Ralph Castain 011403c04a Fix a number of issues, some of which have lingered for a long time: 
* provide a more reliable way of determining that a process is a singleton by leveraging the schizo framework. Add new components for slurm, alps, and orte to detect when we are in a managed environment, and if we have been launched by mpirun or a native launcher. Set the correct envars to control ess and pmix selection in each case.

* change the relative priority of the pmix120 and pmix112 components to make pmix120 the default

* fix singleton comm-spawn by correctly setting the num_apps field of the orte_job_t created by the daemon - this fixes a segfault in register_nspace on newly created daemons

* ensure orterun doesn't propagate any ess or pmix directives in its environment

* Cleanup a few valgrind issues and memory leaks

* Fix a race condition that prevented the client from completing notification registrations (missing thread shift)

* Ensure the shizo/alps component detects launch by mpirun

/**** DEBUGGER CODE ****/
/*
* Debugger support for orterun
*
* We interpret the MPICH debugger interface as follows:
*
* a) The launcher
* - spawns the other processes,
* - fills in the table MPIR_proctable, and sets MPIR_proctable_size
* - sets MPIR_debug_state to MPIR_DEBUG_SPAWNED ( = 1)
* - calls MPIR_Breakpoint() which the debugger will have a
* breakpoint on.
*
* b) Applications start and then spin until MPIR_debug_gate is set
* non-zero by the debugger.
*
* This file implements (a).
*
**************************************************************************
*
* Note that we have presently tested both TotalView and DDT parallel
* debuggers. They both nominally subscribe to the Etnus attaching
* interface, but there are differences between the two.
*
* TotalView: user launches "totalview mpirun -a ...<mpirun args>...".
* TV launches mpirun. mpirun launches the application and then calls
* MPIR_Breakpoint(). This is the signal to TV that it's a parallel
* MPI job. TV then reads the proctable in mpirun and attaches itself
* to all the processes (it takes care of launching itself on the
* remote nodes). Upon attaching to all the MPI processes, the
* variable MPIR_being_debugged is set to 1. When it has finished
* attaching itself to all the MPI processes that it wants to,
* MPIR_Breakpoint() returns.
*
* DDT: user launches "ddt bin -np X <mpi app name>". DDT fork/exec's
* mpirun to launch ddt-debugger on the back-end nodes via "mpirun -np
* X ddt-debugger" (not the lack of other arguments -- we can't pass
* anything to mpirun). This app will eventually fork/exec the MPI
* app. DDT does not current set MPIR_being_debugged in the MPI app.
*
**************************************************************************
*
* We support two ways of waiting for attaching debuggers. The
* implementation spans this file and ompi/debuggers/ompi_debuggers.c.
*
* 1. If using orterun: MPI processes will have the
* orte_in_parallel_debugger MCA param set to true (because not all
* debuggers consistently set MPIR_being_debugged in both the launcher
* and in the MPI procs). The HNP will call MPIR_Breakpoint() and
* then RML send a message to VPID 0 (MCW rank 0) when it returns
* (MPIR_Breakpoint() doesn't return until the debugger has attached
* to all relevant processes). Meanwhile, VPID 0 blocks waiting for
* the RML message. All other VPIDs immediately call the grpcomm
* barrier (and therefore block until the debugger attaches). Once
* VPID 0 receives the RML message, we know that the debugger has
* attached to all processes that it cares about, and VPID 0 then
* joins the grpcomm barrier, allowing the job to continue. This
* scheme has the side effect of nicely supporting partial attaches by
* parallel debuggers (i.e., attaching to only some of the MPI
* processes; not necessarily all of them).
*
* 2. If not using orterun: in this case, we know that there will not be an RML message
* sent to VPID 0. So we have to look for a magic environment
* variable from the launcher to know if the jobs will be attached by
* a debugger (e.g., set by yod, srun, ...etc.), and if so, spin on
* MPIR_debug_gate. These environment variable names must be
* hard-coded in the OMPI layer (see ompi/debuggers/ompi_debuggers.c).
