the execve() call to launch an application can fail due to the
  system limit on open files or memory being reached. This adds
  retry logic.
bug 1803

Also add some cosmetic changes

bind to the interface of return of gethostname instead of any address on
the node which avoid RSIP issues in Cray systems.  This is most likely
useful in other systems as well.

Add level to switch table information logged by select plugin

Old logic could purge a job record for a job that was in
  completing state (if there was also a lot of agent threads).
  This change prevents purging job records for completing jobs.

Fix to job array update logic that can result in a task ID of 4294967294.
To reproduce:
$ sbatch --exclusive -a 1,3,5 tmp
Submitted batch job 11825
$ scontrol update jobid=11825_[3,4,5] timelimit=3
$ squeue
             JOBID PARTITION     NAME     USER ST       TIME  NODES NODELIST(REASON)
           11825_3     debug      tmp    jette PD       0:00      1 (None)
           11825_4     debug      tmp    jette PD       0:00      1 (None)
           11825_5     debug      tmp    jette PD       0:00      1 (None)
             11825     debug      tmp    jette PD       0:00      1 (Resources)
A new job array entry was created for task ID 4 and the "master" job
array record now has a task ID of 4294967294.
The logic with the bug was using the wrong variable in a test.

Bug 1799

Increase total backfill scheduler run time in stats_info_response_msg data
    structure from 32 to 64 bits in order to prevent overflow.

Replace logic of this form:
   if (x) {
     list_destroy(x);
     x = NULL;
  }
with the simpler
FREE_NULL_LIST(x)

performance improvements in the slurmctld agent code, see commit
53534f49

Modify slurmctld outgoing RPC logic to support more parallel tasks (up to
    85 RPCs and 256 pthreads; the old logic supported up to 21 RPCs and 256
    threads). This change can dramatically improve performance for RPCs
    operating on small node counts.

Change the case of "FAILURE" to "failure" in a test so we don't see
  upper case "FAILURE" on expected behaviour.

little adding the extra hops, but if you are running a bunch of different
small steps it can help out a lot on messages going to the controller.

Correct "sdiag" backfill cycle time calculation if it yields locks. A
    microsecond value was being treated as a second value resulting in an
    overflow in the calcuation.

message that may come.

The slurmctld logic throttles some RPCs so that only one of them
can execute at a time in order to reduce contention for the job,
partition and node locks (only one of the effected RPCs can execute
at any time anyway and this lets other RPC types run). While an
RPC is stuck in the throttle function, do not count that thread
against the slurmctld thread limit.

Some dead assignments, memory leaks, unitialized variables, etc.

Changed spaces to tabs at start of lines.
Minor changes to some formatting.
Added the new files to the RPM (slurm.spec file).
Prevent memory leak of "l_name" variable if which_power_layout()
    function is called more than once.
Initialize "cpufreq" variable in powercap_get_cpufreq() function.
Array "tmp_max_watts_dvfs" could be NULL and used if "max_watts_dvfs" variable is
    NULL in powercap_get_node_bitmap_maxwatts_dvfs()
Variable "tmp_pcap_cpu_freq" could be used with uninitialized value in function

Variable "tmp_max_watts" could be used with uninitialized value in function

Array "tmp_max_watts_dvfs" could be used with uninitialized value in function

Overwriting a memory buffer header (especially with different data types) is
    just asking for something bad to happen. This code from function
    powercap_get_job_nodes_numfreq():

[PATCH 4/5] correct bugs in powercapping logic and fix function for
 optimal frequency

[PATCH 3/5] Adapt the power_cpufreq layout and set the
 CurrentCoreWatts value based on the selection of the
 resources and the choice of CPU Frequency.
 CurrentCoreWatts are set to IdleWatts when one or more
 jobs occupy other resources of the node and set to 0
 when the node is free. The above algorithm is activated
 only when powercapping is active.

[PATCH 2/5] Add powercapping logic to make use of the power_cpufreq
 layout. The new logic allows the usage of only one of
 the existing layouts either power or power_cpufreq to
 take into account for the power adaptive scheduling. It
 considers the cpu frequency possibilities of the nodes
 as populated within the layouts along with the jobs'
 choices for allowed cpu frequencies for their
 execution. Based on the available power budget and the
 cluster's current maximum consumption it calculates if
 the job can be allocated and if yes with which allowed
 CPU frequency.

[PATCH 1/5] powercapping: add new power_cpufreq layout to use as an
 alternative to the power layout for power adaptive scheduling
