cscn: implement integrity protection
Upon authentication response, initiate integrity protection for Iu by sending a
Security Mode Command (IK), with hardcoded auth tuple so far.
Implement RANAP event handling to receive Security Mode Complete message,
adding stubs for the other events; in new files osmo-cscn/iucs_ranap.[hc] to
keep RANAP dependencies separate, and particularly out of libmsc.
Upon receiving Security Mode Complete, call the security operation callback
(conn->sec_operation->cb) to complete the Location Update.
Introduce enum integrity_protection_state constants to indicate integrity
protection, record in gsm_subscriber_conn.iu.integrity_protection.
Make subscr_conn_lookup_iu() non-static and declare in iu_cs.h to be able to
call from iucs_ranap.c's Security Mode Complete event.
Implement dummy iu_tx_sec_mode_cmd() to allow tests to build without RANAP
dependencies.
In cscn_main.c, call iucs_rx_ranap_event(), to populate the struct gsm_network
struct with cscn_network explicitly (don't share cscn_network across
compilation scopes because it's ugly).
