QLowEnergyController_bluez now responds to server requests.
The bluez implementation of QLowEnergyController now responds to
requests with a "Request not supported" message, instead of ignoring it.
If such requests are ignored, the remote will close the connection after
30 seconds, according to the bluetooth ATT specification.
