Connectivity is becoming a mainline module in S, so
ConnectivityManager hidden symbols can not be used for outside
components. Besides, most Tethering relevant methods or variables
on CM are migrated to TetheringManager. So replace all these
methods or variables from ConnectivityManager to TetheringManager
on Settings.

Bluetooth, USB and Wifi Disable tether preferences will turn on/off that
type of tethering interface instantly without storing it into
SharedPreferences. They are listening to TetherEnabler to update their
state.
Refactored to remove dependancy on SharedPreferences.
