Bug 4621

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.

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.

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.

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.

 -- 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.

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.

Bug 4127

When --mail-type option isn't requested with ARRAY_TASKS, we need somehow
to summarize the different states each task finished in the array. We've
added a new ARRAY_TASK_REQUEUED flag to the array_flags to indicate that
at least one task was requeued. Also the logic now detects if at least
one task failed and/or if otherwise all finished successfully.

The patch also removes the RunTime from the the e-mail when summarizing
whole array, since it doesn't make sense to specify just the RunTime
of one of the tasks for this case.

Patch also fixes when ARRAY_TASKS is specified, previously the mail
notification for the master job task record included a range of
ExitCodes for all the tasks. Since this option is not for summarizing,
the patch makes it so only the range is shown when the option isn't
specified.
