warning fix.

if the pointer is valid

Backup slurmctld will now
1. Not abort due to NULL pointer (needed to move code around on restart)
2. Recover KNL MCDRAM and NUMA modes from state save files if capmc and
   cnselect not available

cray/burst_buffer - Update "instance" parsing to match updated dw_wlm_cli
    output.
bug 3222

No change to logic

requests when they = 1.

What we did was just increase the cpus_per_task to equal the amount of
threads in the core|socket.  This was done with an array to handle
heterogeneous systems.

Bug 2519

Hopefully this will make alterations to this function easier as it doesn't
now consider ntasks_per_*.

Expand the dw_wlm_cli script to include persistent and job-specific
  burst buffers. This script is used by burst_buffer/cray.

Add "FreeSpace" information for each pool to the "scontrol show burstbuffer"
    output. Required changes to the burst_buffer_info_t data structure.
bug 3222

This is a new field and the fix only applies to an emulated burst
  buffer configuration (i.e. dw_wlm_cli script made to look like
  a real DataWarp system)

Change error() to verbose(). New logic is needed to address this issue
   once we know how to determine the KNL MCDRAM size.

cray/burst_buffer - Preserve job ID and don't translate to job array ID
  after slurmctld restart. Prior logic would not set array_task_id to
  NO_VAL, so all job-buffer IDs would be reported in the form
  "JobID=0_0(123)" rather than "JobID=123"

cray/busrt_buffer - Internally track both allocated and unusable space.
    The reported UsedSpace in a pool is now the allocated space (previously was
    unusable space). Base available space on whichever value leaves least free
    space.

Previously disconnected from build system, and most code removed by
commit 0b14a3a7 back on 15.08-pre1.

We don't build on Tru-64, and there are a lot more platform-dependent
pieces of code within Slurm than we've indicated here.

Remove stray Bull logo as well.

Remove stray Bull logo as well.

They're full of dead links, and the plugins are deprecated
(announced at SLUG16).

OSX is not currently supported, and the build is likely broken
due to differences in dynamic library loading.
