Desired for MPI support

when looking for CR_CORE_MEMORY)

If the pre_run API fails (after job allocation has been made), then
  release the resource and requeue/hold the job

The "paths" API is returning an error in some cases when it should
not, this adds logic to test the response string and process the
paths file produced when it actually does work.

bug 1911

Remove our work around for a bug in the Cray API that has recently
  been fixed.
Improve error message for root jobs trying to use DW.

One API was fixed, another broke (work around for one removed, added
for the other API).

This fixes some race conditions with threads (e.g. a buffer is found
to be missing before the thread tearing it down records the operation
has completed).

If the show_sessions/instances/configuration API returns an error
code, test its contents before trying to parse it since it may
contain some genuine error message. This provides a better work
around for bug already reported to Cray.

This change is already logged in the NEWS for v14.11.10

Do not use full path for true utility in testsuite. Its location
differ across systems (/bin/true on Linux and /usr/bin/true on BSD).

Required to remove stale PMI2 sockets from /tmp

Previous logic would set the avail_node_bitmap when
a node was powered down, even if the initial state was
DOWN or DRAINED. This made the node available for allocation
to a job, which we don't want until the DOWN or DRAIN
state is cleared.
