Port QBluetoothServiceInfo and QBluetoothServiceDiscoveryAgent to OS X.

QBluetoothServiceInfo and QBluetoothServiceDiscoveryAgent - version for
OS X (IOBluetooth-based).

Update 0: initial dummy version + mods to enable this new classes to be built
          with qtconnectivity.
Update 1: SDP query + initial implementation of a services discovery agent.
Update 2: aux functions to "parse" a service records once I got it.
Update 3: extract services UUIDs on a discovered device, if any.
Update 4: refactor
Update 5: "fix" asserts
Update 6: more asserts fixed.
Update 7: add the ability to stop SDP query (to be tested!!!)
Update 8: mods as suggested in review.
Update 9: no reason to check the size of discoveredDevices after 'clear' call.
Update 10: set an error and error description only if it's a 'singleDevice'.
Update 11: fix private header (_p suffix).
Update 12: on 10.7 (with quite old clang) there is no 'subscript operator'
           syntax for NSDictionary.
