Fixes#15892
* idl/evolution-calendar.idl: added notifyErrorOccurred method to
the Listener interface, so that backends can notify clients of errors
that can't be reported otherwise.
* pcs/cal.[ch] (cal_notify_error): new function.
* pcs/cal-backend-file.c (save): made to save to temporary file and
then moved to the correct file, so that we don't lose any data if
there's a problem while saving.
(notify_error): new function for notifying error messages to clients.
* cal-client/cal-listener.[ch]: added new callback function for getting
error messages from backends.
(impl_notifyErrorOccurred): new method implementation.
(cal_listener_class_init): initialize new epv member.
(cal_listener_init, cal_listener_destroy, cal_listener_construct,
cal_listener_new): initialize new function pointer.
* cal-client/cal-client.[ch]: adapted to changes in CalListener class.
(cal_client_class_init): added "backend_error" signal to CalClient class.
(backend_error_cb): callback for "error_occurred" signal on the CalListener,
which just emits the "backend_error" signal of CalClient.
* gui/gnome-cal.c (gnome_calendar_construct): connect to "backend_error"
signal on the CalClient's we create.
(backend_error_cb): display error message on error from backend.
* gui/e-tasks.c: likewise.
