The 'operator' property was added to gstframepositioner so that
blending modes in the compositor could be accessed. This was done
by accessing the pad of the compositor class, and referencing the
'operator' property in that pad. Getters and Setters were also
created so that the 'operator' could be accessed by software that
is based on GES, such as Pitivi.

GstGLVideoItem is required to render input video in the overlay's qml.
And currently qmlgloverlay requires to set this GstGLVideoItem to its widget property.
Instead of fetching GstGLVideoItem from the overlay's root object (root-item prop),
and setting it back as a widget (widget prop),
proposing to use found GstGLVideoItem in the current object hierarchy (passed in qml-scene) by default.
Also useful in Python, which solves the issue when casting gpointer <=> QQuickItem* is required.

Some capture devices might not provide channel mask value which will
result in capturing failure because of unknown channel mask in case
that device generates more than 2 channels. Although it might not
be correct, we can assume channel mask with the given number of channels.

uridecodebin assumes that refcount of decodebins stored in pending_decodebins
are floating but it might not be true in case that refcount of the decodebin
was touched in other places. To avoid the floating refcount issue,
hold strong reference.

Lookup will now maintain the full list of possible IP address(es).
We can now iterate over all available addresses in case certain
address families (IPv6) are disabled or try connecting to additional
addresses for the clients.

Would spew warnings on the rpi4 when calling into
gst_v4l2_object_get_codec_caps() from the probe_and_register()
function since the v4l2_debug category initialisation would
only be done later as part of the element/device provider
registration.
Also log things in the probe function to the v4l2 category
instead of the default category while we're at it.

Protect clearing probes against concurrent modification which might happen
due to dispose does NOT guarantee that the object is not used anymore, as
it could be referenced again and so being continued used.
So, as in the rest of places where probes hook list is used, on dispose
it should be accessed holding the mutex "GST_OBJECT_LOCK (pad);" as
GHookList is not thread-safe.

When posting buffering messages there are no safe places or timing to avoid
deadlocks.
Previously the code was trying to be "smart" by only forwarding serialized
queries if the queue was empty ... but that could happen when queue2 hadn't yet
posted a 100% buffering message. Meaning the pipeline might be paused and
pushing a serialized query downstream might never complete.
Therefore let's completely disable forwarding of serialized queries when
`queue2` is used as a buffering element (meaning `ALLOCATION` and `DRAIN`
queries).

`@` references are used to reference function parameters, struct members
or enum variants _within_ the current type/function. It cannot and
should not be used to reference to types outside that.
Since C has no notion of member functions it makes little sense to
prefix these with `@`; most of the documentation here was referencing
functions on _different_ types anyway.
