This is a correction to commit 1eb32d90
so the select/cray plugin can be built on non-Cray system (for testing).
bug 1587

GRES counters changed in v15.08 from 32- to 64-bit.

slurmd was logging:
"Error reading step 2031886.0 memory limits" (with various job/step IDs)
because it was treating SLURM_SUCCESS as an error rather than SLURM_ERROR
bug 1589

Add logging of premature EOF

Disable changes to GRES count while jobs are running on the node.
Previous logic could clear GRES count data and generate counter
underflow then when attemtping to deallocate the job's resources
(including future job terminations when computing when and where
pending jobs will start as part of backfill scheduling logic).

if many steps/jobs finish at once.

* Add "--thread-spec" option to salloc, sbatch and srun commands. This is
  the count of threads reserved for system use per node.
* Add ability for scontrol to get/set job ThreadSpec
* sivew: Add job ThreadSpec field to get/set
* Modify select/cons_res to manage job allocations while leaving specialized
  threads for system use.
* core_spec plugins: Fix system task binding logic and logging
* Modify squeue output for thread_spec values
* task/affinity and cgroup: Enhanced task binding logic

added back into the system.

This improves the packing for a configuration of
topology/tree, dragonfly, select/cons_res when specific nodes
are required.

* Add "TopologyParam" configuration parameter. Optional value of "dragonfly"
  is supported.
* select/linear: Add dragonfly topology support
* select/cons_res: Add dragonfly topology support

We plan to duplicate partially duplicate a function and replaced
that function name in logs with "__func__" for better code re-use.

No changes to the test logic
