Running slurmctld under valgrind while operating with jobcomp/elasticsearch
reported the following bytes definitely lost:

It turns out the generated buffer in slurm_jobcomp_log_record was xstrdup'ed to
the corresponding job_node->serialized_job, but the originally generated buffer
wasn't freed afterwards. The fix consists in change the transfer so that instead
of xstrdup'ing the char * we just assign the pointer and NULL the buffer.

The job_node->serialized_job was already xfree'd properly later when the job
was indexed.

Bug 4065.

Otherwise a race between threads in _check_node_status leads
to a crash.

Bug 4094

Given a configuration with TopologyParam including Dragonfly option, if a
job requested --switches count, the count timeout specified by either
the job request or max_switch_wait SchedulerParameters was not respected.
This was due to leaf_switch_count variable not being incremented in
_eval_nodes_dfly() function when needed, as we do in _eval_nodes_topo(),
the later being a execution path which already succeed to wait for the
switch count timeout.

This reverts commit 00a691b9.

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

NOTE: Dell calls flat memory just memory.

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 4034

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.

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).

Continuation of last commit

Bug 4009

Fix regression in commit e5c05549 that would put the stepd pid into the memory cgroup instead of the task's pid.

Beforehand this would put the result of getpid() into the cgroup.  Before
e5c05549 this was done in the child of the fork which would get you
the task's pid, but moving it to run in the parent broke this logic.

What this patch does is adds pid to the input parameters of
task_g_pre_launch_priv making it so we could use the correct pid.

Fix for possible slurmctld abort with use of salloc/sbatch/srun
    --gres-flags=enforce-binding option.

Otherwise we can end up printing Start times greater than End times,

burst_buffer logic modified to support sizes in both SI and EIC size units
    (e.g. M/MiB for powers of 1024, MB for powers of 1000).
bug 3922

Changes the alpsc_configure_nic() call to set the exclusive flag,
and 100 for both the cpu and memory scaling values.

Should only be used with exclusive jobs without concurrent steps
running on a node, otherwise oversubscription of the GNI resources
can occur leading to performance issues.
