d3c5fc815e v4l2codecs: Allow output caps to be updated
This change allow output caps to be updated even though we stay in
streaming state. This is needed so that any upstream updated to fields
like framerate, hdr data, etc. can result in a downstream caps event
being pushed.

Previously, any of these changes was being ignored and the downstream
caps would not reflect it.

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

cf3d64129b v4l2codecs: vp9: Fix reset_frame_context parameter
It was assumed that the kernel parameters would match with the bitstream value
but instead the author when with another set of value. Surprisingly, this
makes no difference with the resulting fluster score.

7a9e11ae1b v4l2codecs: vp9: Fix duplicating a duplicated picture
Duplicating a picture what was already a dup was leading to a crash. Rename
the custom picture flags as HOLDS_BUFFER to make its meaning clear. Then save
then ref and store the picture as userdata, so it can be obtained when
duplicating. Finally, mark the doplicated as HOLDS_BUFFER to avoid thinking it
holds a request.

13944cf3ee v4l2codecs: vp9: Make compressed hdr control optional
This is to supported by Mediatek VP9 driver. Mediatek handles
the forward probabilities in hardware hence does not need and
does not implement support for
V4L2_CID_STATELESS_VP9_COMPRESSED_HDR.

d7363bd838 v4l2codecs: Fix debug assertion in register functions
As now, we warn if the decoder have no support src pixel format, but that
warning is called before the type (hence the debug category) is initialized.
Fix this by moving the debug category init out of the type initialization,
into the register funcitons.

This will fix an assertion that occures in the register function and allow
relevant log to be seen by the users.

107088a658 v4l2codecs: Unify the src template caps format
Notably NV12_4L4 ended up being applied to only VP9 decoder. This fixes the
situation by using a central define for all static src pad templated formats.

a6eb1e7782 v4l2codecs: Fix renegotiation
If we hold the last reference to the allocator, leaving the device
streaming will cause an EBUSY error when trying to free the allocate
buffers.

d04fba93f8 v4l2codecs: vp9: Remove uneeded picture data
The GstV4l2Request now holds a reference on the picture buffer and is
recounted already. This effectively removes usage of GRefCount which is only
available in GLib 2.58, while we support 2.56.

Fixes #910

120b96a974 v4l2codecs: gstv4l2codecsvp9dec: implement a render delay
The v4l2 backend support delayed output for performance reasons.
It is then possible to use render delays to queue multiple requests
simultaneously, thus increasing performance.
