Bug 4655

Turns out there are many ways to get this information directly from
the slurmstepd.  As you can already get this information from ps we
decided to just revert back to the old non-authenticated way of doing
things.

If we do need this in the future we need to patch the stepd as well as
the slurmd here in all the RPC's that try to grab this.

A user could easily run scontrol (or their own home baked thing)
on the node which will give them a direct contact with the slurmstepd.

This isn't a real problem, but older compilers will complain about it.
Newer compilers know in order to get into the place it could be used
'have_count' would have to be set.  If that is set then feature_list
would also be set.

Bug 4638

Test 3.11, file inc3.11.9 only runs for some configurations, but
  assumes no leading zeros in node name suffix. When run with
  nodes named "nid[00001-00005]", the test converted the last
  number to it's numeric for and as making requests for
  "nid[00001-5]", which would fail.

Fix output file containing "%t" (task ID) for heterogeneous job step to
    be based upon global task ID rather than task ID for that component
    of the heterogeneous job step.

This expands some comments
Explicitly sets some pointers to NULL after memcpy (these are
   redundant, but add clarity) and
Move a memcpy to avoid modifying the wrong values

Fix for possible memory corruption in srun when running heterogeneous
job steps.

Turns out you can't use a list_for_each and lock something inside the
list_for_each function that does a lock without the write lock.

Otherwise undocumented, and does not do anything.
Will be removed in 18.08.

Fix job array dependency with "aftercorr" option and some task arrays in
    the first job fail. This fix lets all task array elements that can run
    proceed rather than stopping all subsequent task array elements.
Bug 4590

Creating a copy of the actual environment in env->env defines a new pointer,
then next call to setup_env and setenvf doesn't define variables in the global
environment but in this new copy.

Bug 4615

This fixes the problem introduced in by commit
777a45f9 and maintains proper PMIx
operation.
bugs 4132 and 4615

node_feature/knl_cray - Fix memory leak that can occur during normal
    operation. This will happen when an update request for a specific
    node happens.

If CnselectPath and/or SyscfgPath defined in knl_cray.conf file and
  slurmctld reconfigured, the original values of those paraemters
  would be over-written and their memory leaked.

Use FREE_NULL_BUFFER instead, otherwise we could attempt to
free_buffer a second time if we jump to the rwfail label.
