reinvent connection_for_subscr() and move to libmsc
Implement connection_for_subscr() from a completely different angle: instead of looking up lchans in bts structs, look up the subscriber in the global list of gsm_subscriber_connection. static lchan_find() is thus obsoleted. All callers of connection_for_subscr() live in libmsc, so move to libmsc. The move and edit are done in a single commit since the old and new implementation have nothing in common. Future: osmo-cscn will use this, without bts being present. Remove implementation of connection_for_subscr() from channel_test.c -- it is possible that the abort() in there was intended for a regression test, but actually it seems the implementation was merely added for linking reasons, and the abort() added to guard against the NULL return value: no comment nor the commit log indicate that the abort() is test critical; the addition was the only change in channel_test.c for that commit; at the same time a connection_for_subscr() call was added in libmsc.
