0b9f975b36 codecs: h264decoder: Add support for interlaced stream 
Initial support for interlaced stream. Subclass should implement
new_field_picture() vfunc. Otherwise, baseclass will assume that
subclass doesn't support interlaced stream.

Restrictions:
* Reference picture modification process for interlaced stream
  is not implemented yet
* PAFF (Picture Adaptive Frame Field) is not properly implemented.
* Field display ordering (e.g., top-field-first) decision should
  be enhanced via picture timing SEI parsing
* Gap in field picture should be handled

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.

dd425fe0fd adaptivedemux: Store QoS values on the element 
Storing it per-stream requires taking the manifest lock which can apparenly be
hold for aeons. And since the QoS event comes from the video rendering thread
we *really* do not want to do that.

Storing it as-is in the element is fine, the important part is knowing the
earliest time downstream.

113867766e codecs: vp9decoder: Add segmentation to picture. 
VA-API needs AC and DC quant scales for both luma and chroma, and the loop
filter level for current frame, but these values are not available outside
the private GstVp9Parser structure. And these values may change from frame
to frame, so they are picture specific.

This patch add GstVp9Segmentation structure array to GstVp9Picture to expose
it to derived classes. This approach is safer than passing the parser at
picture handling flow.

Also, this patch, in order to solve Documentation CI, mark as private the
GstVp9Picture structure.

5e3c7f2092 codecs: vp9decoder: Pass parser as new_sequence() parameter. 
In order to know the chroma format, besides profile, subsampling_x and
subsampling_y are needed (Spec 7.2.2 Color config semantics). These values are
in GstVp9Parser but not in  GstVp9Framehdr.

Also, bit_depth is available in parser but not frame header. Evenmore, those
values are copied to picture structure later.

In case of VA-API, to configure the pipeline, it is require to know the chroma
format and depth.

It is possible to know chroma and depth through caps coming from vp9parser, but
it requires string parsing. It would be less error prone to get these values
through the parser structure at new_sequence() virtual method.
