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.

This reverts commit ff3e77f4.

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

This should never happen with a valid feature specificiaton

in the current directory but not in the --chdir specified cwd.

Now srun looks for the command in specified cwd and differentiates all
the possible cases where a command starts with ./ (relative), with /
(absolute), and with a different char indicating a command that is in
the path.

Fix also for a PATH variable starting by '.', now it is relative to
specified cwd.

bug 4392

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.

 -- node_features plugin - Add suport for XOR & XAND of job constraints (node
    feature specifications).
 -- Add support for parenthesis in a job's constraint specification to group
    like options together. For example
    --constraint="[(knl&snc4&flat)*4&haswell*1]" might be used to specify that
    four nodes with the features "knl", "snc4" and "flat" plus one node with
    the feature "haswell" are required.

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.
