wip: Correct return values of signal handlers
I verified using the following semantic patch that there are no signals that return a value in File
Roller, and very little in GLib and GTK:
https://gitlab.gnome.org/jtojnar/glib-refactoring/-/blob/5d70945511ce1f924f2f3eae59cb382bf39caeb7/patches/find-non-void-signals.cocci
Then I ran this semantic patch to set return values of all handlers to void:
https://gitlab.gnome.org/jtojnar/glib-refactoring/-/blob/d0451e42055daef4de72354f110256aeab8dfd89/patches/voidize-signal-handlers.cocci
⚠ Still need to verify with Tartan that there were no false positives.
