• starts a new devel branch
• added a generic test driver for RainerScript plus some test cases to the testbench
• added a small diagnostic tool to obtain result of gethostname() API
• imported all changes from 3.18.1 until today (some quite important, see below)

Changes merged in from 3.18.1 include, among others:

• bugfix: potential segfault in creating message mutex in non-direct queue mode. rsyslogd segfaults on freeeBSD 7.0 (an potentially other platforms) if an action queue is running in any other mode than non-direct. The same problem can potentially be triggered by some main message queue settings. In any case, it will manifest during rsylog's startup. It is unlikely to happen after a successful startup (the only window of exposure may be a relatively seldom executed action running in queued mode). This has been corrected. Thank to HKS for point out the problem.
• bugfix: remove PRI part from kernel message if it is present Thanks to Michael Biebl for reporting this bug
• bugfix: mark messages were not correctly written to text log files the markmessageinterval was not correctly propagated to all places where it was needed. This resulted in rsyslog using the default (20 minutes) in some code pathes, what looked to the user like mark messages were never written.
