Callers with INTERACT_ACROSS_USERS_FULL permission can now observe content for a given user's view (and can notify content uri changes targeted to a specific user). An observer watching for UserHandle.USER_ALL will see all notifications for the given uri across all users; similarly, a notifier who specifies USER_ALL will broadcast the change to all observers across all users. The API handles both USER_ALL or USER_CURRENT, and explicitly forbids any other "pseudouser" designations. This CL also revs the Settings provider to notify with USER_ALL for changes to global settings, and with only the affected user's handle for all other changes.
