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.

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

v4l2codecs: h264: Properly set pic_num/frame_num
...
The V4L2 uAPI uses pic_num for both PicNum and ShortTermPicNum. It also
doe the same for both FrameNum and LongTermFrameIdx. This change does
not change the fluster score, but fixed a visual corruption noticed
with some third party streams.

Set minimum sizeimage such that there is enough space for any overhead
introduced by the codec.
Notably fix a vp9 issue in which a small image would not have a
bitstream buffer large enough to accomodate it.

v4l2codecs: Fix segfault when destroying non-detached allocator
...
The GstV4l2CodecAllocator dispose function clears `self->decoder` but
the finalize function then tries to use it if the allocator has no been
detached yet.
Fix by detaching in the dispose function before we clear
`self->decoder`.

codecs: h264decoder: Use GstFlowReturn everywhere
...
boolean return value is not sufficient for representing the reason
of error in most cases. For instance, any errors around new_sequence()
would mean negotiation error, not just *ERROR*.
And some subclasses will allocate buffer/memory/surface on new_picture()
but it could be failed because of expected error, likely flushing
