From 73952e3ab4629076c67fd64351d3d0649d75a426 Mon Sep 17 00:00:00 2001
From: Harald Welte <laforge@gnumonks.org>
Date: Sat, 16 Jun 2012 14:59:56 +0800
Subject: split libgb into a separate library for outside use

This also removes the dependency to osmo_sock() inside libcommon and
replaces it with osmo_sock_* from libosmocore
