libmsc: fix: properly initialize the SGs server
It was observed that the SGs server is started before
the actual VTY configuration is parsed. For example:
sgs
local-port 9999
local-ip 127.0.0.1
vlr-name vlr.example.net
produces the following debug output:
<0011> sgs_server.c:185 SGs socket bound to r=NULL<->l=0.0.0.0:29118
DLSS7 NOTICE <001e> osmo_ss7.c:1284 0: ASP Restart for server not implemented yet!
DSGS NOTICE <0011> sgs_server.c:185 SGs socket bound to r=NULL<->l=0.0.0.0:9999
DSGS NOTICE <0011> sgs_server.c:185 SGs socket bound to r=NULL<->l=127.0.0.1:9999
DMNCC DEBUG <0004> msc_main.c:604 Using internal MNCC handler.
The first startup is triggered by sgs_iface_init(), before reading
the VTY configuration, so the logging style is different. The next
two calls to sgs_server_open() are triggered during reading of the
VTY configuration by cfg_sgs_local_port() and cfg_sgs_local_ip().
Let's avoid starting the SGs server three times, and do it once,
after the VTY configuration is parsed. Also, keep the possibility
to change the binding parameters at run-time.
