introduce '-2' commandline option for second BS-11

Using this option, you can use two BS-11 connected to the same E1
link.  The first BS-11 needs to have BPORT0 and BPORT1 objects created with E1
Line Configuration attribute "multi-drop".  The second BS-11 is configured with
only BPORT0 in star configuration, and needs to have the OML signalling on TS6
instead of TS1.  Also, a kernel patch providing a second virtual E1 interface
is needed.
