Bluetooth Low Energy search should have no timeout

When running a BLE device search using QBluetoothDeviceDiscoveryAgent, 10 seconds after we call start(), search is stopped automatically and finish() is emited.

This is due to a timeout setup by src\bluetooth\qbluetoothdevicediscoveryagent_android.cpp, line 273.

The thing is that the device we are trying to find may not be found within 10sec, so only the end user/developer should decide when to stop the discovery agent search. Timeout feature is nice, but should be optional (why not an optional parameter to the start() slot). I struggled hours to understand what was going on and why my device was not found....it was just because Qt was not searching it anymore...
