This reverts commit 00a691b9.

This will allow dell's custom syscfg to work correctly.

NOTE: Dell calls flat memory just memory.

Bug 4034

No code change, just moving existing code into a switch ready to handle
multiple options.

Add SystemType to knl_generic.conf for knl_generic in preparations for making KNL work on a Dell system.

Add SystemType to knl_generic.conf.  This is used to distinguish
differences in vendors such as 'Dell'.

Bug 4057.

Starting from glibc-2.25 the macros major and minor are only available
from sys/sysmacros.h. This patch uses an autoconf macro to detect the
location and includes the header accordingly.

Fix mysql plugin to correctly return parent limits for all children.

the tree.

Bug 4050

Would fail when trying to create the clustername file because the
StateSaveLocation path didn't exist yet.

Bug 3988

srun jobs that could start immediately and requested multiple partitions
didn't run in the highest priority partition if the highest priority
partition wasn't listed first.

It's possible that the scontrol show jobs will show the partition list
in priority order now that the job's partition list gets sorted by
priority.

Bug 4015

NULL is returned if the token is not found, testing against '\0'
is wrong (although does work okay in older compilers).

Fixes new GCC 7.1 warning.

Bug 3999

Fix bug in selection of GRES bound to specific CPUs where the GRES count
    is 2 or more. Previous logic could allocate CPUs not available to the job.

bug 4029

Highlight the need to use Slurm abstract CPU ID

When the node isn't actually rebooted, the BootTime isn't updated and
Slurm doesn't consider that the node is returned to service, even
if slurmd is responding.

Bug 4039

This will be fixed before 17.11, but is being left as-is on 17.02.

Bug 3956.

to have 'socket=' in AuthInfo to work.

This is to make it so people don't have to update their slurmdbd.conf's
when upgrading (and to match documentation).

Bug 4009

jobcomp/elasticsearch saves/load the state to/from elasticsearch_state.  Since
the jobcomp API isn't designed with save/load state operations, the plugin
_save_state() isn't extern and not available from outside the plugin itself,
thus it is highly coupled to fini() function. This state doesn't follow the
same execution path as the rest of Slurm states, where in save_all_sate()
they are all independently scheduled. So we save it manually here on a RPC
of type REQUEST_CONTROL.

This enables that when the Primary ctld issues a REQUEST_CONTROL to the Backup
which is currently in controller mode, the Backup will save the state and when
the Primary assumes control again it can process the saved pending jobs.  The
other way around was already controlled, because when the Primary is running
in controller mode and the Backup issues a REQUEST_CONTROL, the Primary is
shutdown and when breaking the ctld main() function while(1) loop, there was
already a g_slurm_jobcomp_fini() call in place.

Bug 3908

Bug 3973.

When more than 1 ping cycle is spawned simultaneously (for instance
REQUEST_PING + REQUEST_NODE_REGISTRATION_STATUS for the selected nodes),
we do not track a separate ping_start time for each cycle. When ping_begin()
is called, the information about the previous ping cycle is lost. Then when
ping_end() is called for the first of the two cycles, we set ping_start=0,
which is incorrectly used to see if the last cycle ran for more than
PING_TIMEOUT seconds (100s), thus incorrectly triggering the:

 error("Node ping apparently hung, many nodes may be DOWN or configured "
       "SlurmdTimeout should be increased");
