some current patches blocking others

Would like to mention, since it's hard to see the sequence of patches in gerrit. I have a series of osmo-hlr patches ready for commit, but others preceding them still need review: https://gerrit.osmocom.org/#/c/4305/ https://gerrit.osmocom.org/#/c/4273/ https://gerrit.osmocom.org/#/c/4275/ ...whenever you get a chance is fine, thx! ~N
