[MERGED] openbsc[master]: Make si2q scheduling optional

Holger Freyther has submitted this change and it was merged. Change subject: Make si2q scheduling optional ...................................................................... Make si2q scheduling optional Previously si2quater SI messages were always scheduled. Check for neighbor configuration and only schedule si2q when necessary. Add corresponding unit test.
