This has been the default for slurm.conf since 2008, make it the
default for slurmdbd.conf now.

It turns out it is fairly easy with het jobs to hit this and seg fault srun.

doesn't exist yet (seg fault), and will get blown away in a few lines
when _build_bitmaps() is called.  That function should set things up
correctly anyway.

to run the regression tests 24.* without changing that code since it links
directly to the priority plugin where that function isn't defined.

Bug 5558

Continuation of commit 21d2ab6e

With the change to use tres_usage_type's the stats coming back from the
extern step are initialized to INFINITE64 instead of 0's.

jobacctinfo_create() in _handle_stat_jobacct() initializes jobacct, but
since the job->task[i]->pid == -1, no stats are gathered and the clean
jobacct is returned.

Bug 5554

Most calling paths to job_signal() were sending in job_ptr->job_id alongside
uid 0. This bypasses the unneeded uid validation, and forces another lookup
through find_job_record() for a job_ptr we just dereferenced.

So - change the less-used job_signal() to job_signal_id(), promote
_job_signal to an extern taking that name over, and stop this whole
unnecessary extra set of lookup calls.
