05458f05e0 v4l2codecs: vp9: Drop frames on non-keyframe format change
V4L2 does not yet support this feature, this will skip over the
transition portion up to the next keyframe.

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

It is then possible to use render delays to queue multiple requests
simultaneously, thus increasing performance.
