Thomas Zimmermann 25c352176c Bug 1153796: Share BluetoothInterface.{cpp,h} between Bluetooth v1 and v2, r=btian
With this patch, Bluetooth v1 and v2 share the same interfaces classes
for their backend code. Bluetooth v1 doesn't yet support GATT, so the
GATT interfaces are still not implemented.

The patch also fixes the GATT-specific classes to compile under recent GCC
versions 4.8 and later, which are used with Android L.

The patch also preserves the prefered backend for each version. Bluetooth
v1 defaults to 'bluetoothd,' v2 defaults to 'bluedroid.'
