Change subject: Add SGs Interface
......................................................................


Patch Set 29:

feedback on some of my initial concerns, which we talked about in person:
TLDR: all of my higher level concerns are addressed and we're good to go.

- paging: the SGs indeed registers the subscriber with the 2G MSC, after which it stays valid in the VLR without a timeout, i.e. without periodic LU being required.

- HLR: the SGs indeed contacts the HLR correctly. After it has registered a subscriber in the VLR including a GSUP LU procedure, it stays in the VLR until an IMSI Detach or until the SGs interface goes down, so a vlr_susbcr_find_*() is indeed sufficient.

- inter-MSC HO: the SGs interface state is already placed in the vlr_subscr struct, hence there will be no need to separate it from the ran_conn in order to keep the SGs at the MSC-A.
