Bring a new device into the PAN network.  The Control() call will complete as
soon as the PAN agent has started the process, so it may be several seconds
before the device is addressable.  It is also possible for the connection
attempt to fail even if the Control() method returns KErrNone, due to the
actual processing occuring asynchronously.

@code
RConnection connection;
TBTDevAddr remoteDeviceToAdd;
...
<Connect RConnection object, and find the remote device to add to the PAN>
...
TPtr8 ptr = remoteDeviceToAdd.Des();
User::LeaveIfError(connection.Control(KCOLAgent, KCOAgentPanConnectDevice, ptr));
@endcode

The use of a temporary TPtr is safe, as the Control method is synchronous.

Return a list of connected devices.  If the buffer supplied is too small to
hold all of the device addresses, as many as will fit will be returned.  The
descriptor length will be adjusted to reflect the total connected device count.

@note Devices which are still in the process of connecting to the PAN network
will not be included.
