Return [0-100:2] formatting, rather than [0,2,4,6,8,...] when using
a step function.

Was inadvertantly broken in 14.11 with commit 5ffdca92.

Bug 2535.

Need higher count for KNL processor.

Fix Cray NHC spawning on job requeue. Previous logic would leave nodes
allocated to a requeued job as non-usable on job termination.

Specifically, each job has a "cleaning/cleaned" flag. Once a job
terminates, the cleaning flag is set, then after the job node health
check completes, the value gets set to cleaned. If the job is requeued,
on its second (or subsequent) termination, the select/cray plugin
is called to launch the NHC. The plugin sees the "cleaned" flag
already set, it then logs:
error: select_p_job_fini: Cleaned flag already set for job 1283858, this should never happen
and returns, never launching the NHC. Since the termination of the
job NHC triggers releasing job resources (CPUs, memory, and GRES),
those resources are never released for use by other jobs.

An error in slurmconfgen_smw.py caused it to parse the nic as the nid.
On some systems those values differ, causing the generated slurm.conf file to
be incorrect.

Bug 2532.

route_p_split_hostlist was not thread-safe, and would cause
one of several segfaults depending on where in the initialization
code each thread was.

Bug 2495.

Was incorrectly displaying "(null)" even when loaded successfully.

Added new job dependency type of "aftercorr" which will start a task of a
    job array after the corresponding task of another job array completes.

Bug 2430

We want to introduce a new behavior in the way slurmd uses the
HealthCheckProgram. The idea is to avoid a race condition between the
first HealthCheckProgram run and the node accepting jobs. The slurmd
daemon will initialize and then loop on HealthCheckProgram execution
before registering with slurmctld. It will stay in this loop until
the HealthCheckProgram returns successfully (the node is still DOWN).

On our clusters we are using NHC as an HealthCheckProgram. NHC drains
the node if it fails and remove the drain if it is successfull, this
behavior fits well with our purpose. This behavior permits us to start
slurmd at boot without setting up a complex boot sequence in the init
system, slurmd just wait for the node to be ready before registering.

The HealthCheckProgram is not run during slurmd startup if
HealthCheckInteval is 0.

Bug 2507

Step GRES value changed from type "int" to "int64_t" to support larger
values. Previous logic could fail in step allocation values over 32-bits.
Other GRES values are 64-bit.

slurmstepd to close potential open ones.

It was pointed out the slurmd using acct_gather_energy/ipmi links to
freeipmi which could possibly open /dev/ipmi0 without the close on exec
flag set as root while launching a step leaving it open in the users app.

What this does is sets the flag on the first 256 to mitigate the concern.

Bug 2506

Previous logic tested whatever the job's partition pointer indicated
rather than the partition we are trying to run the job in. This bug
was introduced in Slurm version 15.08.5, Nov 16, 2015, commit
94f0e948
bug 2499

Check that PowerSave mode configured for node_features/knl_cray plugin.
    It is required to reconfigure and reboot nodes. Fatal error if
    not configured.

src/common/mapping.h was the one place outside of slurm/*h that used this,
just remove it from there.

Replace macro with #ifdef __cplusplus in slurm/*h in case anyone is linking
C++ against libslurm.

Macro hasn't been used consistently for three+ years, and is protecting against
compilation by non-ANSI C compilers which has not been a concern for quite some
time. Cleanup formatting of function declarations while here.

No change to logic.

Insure that a job is completely launched before trying to suspend it.
Previous logic would start suspend logic early in the life of the
slurmstepd process, after it's listening socket was open but before
the tasks were launched. This defers the suspend logic until after
all prologs and setup completes and the tasks are launched. This is
important in the case of gang scheduling, in which newly launched
jobs can be immediately suspended.

Default value is 1. Weight is uint32_t so this check was always succeeding.

Add note to slurm.conf man page about setting "--cpu_bind=no" as part
of SallocDefaultCommand if a TaskPlugin is in use.

Revert call to getaddrinfo, restoring gethostbyaddr (introduced in Slurm
    16.05.0pre1) which was failing on some systems. Specifically test7.2
    was failing on some systems with getaddrinfo() returning an error of
    "System error: Resource temporarily unavailable". Partial reversion
    of commit 89621f65

was also given.

Split partition's "Priority" field into "PriorityTier" (used to order
    partitions for scheduling and preemption) plus "PriorityJobFactor" (used by
    priority/multifactor plugin in calculating job priority, which is used to
    order jobs within a partition for scheduling).
