Subject: [PATCH] ActivityThread: Avoid creating duplicate handlers and reuse
 mH

sMainThreadHandler is used for notification of changes in
SharedPreferences and refers to a new instance of Handler instead
of the existing instance, mH, of the ActivityThread. Fix to reuse
existing handlers associated with main looper.
