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.

23e99a7a77 codecs: set sys frame num before new_picture() 
Derive classes might need to operate on the current frame at their
new_picture() vmethod, so it would be needed to set system_frame_number
on picture before calling the vmethod.

5a29917a63 codecs: Add minimal state validation 
... to prevent requesting decoding before the preparation.
For instance, baseclass should not request decoding a picture if there
is no parsed valid headers, since subclass is most likely
not ready to decoding it.

ba3430a059 h265decoder: Fix for output and removal picture from DPB 
See C.5.2.2 Output and removal of pictures from the DPB.

If the number of pictures in the DPB is greater than or equal to
sps_max_dec_pic_buffering_minus1[HighestTid] + 1, then the picture
should be outputted.

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.

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.
