Store GPRS MOs directly under BTS SiteMgr object
The only real 1-1 relationship between BTS NM objects is the one between GPRS Cell and BTS (which is actually a BTS cell). In our current osmo-bts implementation we don't care much since we only handle 1-cell BTSses, but let's make the data structure organization more generic. Implementation notes: The gsm_bts_sm is moved to its own file, APIs to allocate are added and the new public object is hooked correctly in the allocation process of osmo-bsc.
