Allow sending of bulk Uri change notifications.

Browse Source 
MediaProvider makes heavy use of Uri change notifications, which
currently need to be delivered one at a time through the Binder
interface.  To optimize this, allow callers to provide a collection
of multiple Uris to notify with a single Binder call.
