This uncovered a bug in name watching if the name wasn't activatable.
Also provoked the need for on_connection variants of g_bus_watch_name
(added g_bus_watch_proxy's variant as well).
Things compile and the test-suite passes. Still need to hook up
gio.symbols and docs. There are still a bunch of TODOs left in the
sources that needs to be addressed.
