g_dbus_emit_property_changed doesn't send dbus signal immediately. Instead
it stores changed properties, and schedule signal to be send at
g_iddle_add. Additionally, if this method is called few times for some
property, only last value will be sent in property changed signal.
If remote device sends lots of notifications, they're all scheduled to be
notified using this method. This might result in some notifications being
lost.
This patch adds new method, that can immediately send property changed
signal, instead of sheduling it for nearest iddle moment.
