While restarting slurmctld with -R flag, features were emptied.
This patch just does nothing when recover=2 (-R) which means active and
available features are preserved from the state files. Needed for
backup slurmctld controller.

Bug 4882

If block_map_size is zero (as seen on FreeBSD when not using HWLOC),
xmalloc(0) will return NULL. Writing to str[0] then is invalid.

Bug 4845.

Bug 4971

-X doesn't show cumulative statistics for each job but statistics relevant to
the job allocation itself.

Bug 4967

It fixes a scontrol segfault when updating a reservation with empty users or
accounts and the parameters were specified more than once.

Bug 4949

Initialize cluster_name to NULL, allowing it to be safely
g_free'd later on.

Bug 4898.

Bug 3318

Use unpackstr_xmalloc_chooser as part of safe_unpackstr_xmalloc macro.
This ensures that the slurmdbd is always working on escaped strings.

Fixes CVE-2018-7033.

Bug 4792.

Reset the original time_limit value afterwards, otherwise the job
time may get squashed down to as low as 1 minute.

This should expose O_CLOEXEC on older glibc versions,
addressing build issues on CLE 5.2.

Bug 4843.

MsgType=6500 wasn't being expanded:

"
slurm_persist_conn_open: Something happened with the
receiving/processing of the persistent connection init message to
XXX.XXX.XXX.XXX:6819: Failed to unpack MsgType=6500 message

(slurmdbd was down when slurmctld was started).

Bug 4888

Set scontrol exit code to 1 if attempting to update a node to
DRAIN or DOWN without specifying a reason.

when slurmctld was started) you could loose QOS usage information.

Looks like a regression accidentally introduced in d8770a66.

Bug 4769.

Bug 4549

Could happen if SuspendTimeout was shorter than ResumeTimeout.

Bug 4863

Continuation of 7d246784

Also throws spurious errors of:
"slurmd: error: Domain socket directory /var/spool/slurmd: No such file or directory"
if you SlurmdSpoolDir is located elsewhere.

Bug 4289.

Add additional protection in slurmctld as well.

Bug 4826.

job_limits_check() uses the job desc to call _valid_pn_min_mem(). This
second function might adjust the following values (up to date):

cpus_per_task
pn_min_memory
min_cpus
max_cpus
pn_min_cpus

If the function returns success, these adjusted members need to be copied
back to the job_record. It turns out pn_min_cpus wasn't copied back,
thus the logs claimed to automatically increase pn_min_cpus but actually
the job record wasn't modified and the select plugin tried to allocate
wrong amount of resources.

Bug 4823.

No longer needed, and will cause errors on FreeBSD systems
build with WITHOUT_KERBEROS.

Bug 4805.

Bug 4783

"#DW destroy_persistent" directives available in Cray CLE6.0UP06. This
will be supported in Slurm version 18.08. Use "#BB" directives until then.

Bug 4302

Only a single io_timeout_thread should be created for each sls struct.

Creating multiple, while seemingly harmless in operation, can lead to
fatal() messages when srun shuts down by destroying mutex locks that
are in use by threads that srun doesn't expect to still have running.

Regression caused by a1185f04.

Bug 4596

This patch fixes the situation that makes features unrecognized where a node
features plugin is active and features are defined to nodes in slurm.conf.

It also preserves KNL node features when slurmctld daemons are reconfigured
including active and available modes.

Features not belonging to node features plugin are reset to what is in
slurm.conf when restarting or reconfiguring.

Bug 4734

_resv_overlap function was only checking the flags for the updated
reservation, but not for the rest of present ones. This implied
that the allowed overlap derived from these flags only applied
depending on the update order.
