SMS over GSUP: implement forwarding of MT SMS

When an SMSC tries to deliver an SM to a subscriber, it will send us
an MT-forwardSM.req GSUP message.  We look up the subscriber by IMSI
and see if they are attached to a VLR.  If the subscriber is attached,
we forward the message to the MSC/VLR, otherwise return an error
to the SMSC.
