98e98ce2c5 * opal_atomic_trylock is documented to return 0 if the lock was acquired,
1 otherwise.  It was doing the opposite, so this patch fixes the
  return values.  All uses (all in ORTE) used the actual return values,
  not the documented values, so fix them as well.

b42ccc89b8 Although this didn't solve the earlier termination problem, the code will be required once we get connection terminations properly detected. If a daemon (or HNP) is trying to terminate, then we need to check for termination conditions whenever a route is lost - when all child connections are gone, then we are free to finalize.

8ac35a8496 Fully enable the monitoring of memory usage and automatic termination of memory hogs when limits are reached. Improve the efficiency of the sensor system so we don't multiply sample the resource usage if multiple modules are active. Ensure we output the proc error summary when we abnormally terminate.

e1ba09ad51 Add a resilience to ORTE. Allows the runtime to continue after a process (or
ORTED) failure. Note that more work will be necessary to allow the MPI layer to
take advantage of this.

3a28556472 Expand our handling of non-zero exit status. If a process exits with non-zero status, pass that info along to the user in case it means something to them, even if the process also exited without calling MPI_Finalize. If the process calls MPI_Abort, that trumps the exit status question.
Provide a new MCA param that allows the user to direct that we abort the job once a process exits with non-zero status. No recovery is allowed in such cases to avoid trying to restart a process that has already exited MPI.

12cd07c9a9 Start reducing our dependency on the event library by removing at least one instance where we use it to redirect the program counter. Rolf reported occasional hangs of mpirun in very specific circumstances after all daemons were done. A review of MTT results indicates this may have been happening more generally in a small fraction of cases.
The problem was tracked to use of the grpcomm.onesided_barrier to control daemon/mpirun termination. This relied on messaging -and- required that the program counter jump from the errmgr back to grpcomm. On rare occasions, this jump did not occur, causing mpirun to hang.

This patch looks more invasive than it is - most of the affected files simply had one or two lines removed. The essence of the change is:

* pulled the job_complete and quit routines out of orterun and orted_main and put them in a common place

* modified the errmgr to directly call the new routines when termination is detected

* removed the grpcomm.onesided_barrier and its associated RML tag

* add a new "num_routes" API to the routed framework that reports back the number of dependent routes. When route_lost is called, the daemon's list of "children" is checked and adjusted if that route went to a "leaf" in the routing tree

* use connection termination between daemons to track rollup of the daemon tree. Daemons and HNP now terminate once num_routes returns zero

Also picked up in this commit is the addition of a new bool flag to the app_context struct, and increasing the job_control field from 8 to 16 bits. Both trivial.
