This is a correction of a bug introduced in commit
https://github.com/SchedMD/slurm/commit/ac44db862c8d1f460e55ad09017d058942ff6499
That commit eliminated the need of reading the node state information
from squeue for performance reasons (mostly for large parallel systems
in which the Prolog ran squeue, which generates a lot of simultaneous
RPCs, slowing down the job launch process). It also assumed 1 CPU per
node. If a pending job specified a node count of 1 and a task count
larger than one, squeue was reporting the node count of the job as
the same as the task count. This patch moves that same calculation
of a pending job's minimum node count into slurmctld, so the squeue
still does not need to read the node information, but can report the
correct node count for pending jobs with minimal overhead.

to avoid it thinking we don't have a cluster name.

in slurmctld.h which is included by slurm_accounting_storage.h which is
included by slurmdbd.c which would cause confusion at the very least.

%o and %Z respectively

Previously there was a sleep(5) during which the backup controller
was non responsive during its startup mode or returning from primary
mode.

This will prevent possible confusion for the backup controller
when it switches from primary back to backup modes since those
pthread IDs are no longer value. Note the thred_id_rpc could be
used by the backup controller after returning to backup mode

they are coordinators over.

Replace fixed size buffer with a buffer that can grow as needed.

and CLUSTER_FLAG_CRAY_N

a Native Cray not making a correct hostlist as well.

If there are completing jobs, a reconfigure will set wrong job/node
state: all nodes of the completing job will be set allocated, and the
job will not be removed even if the completing nodes are released. The
state can only be restored by restarting slurmctld after the completing
nodes released.

and fix warnings.
