Boy this was hard.
To ease the pain of porting wireless-security to GTK4, add
a new WsFileChooserButton class that mimics the behavior of
a button that triggers a filechooser, as per the migration
guide suggests.
There were lots of GtkGrids, so the diff is particularly
horrendous. Sorry.
This needs serious testing before landing.
This has the side effect of allowing these pages to be shorter - the hidden
widgets forced the visible widgets to have a minimum height. If the old
behaviour is desired then this requires this to be fixed using a better
method.
Firewalld is a Fedora-only daemon, and it doesn't integrate all that
well with Fedora Workstation, the version of Fedora that uses GNOME, so
remove the support.
In Fedora Workstation, firewalld only ever supports one zone, as the
other ones are badly defined, and not translatable or translated.
This code is fairly independent of the rest, and we don't want
net-device-wifi.c to become too massive and unmaintainable.
The code in connection-editor/ is fairly similar to
nm-connection-editor, with some simplification because we
currently only edit wireless connections.
The code in wireless-security/ is almost a straight copy
of the same code in nm-connection-editor, with some changes
to the .ui files to make them fit better in the new design.
