libosmo-sccp: branch sysmocom/iu

I've created a branch sysmocom/iu based on the laforge/wip branch currently used for 3G dev. I've added minor commits and rebased the branch onto current master. The tendency should be to use sysmocom/iu in libosmo-sccp for 3G development (and coverity @Holger). ~Neels -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Holger Freyther, Harald Welte
