Make power control widget be more responsive. Fix StrictMode violations.
Also use new location providers changed broadcast intent, and fix a bug
introduced in Froyo where we stopped observing the SYSTEM_CLOSE_DIALOGS
intent so we fell out of sync (more often) with the sync settings.
Now even responsive during the boot I/O storm! (except for toggling
brightness, which still does disk writes from the UI thread...)
