WIP: OM2000: Full state machine implementation using osmo_fsm

Our existing OM2000 code for initializing all Managed Objects of a BTS
at startup was never complete.  Rather than trying to fix the old-style
code, introudce a hierarchy of osmo_fsm's reflecting the full protocol
hand-shake and sequence of bringing up the individual MO's.

If this works out well, it mihgt make sense to convert the TS 12.21 OML
code for other BTS models, too.
