If device existed previously, it has been removed before calling of
btd_event_remote_name(), so this just update storage cache and name
property change of device object is not emitted.
Mgmt interface allows to change connectable and discoverable adapter
status even if the adapter is off. So both status are changed during
adapter init.
Remove on_mode from btd_adapter_get_mode(), as it is no more used.
Update src/mgmt.c and plugins/neard.c
Most uses of adapter_get_address were in form of:
bdaddr_t addr;
adapter_get_address(adapter, &addr);
foo(&addr);
Changing it to getter makes code simpler and avoid number of not
needed memcpy.
This function is used by neard to request data to be transmitted over
OOB channel. It also allows neard to provide data to be used in OOB
pairing without initializing pairing it self.
