Fix security issue caused by insecure file path handling triggered by
the failure of a Prolog script. To exploit this a user needs to
anticipate or cause the Prolog to fail for their job.

(This commit is slightly different from the fix to the 15.08 branch.)

CVE-2016-10030.

Fix security issue caused by insecure file path handling triggered by
the failure of a Prolog script. To exploit this a user needs to
anticipate or cause the Prolog to fail for their job.

CVE-2016-10030.

This modifies the logic in commit e089b63a for better clarity

Prevent "stray" jobs from using resources when the srun/salloc
will never launch the actual compute tasks.

Bug 3344.

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.

  when the man page was removed

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.
bug 3346

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 3329

Bug 2992.

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