One merge for Seth:
BIT-1177 SumStats dynamic updates do not work in cluster mode
One cleanup for Seth (or anybody else I guess)
BIT-1171 misc/app-stats/main.bro broken for a few sites
One fix for Matthias:
BIT-1140 Bloomfilter hashing problem
Test cases missing for Vlad:
BIT-1129 RADIUS Protocol Analyzer
Two documentation tickets for Daniel:
BIT-1186 Improve cluster configuration documentation
BIT-845 PF_RING+DNA 0
If anybody else is still planing something for 2.3, please open a
