bugfix: huge memory leak in queue engine (made rsyslogd unusable in production). Occured if at least one queue was in direct mode (the default for action queues)
imported many performance optimizations from v4-devel (4.5.0)
bugfix: subtle (and usually irrelevant) issue in timout processing timeout could be one second too early if nanoseconds wrapped
set a more sensible timeout for shutdow, now 1.5 seconds to complete processing (this also removes those cases where the shutdown message was not written because the termination happened before it)
numerous enhancements and fixes imported from the v4 branch
