132eddd7b9 av1decoder: Clear highest_spatial_layer per sequence header
Clear the value to default zero, indicating that no spatial scalability
layer is used.

c92128f6b0 av1decoder: Don't error out by dropped OBU
OBU can be dropped if the current layer is not in selected operation
point

f1a52c5ea0 av1decoder: Fix wrong spatial layer validation
Highest spatial id and temporal id is independent, and should not drop
temporal enhance layer by the previous condition. Note that
the decision for dropping OBU based on operation point is being
handled in gst_av1_parser_identify_one_obu() already.

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()

3d56f133f8 codecs: av1decoder: Add the highest_spatial_layer field.
As SPEC says, when multi spatial layer exists, we should only output
one frame with the highest spatial id from each TU. We now store the
highest spatial layer information in the base class in order to let
the sub class handle different layers easily.

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.

80107d4a86 cdoecs: av1: Copy system_frame_number in duplicate_picture
The system_frame_number is notably used by V4L2 decoder as a unique
indentifier for the frame that was decoded. This value is used to tell driver
which frame to reference, as V4L2 does not have an efficient mechanism to
otherwise pass back the frames.

For this reason, and because it is more ligical, copy the original
system_frame_number into the duplicate picture instead of using the current
frame.

049655c824 codecs: av1: Fix state when we show existing keyframe
Showing existing keyframe have special meaning in AV1. All the references
frame will be refreshed with the original keyframe information. The refresh
process (7.20) is implemented by saving data from the frame_header into the
state. To fix this special case, load all the relevant information into the
frame_header.

As there is nothing happening in between this and the loading of the key-frame
into the state, this patch also remove the separate API function, using it
internally instead.

Fixes #1090

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)
