90cea4fadf av1parse: Add temporal unit check when TD is absent.
The current manner for deciding the new temporal unit is based on
temporal delimiter(TD) OBU. We only start a new temporal unit when
the TD comes.
But some streams do not have TD at all, which makes the output "TU"
alignment fail to work. We now add check based on the relationship
between the different layers and it can successfully judge the TU edge.

a7ca0b2079 av1parse: let the parse continue when MISSING_OBU_REFERENCE error.
Some streams may have verbose OBUs before a valid sequence header. We
should let the parse continue rather than return a error.

348658dd0a av1parse: Continue when we fail to detect the alignment.
Some streams may have problematic OBUs at the beginning, which causes
the parse fail to detect the alignment and return error. For example,
there may be verbose OBUs before a valid sequence, which should be
discarded until we meet a valid sequence. We should let the parse
continue when we meet such cases, rather than just return error.

d334c08b55 av1parse: Set the "tu" as the default alignment.
The tu(temporal unit) is more widely used than the current alignment.
We now change the default alignment to tu.

2266f70d79 av1parse: Copy the PTS and DURATION when we create data.
We need to create header buffers for annex b format. This kind of
buffers should inherit the PTS and DURATION from the original buffers.

13f0128f7e codecparsers: av1parse: Add the DECODE_ONLY flag to output buffer.
When the alignment is ALIGN_FRAME and the output buf contains a frame
which is not to be shown, the GST_BUFFER_FLAG_DECODE_ONLY flag should
be set.

40213b5c75 av1parse: Use descriptive profile name instead of numeric
As per AV1 specification Annex A, AV1 profiles have explicit and
descriptive names for each seq_profile.
