move ran_conn declarations to new ran_conn.h
With the dawn of inter-BSC,MSC handover, adopting the MSC-A,-I,-T roles from
3GPP TS 49.008, the RAN connection shall soon be a neatly separated corner of
osmo-msc, so gravitate ran_conn decarations to files of matching name.
Also, the current chaos of API defined in files with mismatching/meaningless
names drives me crazy.
