Over the course of time, usage of static ports got corrupted in several places, the "parent" info got incorrectly reset, etc. So correct all that and get the regex-based wireup going again. Also, don't pass node lists if static ports aren't enabled - they are of no value to the orted and just create the possibility of overly-long cmd lines. This commit was SVN r24860.
