Pairing methods in QBluetoothLocalDevice doesn't work on OS X / iOS

QBluetoothDeviceInfo has additional to the method address() a method deviceUuid() to make Apple happy.

The pairing related methods in QBluetoothLocalDevice (e.g. requestPairing(), pairingStatus(), pairingFinished()) are missing such a workaround, i.e. they are essentially not usable with iOS / OS X (or did I do something wrong?).

Furthermore, the requestPairing() method seems to have a bug on iOS. Calling this method with an (invalid?) QBluetoothAddress doesn't emit PairingError, as it is correctly done on OS X.
