We already have MSC connection stat items, but for hysterical raisins
there are separate such stats for each MSC. Hence we have N connection
counters, each being either 0 or 1, for a single MSC.
Add a new stat counting the *overall* MSCs that are connected,
and one indicating the total number of configured MSCs.

Instead of having static const structs in header files (which end up
duplicated in each and every compile unit!), have one .c file with the
rate_ctr and stat_item descriptions.
