Improve backfill scheduling algorithm with respect to starting jobs as soon
    as possible while avoiding advanced reservations.

Bug 3581.

The SLURM_ID_HASH used for Cray systems has changed to fully use the
entire 64 bits of the hash.  Previously the stepid was multiplied by
10,000,000,000 to make it easy to read both the jobid as well as the
stepid in the hash separated by at least a couple of zeros, but this
lead to overflow on the hash with steps like the batch and extern step
where they used all 32 bits to represent the step.  While the new method
ruins the easy readability it fixes the more important overflow issue.
This most likely will go unnoticed by most, just a note of the change.

It would be nice to figure out a way to remove the check for version all
together but I (Danny) couldn't figure out how that would be done since we
need to know which libs/headers to use and on systems with multiple
installed and no 'lua' lib (Ubuntu) you have to use the PKG_CHECK_EXISTS
to set up the pkg name for PKG_CHECK_MODULES or you don't get things set up
correct when trying to link.

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.

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.

which the backfill test window expands. This can be used on a system with
a modest number of running jobs (hundreds of jobs) to help prevent expected
start times of pending jobs to get pushed forward in time. On systems with
large numbers of running jobs, performance of the backfill scheduler will
suffer and fewer jobs will be evaluated.
