Auto-connect Bluetooth device only when user initiates pairing.

Fix bug 2271901: do not auto-connect to services on a BT device
when pairing was initiated by the device (e.g. for OPP file transfer).

Also corrected some typos and removed an unneeded lock object in
LocalBluetoothManager (synchronize on .class object instead, like
android.bluetooth.BluetoothDevice.getService() does).
