Widgets (unlike Windows and Dialogs) returned by Gtk::Builder::get_widget*
start owned by the GtkBuilder object, the idea being that they will get
added to a container before the scope of the GtkBuilder object ends, and it
thus automatically gets destroyed.
But in the various ::create methods in pavucontrol, a pointer to the widget
gets returned, so that it can be added to a cointainer by the caller.
However as soon as the ::create method exits the GtkBuilder object owning
the widget, and thus also the widget gets destroyed, and we end up returning
free-ed memory.
This commit fixes this by making all ::create methods take a reference on
the widget before returning it, and having all the callers unreference the
widget after adding it to a container.

This allows us to set volumes up to ~153% aka +11dB.
Also show the current dB value in the UI - as pavucontrol is a bit more
developer-friendly than other volume UIs displaying this by default makes
sense.
Currently this module only really allows for devices to be renamed, so we add a new
dialog that can be activated by right clicking on devices (i.e. sinks/sources).
This dialog allows you to enter a new name which will be set via the extension
provided by the device-manager module.
Future work will allow you to manage (i.e. rename, delete etc) offline devices too.
This commit adds a combo box for selecting ports.
Overall this implementation could have taken two paths:
* Implement port selection as combo box.
* Implement port selection as a button.
I went for the first option as is done in selecting card profiles over the
second method used for selecting devices for streams. This seems more like
how a config option should be presented as opposed to a runtime type thing.
I reworked the way this was done so we can easily re-enable this as I think it's clearer when it's inactive
(the difference between toggled and not toggled is pretty minor).
With this abstraction we could reset the tooltip etc. too.
