After bumping minimum glib requirements we get a bunch of

Upstream recommends avoiding the warnings by defining `EDS_DISABLE_DEPRECATED`,
see https://gitlab.gnome.org/GNOME/evolution-data-server/-/issues/332.
The pie kwarg was introduced with 0.49.0.
Amber ships 0.49.0, Amber-phone 0.51.0 and we have 0.56.2 in Debian,
so bumping the requirement should be unproblematic.
The CallsBestMatchView and CallsPhoneNumberQuery classes are written
in Vala because they may be generally useful and to leave open the
possibility of adding them to libfolks itself, which is written in
Vala.
This is an initial, static implementation of plugins. The
CallsApplication has a plugin name which can be changed with a new
--provider command line option. This plugin name is used to
instantiate the appropriate plugin when the application is activated.
From then on, the plugin cannot change.
In future, we can expand this support to include loading multiple
plugins at once, configurable through some UI. This will have
far-reaching implications though, and complicate things like
enumerating the provider hierarchy. There is also no practical
benefit right now; the mm and ofono plugins can't be used at the same
time because ModemManager and oFono don't play nice together, and the
whole raison d'être of the dummy plugin is undermined if you can make
use of one of the others. So for now, we just implement one static
plugin.
This will be needed by the next commit to display an "About" dialog via
the corresponding entry in the app menu that will be added.
This also adds the PACKAGE_URL, PACKAGE_VERSION and VCS_TAG
configuration data.
This avoids
WARNING: Project targetting '>= 0.40.1' but tried to use feature introduced in '0.42.0': gnome.mkenums_simple
0.42 is fairly old already and 0.40 isn't in a stable Debian release
either.
