decoder is expected to negotiate. The decoder may want to
pre-allocate the needed buffers. Pass the max_dpb_size as this is needed to
determin how many buffers should be allocated.

00d04784d3 Move CODEC base classes into it's own library 
This introduce a library which contains a set of base classes which
handles the parsing and the state tracking for the purpose of decoding
different CODECs. Currently H264, H265 and VP9 are supported. These
bases classes are used to decode with low level decoding API like DXVA,
NVDEC, VDPAU, VAAPI and V4L2 State Less decoders. The new library is
named gstreamer-codecs-1.0 / libgstcodecs.
