This reverts commit fd690a9c.

was there for jobs and steps, but for no real reason.  I couldn't see a
reason anyway.

Add missing option for PURGE_JOB which is different than the others
and was missed on the changes made when adding the usage table
flushes.

sstat doesn't work on Cray ALPS but works on native Cray setups.

Bug 3444

There are (or at least used to be) places where an exit code of 0 was used
to indicate that the job ran successfully to completion. This patch fixes
the places where the exit_code was MAX'd out to 1 to indicate that job did
not ran successfully to completion. This MAX logic was introduced in commit
f305f099.

Use instead of the repeated construction of:
bit_not(b); bit_and(a, b); bit_not(b);
to avoid two addition iterations.

Can't set the job_id of a will_run will_run job prior to creating the
job. Invalidates the jobs for non-slurmuser jobs. Also not burning a
jobid could make the will_run job not be distinguishable in the logs.

Will handle the federation aspect of this in 17.11.

Bug 3436

job_write_lock and sleep a second before grabbing it again.  This should probably be made
configurable later on.
