The slice get's increased by 50 items if scrolled to the bottom
and reset to the initial 75 items if scrolled back to the top.
The defined threshholds make sure that the UX still feels smooth.
Having more than ~200 widgets in a GtkListBox comes with a very
performance impact. This is especially noticable during while the main
window is being realized (even if Calls already runs in daemon mode).
We can limit the amount of widgets by using a slice list model.
Fixes: #374
The volatile qualifier was mostly used for historical reasons,
the documentation for `g_once_init_enter()` and `g_once_init_leave()`
has the following to say:
While `location` has a `volatile` qualifier,
this is a historical artifact and the pointer passed to it
should not be volatile.

Slightly adapted for Calls.

Tag messages have been a bit inconsistent in the past, because we
created signed tags by hand.
With this change we can just `gbp tag` and get consistently named tags
and messages.
It's common to have spaces or other separator characters in telephone
numbers. If tel: link (example: tel:+1 855-698-1150) is clicked in browser all
unsupported characters are escaped (example: tel:+1%20(855)%20698-11-50).
15 ms does not seem to be enough time for phosh-antispam to be able
to hang up before the incoming call screen shows up. In my experiement,
90 looks to be the minimum time needed for the incoming call to not show up.
I put it to 100 ms just to be safe.
