This can lead to have a SMC re-transmission before the first RLL
Establish Request has timed out. Reduce the RLL timeout. GSM 08.58
does not specify a timeout so right now I just reduce it to seven
seconds.
libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]
