gprs_ns2_sns: Support for SGSN-side IP-SNS

This adds the core functionality of implementing the SGSN-side of IP-SNS
inside a new FSM.  The SGSN-side FSM shares states, events, structures
and code with the BSS-side whenever possible.

Note that this commit does not yet use the SGSN-side FSM, that is part
of subsequent commits.

Closes: OS#3373
