c442c9bd5e codecs: Integrate H265 DPB full check into need_bump(). 
The current DPB check of H265 is not very correct. The current frame
is already in the DPB when we check whether the DPB is full.
For example, the DPB max size is 16 and we have 15 ref frames in the
DPB, so the gst_h265_dpb_delete_unused() cleans no one, and then plus
the current frame, the DPB is 16. This causes an error return, but in
fact, the stream is correct.
We now integrate the DPB full check into the need_bump() function.
We add the correct frame into to DPB and then check whether the picture
num is bigger than max_num_pics of DPB(which means there is no room for
the current picture). If true, we bump the DPB immediately.

f49f039ff2 codecs: h265decoder: Add support for interlaced stream 
* Invoke GstH265DecoderClass::new_sequence() method per interlaced
  stream status update so that subclass can update caps.
* Parse picture timing SEI and set buffer flags on GstH265Picture
  object. Subclass can refer to it like that of our h264decoder
  implementation.
* Remove pointless GstH265PictureField enum

db10288382 codecs: h265decoder: Make GstVideoCodecFrame hold the last reference of the buffer 
The functionality of passing the last reference of GstH265Picture
was silently dropped by the commit eeffd91109
This commit will make it work again.

eeffd91109 codecs: h265decocer: Rework for DPB management 
* Move all DPB bumping process into GstH265Dpb internal
* Handle DPB add process in GstH265Dpb struct
* Make implementation to be 1:1 mappable with hevc specification
* Fix wrong DPB bumping implementation especially when no_output_of_prior_pics_flag
  was specified.

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.

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.
