7589647c13 av1parse: Do not return error when expectedFrameId mismatch
According to the SPEC:
  The frame id numbers (represented in display_frame_id, current_frame_id,
  and RefFrameId[ i ]) are not needed by the decoding process, but allow
  decoders to spot when frames have been missed and take an appropriate action.

So we should just print out warning and should not return error in parser when
mismatching. The decoder itself is already robust to handle the reference missing.

Fixes #3622

cd14b0892e codecparsers: av1: Clip max tile rows and cols values
Clip tile rows and cols to 64 as describe in AV1 specification
to avoid writing outside array range but preserve sb_cols
and sb_rows value which are used to futher computation.

6785c7d378 av1parser: Fix segmentation params update
Even if the segmentation feature value is not updated,
the parsed "segmentation_update_map" and "segmentation_temporal_update"
values should not be cleared as it's referenced during lower
level bitstream parsing. Also, don't use assert() in parser
unless it's clearly impossible condition.

465d146864 codecparser: AV1: fix reference frame ordering
In AV1 specifications earliest_order_hint is initialized at
beginning of the process and not before each frame ordering.

FFMPEG parser does the same.

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
