Victoria Lease b711d57ca4 Multiuser love for LocationManager
LocationManagerService now keeps track of the current user ID and
denies location requests made by all but the foreground user.

Additionally, location settings are now user-specific, rather than
global to the device. Location provider services now run as specific
users, and when the device's foreground user changes, we rebind to
appropriately-owned providers.
