iu_client: derive local SCCP addr from sccp instance

ranap_iu_init() is passed an sccp instance that has a local primary point code.
Use this primary PC by default as the local address for IuCS and IuPS clients.

Remove the current vty command 'iu local-address point-code PC':
- It is possible that we would like to configure a differing local point code
  at some point; this should then happen via sccp address book entries, not
  parsing PC directly.
- Obtaining the local PC from the SCCP instance makes this command obsolete for
  all setups we're currently aiming at: one local PC per SCCP instance.
- There are vty doc failures in this vty command, which cause osmo-msc and
  osmo-bsc vty test failures; rather than fixing this, let's drop it entirely
  until we see a need for it (and then do it properly with the address book).

Cosmetic: prefix the local static variable with g_* like g_sccp and g_scu and
define it in the same place. No default values are needed anymore, it gets
overwritten in ranap_iu_init().

osmo-iuh - Osmocom Iuh and HNB-GW implementation

This repository contains a C-language implementation of the 3GPP Iuh interface, together with a HNB-GW (Home NodeB Gateway). You can use it to interface Iuh-speaking femtocells/small cells to Iu-speaking MSCs and SGSNs.

It is part of the Osmocom Open Source Mobile Communications project.

Homepage

The official homepage of the project is https://osmocom.org/projects/osmohnbgw/wiki

GIT Repository

You can clone from the official libosmocore.git repository using

git clone git://git.osmocom.org/osmo-iuh.git

There is a cgit interface at http://git.osmocom.org/osmo-iuh/

Documentation

There is currently no documentation beyond the wiki available on the homepage. We would love to see somebody contributing a manual that can be part of the osmo-gsm-manuals suite.

Building

It is generally best to check the wiki for the most up-to-date build instructions.

As external library dependencies, you will need

To bootstrap the build, in the root directory, run:

autoreconf --install

After that, run the usual

./configure [options]
make
[sudo] make install

Using

Note: osmo-iuh just left very active development (December 2015, January 2016), so your mileage may vary.

If you run the 'hnbgw' executable, it will open a listening SCTP socket and wait for incoming Iuh connections. It will accept any HNB-REGISTER-REQUEST, and it will establish Iu (over SUA) connections towards the MSC and SGSN.

Regenerating C code from ASN.1 source

In order to re-generate the C source code from the ASN.1 source, you will need a modified asn1c which has the following features:
