socket: Reimplement osmo_sock_init2_multiaddr()

This is an attempt to fix several downsides of current
osmo_sock_init2_multiaddr() API, mainly the requirement to pass an explicit
local address (!NULL). It also now works fine if OSMO_SOCK_F_BIND flag
is not used.

This reimplementation is based on the follwing logic:
- If caller passed family=AF_INET or family=AF_INET6, that same family
  is used and kernel will fail if something is wrong.
- If caller passes family=AF_UNSPEC, the function will try to find the
  required family to create the socket. The decision is taken on the
assumption that an AF_INET6 socket can handle both AF_INET6 and AF_INET
addresses (through v4v6 mapping). Hence, if any of the addresses in the
local or remote set of addresses resolves through getaddrinfo() to an
IPv6 address, then AF_INET6 is used; AF_INET is used otherwise.

libosmocore - set of Osmocom core libraries

This repository contains a set of C-language libraries that form the core infrastructure of many Osmocom Open Source Mobile Communications projects.

Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.

There is no clear scope of it. We simply move all shared code between the various Osmocom projects in this library to avoid code duplication.

The libosmocore.git repository build multiple libraries:

  • libosmocore contains some general-purpose functions like select-loop abstraction, message buffers, timers, linked lists
  • libosmovty contains routines related to the interactive command-line interface called VTY
  • libosmogsm contains definitions and helper code related to GSM protocols
  • libosmoctrl contains a shared implementation of the Osmocom control interface
  • libosmogb contains an implementation of the Gb interface with its NS/BSSGP protocols
  • libosmocodec contains an implementation of GSM voice codecs
  • libosmocoding contains an implementation of GSM channel coding
  • libosmosim contains infrastructure to interface SIM/UICC/USIM cards
