Keith Whyte c27bc90ae6 Vty: Fixup config shown/written from vty
This commit fixes the following errors:
Missing timeout param for mslookup.
Fails to start reading a written config if an msc node
is configured in the mslookup server.
Places the individual msc node services in the
top-level wildcard node due to incorrect indentation.

* Add missing timeout param.
* Add missing "ipa-name" part to mslookup-server-msc section.
* Add one extra space indentation for msc services.

This commit also adds a DEFINE for the default timeout value.

Harald Welte 7a4765325d Support building with -Werror=strict-prototypes / -Werror=old-style-definition
Unfortunately "-std=c99" is not sufficient to make gcc ignore code that
uses constructs of earlier C standards, which were abandoned in C99.

See for
some related discussion.

Neels Hofmeyr 76328bdc91 D-GSM 3/n: implement roaming by mslookup in osmo-hlr
Add mslookup client to find remote home HLRs of unknown IMSIs, and
proxy/forward GSUP for those to the right remote HLR instances.

Add remote_hlr.c to manage one GSUP client per remote HLR GSUP address.

Add proxy.c to keep state about remotely handled IMSIs (remote GSUP address,
MSISDN, and probably more in future patches).  The mslookup_server that
determines whether a given MSISDN is attached locally now also needs to look in
the proxy record: it is always the osmo-hlr immediately peering for the MSC
that should respond to mslookup service address queries like SIP and SMPP.
(Only gsup.hlr service is always answered by the home HLR.)

Add dgsm.c to set up an mdns mslookup client, ask for IMSI homes, and to decide
which GSUP is handled locally and which needs to go to a remote HLR.

Add full VTY config and VTY tests.

For a detailed overview of the D-GSM and mslookup related files, please see the
elaborate comment at the top of mslookup.c (already added in an earlier patch).
