bsc: inter-BSC HO: add TC_ho_out_of_this_bsc, TC_ho_into_this_bsc
Add f_gen_handover_req() like f_gen_ass_req(), to match AoIP or SCCPlite requirements. For incoming HO, MSC_ConnHdlr needs to know the SCCP addresses to expect the incoming SCCP Connection from MSC to BSC. Add 'handover' section to TestHdlrParams, and pass in the addresses from test_CT via that. In osmo-bsc.cfg, add a remote neighbor config, so that the VTY command 'handover any to arfcn 123 bsic any' can trigger an outgoing inter-BSC HO. Add various BSSMAP handover templates to BSSMAP_Templates.ttcn. Add RR Ho Command template to L3_Templates.ttcn. Move ts_BSSAP_Conn_Req() from msc/BSC_ConnectionHandler.ttcn to library/BSSMAP_Emulation.ttcn, so we can also model an SCCP Connection Request in BSC_Tests.ttcn (this time from MSC to BSC). Add the two new tests to bsc/expected-results.xml. Related: OS#2283 Change-Id: Id22852d4be7f127d827e7a8beeec55db27c07f03
