add libosmo-mslookup abstract client
mslookup is a key concept in Distributed GSM, which allows querying the current
location of a subscriber in a number of cooperating but independent core
network sites, by arbitrary service names and by MSISDN/IMSI.
Add the abstract mslookup client library. An actual lookup method (besides
mslookup_client_fake.c) is added in a subsequent patch.
For a detailed overview of this and upcoming patches, please see the elaborate
comment at the top of mslookup.c.
Add as separate library, libosmo-mslookup, to allow adding D-GSM capability to
arbitrary client programs.
osmo-hlr will be the only mslookup server implementation, added in a subsequent
patch.
osmo-hlr itself will also use this library and act as an mslookup client, when
requesting the home HLR for locally unknown IMSIs.
