This conservative fixes tries to fetch info from both
opal_dstore_nonpeer and opal_dstore_peer.
This is required is task A spawns tasks B and C.
B was previously unable to find info from C, this caused locality
info not being set and a hang in coll/ml init.
no CMR is required since v1.8 uses a unique dstore

this commit is a temporary fix that OBJ_RELEASE the endpoint as much as needed.

Revamp the ORTE global data structures to reduce memory footprint and add new features. Add ability to control/set cpu frequency, though this can only be done if the sys admin has setup the system to support it (or you run as root).

We were still leaking 1) file descriptors for data files, and 2) some
control files. I fixed both of these leaks and everything is looking
good. This should fix the bug where we are running out of file
descriptors when running the loop_spawn test. I also too the
opportunity to refactor the code a bit to make the mapping/unmapping
simpler. This should help avoid these sorts of issues in the future.
Depends on #4678

Per Ralph :
"I noticed that we are incrementing and decrementing the opal_progress_event state.
However, this no longer has any impact whatsoever on the RML as that is running in
the independent ORTE event thread. So all this actually does is impact the MPI layer
by adding an unnecessary overhead."
Thanks Ralph for pointing this :-)

This commit is a slightly better workaround to prevent mesages of
the form:
[unset]:_pmi_alps_get_apid:alps_app_lli_put_request failed
[unset]:_pmi_alps_get_appLayout:pmi_alps_get_apid returned with error: Bad file descriptor
It works by completely disabling PMI in the application process when using
mpirun. This should not be an issue for any apps.

Now that the infrastructure is calling BTL del_procs() before the BTL
finalize(), the usnic BTL had to re-order some of its teardown
sequence to avoid assert() failing.
This is part of a larger conversation involving #4669. Since
MPI_FINALIZE and MPI_COMM_DISCONNECT currently use an
oob/grpcomm-based barrier, the usnic BTL can ''absolutely know'' that
these endpoints and procs will no longer be used. If the ORTE DPM
goes back to a PML-based barrier, the usnic BTL will need to grow more
complex teardown semantics (a la TCP socket FIN/ACK/FIN_WAIT states).

to be based on grpcomm (i.e., an out-of-band based barrier) rather
than the simplistic PML-based barrier that it currently uses.
This is pending a larger discussion with Nathan and George, but it
will allow the usnic BTL to stop assert()-failing in light of the
recent del_procs() change.
