MessageQueue: integrate with glib main loop

Browse Source 
Adds a special treatment for the main Looper to not block in java code,
but instead return to glib managed thread loop. Timeouts in the mainloop
are now handled using g_timeout_add_full().

Also defer Activity construction, so that every thing is set up properly
when the constructor runs.
