PluginDir is allowed to be a PATH-style list of directories; remove
incorrect test of the variable as if it were a single directory and
comment that the check for that is elsewhere.

Bug 3361.

Expect is unable to work with more than 32-bit numbers, so it can't
properly test task affinity on KNL with 272 threads

- 2 x Integer handling issues (CONSTANT_EXPRESSION_RESULT)

Warning flag -Wempty-body in clang-3.7 now errors on this, split
macro definition up over multiple lines to silence.

Revision to 06fbdd75
  Previous logic was causing tests 1.87 and 15.19 to fail sometimes
  due to a race condition by adding a "Job allocation revoked"
  message to salloc output even if no allocation occured.
bug 3351

Previous logic was failing if no specialized cores configured on node
  and job wanted to configure some
bug 3349

Null terminate before strchr().

This is a new message when "PrologFlags=contain" or
  "PrologFlags=alloc" is configured.
bug 3351

Cancel interactive job if Prolog failure with "PrologFlags=contain"
    configured.
bug 3351

Minor fix to commit 1e6b7522 in
  the case where user specification of specialized cores is disabled.
bug 3349

If a job specifies --core-spec and the node has identified specialized
  cores using the CpuSpecList option which are not the default cores
  (e.g. the first cores rather than the last cores on each socket),
  the the user's cores will be selected from those identified in the
  configuration.
bug 3349

Was printing int64 using %ld, which generated a warning on some systems

Do not allocate specialized cores to jobs using the --exclusive option.

Fix memory and file descriptor leaks in slurmd daemon's sbcast logic.

The part_ptr is sent into the function, there is no reason to look it up
again.  Coverity reported this.

TravisCI uses 2-cpu nodes, so this causes the test to fail
as a suitable node cannot be found.

Plugins are deprecated and will be removed in 17.02.

version is lower than the min version, set it to the min.

Bug 3050

Address new coverity error report

sched/backfill - Fix logic to reserve resources for jobs that require a
    node reboot (i.e. to change KNL mode) in order to start.

go into JobAdminHeld.

Bug 3201

Fix for possible infinite loop in select/cons_res plugin when trying to
    satisfy a job's ntasks_per_core or socket specification.

Bug 2992.

Modify regression test1.89 to avoid leaving vestigial job. Also reduce
    logging to reduce likelyhood of Expect buffer overflow.
bug 3273

Reverts most of commit 84023f27.

Searching the PATH in slurmd can fail due to root_squash'd NFS
filesystems, leading to the "wrong" program being launched.

If you'd like the performance benefit from avoiding this lookup
during each separate task launch, set SLURM_TEST_EXEC=1 instead
which will perform the lookup once within srun, which then ensures
the lookup happens under the users own environment and not that
of the slurmd.

Bug 2992.

If running burst_buffer/cray plugin on emulated Cray (NOT a real
   Cray system with Cray APIs) and the burst buffer state information
   includes information about buffers associated with jobs which
   are either completed or no longer exist (i.e. the burst buffer
   state information is old), then ignore that old state information.
   This might possibly be related to bug 3295 if their configuration
   is bad.
