Hello Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/1521

to look at the new patch set (#2).

Remove code duplication

Use functions and definitions from libosmocore. Requires libosmocore
with commits with I9c3bc15662949654e7bba6aad5488c69ee7d0c45 and
Ieaaaed19da9c069fe451faa53d24c5b84d7d5615 IDs.
