Modify DataWarb example to use an environment variable rather than absolute path

new glibc 2.24+ that depricates readdir_r.

This reverts commit 8bc8e7e6.

The slurm_strcasestr() which existed in v16.05 was removed in v17.02.

Fix for possibly treating a negative number as a positive.

Change the default syscfg path to /usr/bin/syscfg
Don't load the plugin if ResumeProgram is configured
Update documentation on web page

This applies only to knl_generic plugin. The original node active
features should be the same as the features field at startup.
The logic was assuming the original value was NULL.

This was a new function added to support knl_generic and it was
  originally assigned the wrong name.

Added node_features/knl_generic plugin for KNL support on non-Cray systems.
NOTE: This plugin is still under development.

Do not propagate SLURM_UMASK environment variable to batch script.
bug 2609

Correct a bitmap test function (used only by the select/bluegene plugin).
  The effect of this bug is probably very limited as it will in almost
  all cases revert prematurely to a bit-by-bit test rather than using
  a full-word test.
bug 3145

Cannot use ClusterName without reading a config file
that may not exist.

Bug 3026.

This introduced an inadvertent dependency on the config file,
which does not exist when setting up a new cluster.

Bug 3026.

This reverts commit c39f9ac9.

task/affinity plugin: Honor a job's --ntasks-per-socket and
    --ntasks-per-core options in task binding.
bug 3118

Changed in df70b651

Preserve non-KNL node features when updating the KNL node features for a
    multi-node job in which the non-KNL node features vary by node.

node_features/knl_cray plugin: If the reconfiguration of nodes for an
    interactive job fails, kill the job (it can't be requeued like a batch job).

Execute "capmc node_status" at more frequent intervals to handle
  nodes getting added or removed from the system using Cray tools
  (i.e. try to keep Slurm and Cray software better synchronized).

node_features/knl_cray plugin: Add separate thread to interact with capmc
    in response to unexpected node reboots.

bug 3155

Prevent possible divide by zero in select/cons_res if a node's board count
    is higher than it's socket count.
bug 3155

If a node's socket or core count are changed at registration time (e.g. a
    KNL node's NUMA mode is changed), change it's board count to match.
bug 3155

Cray: The slurmd can manipulate the socket/core/thread values reported based
    upon the configuration. The logic failed to consider select/cray with
    SelectTypeParameters=other_cons_res as equivalent to select/cons_res.
bug 3155

abs() should not be used on long long variables as it would
truncate if strictly confirming to C99. Use llabs() instead.

Fix to commit 2aefc66b.

These tests fail with a configuration of CR_ONE_TASK_PER_CORE.
  The tests are being disabled now for such a configuration, but
  could be modified to run in such an environment in the future.

Correct SchedulerParameters=bf_busy_nodes logic with respect to the job's
    minimum node count. Previous logic would not decremement counter in
    two locations and reject valid job request for not reaching minimum
    node count.
