2ede4011bf codecs: Keep track of non-decoding-essential input state change
In theory, input caps can be updated anytime at non-keyframe or
sequence boundary, such as HDR10 metadata, framerate, aspect-ratio
or so. Those information update might not trigger ::new_sequence()
or subclass may ignore the changes.

By this commit, input state change will be tracked by baseclass
and subclass will be able to know the non-decoding-essential
update by checking the codec specific picture struct
on ::output_picture()

6a4c42c03f codecs: Signal required DPB size for AV1,MPEG2,VP8, and VP9 via new_sequence()
Make all codecs consistent so that subclass can know additional DPB
size requirement depending on render-delay configuration regardless
of codec. Note that render-delay feature is not implemented for AV1
yet but it's planned.

Also, consider new_sequence() is mandatory requirement, not optional

9a364464f0 av1decoder: Sync duplicate_picture with VP9 one
Pass the current frame to the duplicate_picture callback. This makes it easier
to set the frame's output_buffer if we already have one available. Also
documented that unlike VP9, it is not optional to implement this as the
picture will populate the DPB if it is a key-frame. To ensure this, remove the
default implementation.

a7ceac50b2 vp9decoder: Copy system_frame_number in duplicate_picture
Just like AV1, copy the system_frame_number from the original picture to make
it clear they reference the same data.

43759ffeaa codecs: vp9: Also consider render_width/height
Also emits new_sequence if on keyframe and the render_width/height have
change. The subclass can always optimize this if the frame resolution
didn't change, the output caps needs to reflect this though.

a2b0837bc5 codecs: gstvp9decoder: copy frame->system_frame_number into picture
A comment in gstvp9picture.h states that picture->system_frame_number
should get its value from frame->system_frame_number, but in fact
it was never copied at all.

Fix it.

98dc7a64a0 codecs: gstvp9{decoder|statefulparser}: optionally parse compressed headers
Rework gstvp9{decoder|statefulparser} to optionally parse compressed headers.
The information in these headers might be needed for accelerators
downstream, so optionally parse them if downstream requests it.

88437a9c9b codecs: Use GST_VIDEO_DECODER_ERROR() only for decoding error case
The GST_VIDEO_DECODER_ERROR() should be used only for robust/error-resilient
decoding purpose. Any other error codes such as not-negotiated or flushing
should be returned without modified for upstream to be able to handle
it immediately. (for example, application might want to try other
decoder element on not-negotiated)

c6ec7f3ea4 codecs: vp9decoder: add support for render delay
Some decoding APIs support delayed output for performance reasons.
One example would be to request decoding for multiple frames and
then query for the oldest frame in the output queue.

This also increases throughput for transcoding and improves seek
performance when supported by the underlying backend.

Introduce support in the vp9 base class, so that backends that
support render delays can actually implement it.
