Ralph Castain eece9f88f0 Fix a bug in the way we computed local_rank. This needs to be the local_rank -among my job peers- on a node.

We were mistakenly computing the local_rank across -all- jobs with procs on that node. While the two definitions are equivalent for an initial launch, comm_spawn'd procs would get the wrong local_rank. In particular, there would not be a local_rank=0 proc in the comm_spawn'd job on any node that was shared with the initial job.

This commit was SVN r18263.

Bring some sanity to the exit code returned by mpirun. Ensure that we provide a non-zero code if something goes wrong, including someone exiting after calling mpi_init without calling mpi_finalize.
