Recent versions of Gettext are able to translate several formats
that are used in GNOME applications. This patch migrates from
Intltool to Gettext by using meson's i18n features.
build: Make bluetooth, network and wacom mandatory on linux
The bluetooh, network and wacom panels should not be optional
on linux, except on s390 systems which lack USB support. It
should also not be built at all on other systems.
NetworkManager supports marking a connection as metered, meaning
that connection is e.g. charged by its usage or extremely limited.
When a network is metered, background network usage must cease
and the behavior of the various OS pieces must be adjusted.
This patch adds a switch to set a connection as metered or not.
The property is imediately propagated to NetworkManager.
