klocwork, help file changes and segfault issue resolved in job launch code.

Following are the changes in this branch

1) klocwork reported issues in job launch code (orun.c, orcmsd.c, sst_orcmsd.c)
2) Changes related to help file lookup for orcmsd tool
3) Fixing a segfault issue  with the mca destructor for the newly added mca parameter in the sst_orcmsd_components file (orcm_node_regex, orcm_base_jobid, orcm_base_vpid).
Is there some reason to create these synonyms? I see nothing wrong with leaving the param as "sst_orcmsd_node_regex". It would be more accurate and in keeping with the normal MCA param convention. We only use synonyms for backward compatibility, and that isn't the case here.
