Correct error message when ClusterName in configuration files does not match

This would make --hint=multithread not work at all.

Turns out if the extern step is created here and the job was killed long
before hand the step is made erroneously and can cause an assert just lines
later.

What this does is populate the node_hash_table as nodes are being read in
instead of after the node_record_table_ptr has been fully populated.

This speeds up a start of a slurmd with a system of 10000 nodes from
> 1 minute to less than a second.

In 17.11 we will remove the linear xstrcmp check as it should no longer be
needed.

Improve selection of jobs to preempt when there are multiple partitions

Prevent segfault from pointer dereference to the QOS that is
being deleted.

Fix to commit 3e8aa451.

Fix regression from commit c05dcb8a (bug 1923) that doesn't take
into consideration a blank char * as a valid option.

This fixes the scenario like

sacctmgr list associations user=''

which would only print account associations.
Bug 3862

a good return code.

This also fixes the situation where the step was ending but not yet ended
so it sends the KILL_TASK_FAILED error instead of JOB_NOTRUNNING.

Also it removes the abort in favor of exit which it should had been anyways.

Inadvertently set to one when requested.

Bug 3855.

Bug 3857.

File deletion can be slow, especially when StateSaveLocation in on
NFS or other network filesystems. Since purge_old_job() holds all
the slurmctld write locks, this is especially performance sensitive.

Moving this to an independent thread lets the slower filesystem
cleanup happen without owning these locks. purge_old_job() then
results in the purged job ids being queued in the purge_list.

A race with the job id potentially wrapping around again is already
prevented by _dup_job_file_test() in get_next_job_id().

Two jobs completing simultaneously leads to make_node_idle()
returning before it has a chance to decrement node_ptr->owner_job_cnt,
which can result in the node being "owned" by that user even
through no jobs are running on it.

Move the decrement block to the end at a fini label, and make sure
all return paths pass through it. While moving that add a guard
against node_ptr->owner_job_cnt underflowing.

Bug 3771.

If a job is considered on a partition with ExclusiveUser=YES
then it would be marked as if it was submitted with the
--exclusive flag, which would lead to delays launching it
on ExclusiveUser=NO partitions, and cause lower-than-expected
cluster usage.

As a side effect, the job_ptr->part_ptr->flags need to be
tested wherever WHOLE_NODE_USER is considered, instead of
just job_ptr->details->whole_node.

Bug 3771.

_setup_assoc_cond_limits was using the table 'prefix' passed by argument
in the where clause to select the where clause prefix.deleted=something.

It turns out that _setup_assoc_cond_limits is called by these functions:
as_mysql_modify_assocs
as_mysql_remove_assocs
as_mysql_get_assocs
as_mysql_acct_no_users

which set the prefix to 't2' before the call if a QOS is provided or if
WithSubAccounts is provided. The 't2' prefix is fine for other where
conditions in that case, but for choosing the deleted we need the t1
which is the table we're selecting the records off.

Bug 3821

'scontrol update reservationname=foo duration=unlimited' sets INFINITE
as the duration, which needs to be translated to a year as is done
elsewhere. Otherwise it'll convert to 49710 days, which is definitely
wrong.

MAX() will re-evaluate the higher value argument; if this is a function
is may be called twice over, leading to unintended side effects or a
crash.
