Not sure why it was failing in slurmd on smd, but this fixes it

This is to translate the CPU lists in gres.conf to the local
  CPU ID values used by cpuset bitmaps

Previously the test would generate an error if the default partition
  contained less than 3 nodes
bug 1720

Add a new GRES function to return the count of elements of a specific
  GRES name
Add a new GRES funtion to reset environment variables based upon the
  GRES which are usable from the CPUs to which a task is bound

Revert "Change cpu_time measurements from uint32_t to double. This gives more accurate cpu utilization when sampling at 1 second rate. Otherwise cpu utilization will be only 100 or 0. With this change it can be any value between 0 and 100."

This reverts commit eaf8e1a2.

switch/cray: Refine logic to set PMI_CRAY_NO_SMP_ENV environment variable.
Rather than testing for the task distribution option, test the actual
task IDs to see fi they are monotonically increasing across all nodes.
Based upon idea from Brian Gilmer (Cray).

Improve cpu profiling values

Change cpu_time measurements from uint32_t to double. This gives more accurate cpu utilization when sampling at 1 second rate. Otherwise cpu utilization will be only 100 or 0. With this change it can be any value between 0 and 100.

Add srun --accel-bind option to control how tasks are bound to GPUs and NIC
    Generic RESources (GRES).
Based in part upon work by Matthieu Ospici (ATOS).
gres/nic plugin modified to set OMPI_MCA_btl_openib_if_include environment
    variable based upon allocated devices (usable with OpenMPI and Melanox).
Reset GRES env vars after task affinity set

local _get_int functions.
