gb: optionally allow nsip packets only from a specific host
When listening for nsip connections is enabled, then every remote
host may send packets. This is useful for an SGSN that serves
multiple PCUs, but contraproductive for a PCU that awaits packets
from a single SGSN.
Add struct members remote_ip, and remote_port to struct gprs_ns_inst,
when set, then the listening end uses connect() to ensure that only
the expected host may send packets.
