Change the priority of comm_failure and job_termination events to ensure we process final messages prior to terminating. Check for termination conditions when processing proc termination events as we may order proc termination when the daemon gets an exit command, but we can't see the proc actually terminate until we get out of that message event.
Jeff: probably easiest to review this by testing. I tested it under both Slurm and rsh on v1.7.5 as well as trunk

Modify the check_complete code so it finds the first non-zero exit status (i.e., the one from the lowest rank) in a job that terminates normally, and sets the mpirun exit code to that status.
