slurmstepd to close potential open ones.

It was pointed out the slurmd using acct_gather_energy/ipmi links to
freeipmi which could possibly open /dev/ipmi0 without the close on exec
flag set as root while launching a step leaving it open in the users app.

What this does is sets the flag on the first 256 to mitigate the concern.

Bug 2506

Previous logic tested whatever the job's partition pointer indicated
rather than the partition we are trying to run the job in. This bug
was introduced in Slurm version 15.08.5, Nov 16, 2015, commit
94f0e948
bug 2499

Insure that a job is completely launched before trying to suspend it.
Previous logic would start suspend logic early in the life of the
slurmstepd process, after it's listening socket was open but before
the tasks were launched. This defers the suspend logic until after
all prologs and setup completes and the tasks are launched. This is
important in the case of gang scheduling, in which newly launched
jobs can be immediately suspended.

This also reverts most of commit fa331e30 as well as commit bd9fa830
which would try to set the pn_min_cpus every time a job was updated.
If a job didn't request node counts then they were hosed.

This commit takes away the magic which was screwing things up.  Now the
person gets what they asked for without magic changing things.

This whole process could probably be done better by keeping track of
old values and new values and only calling one function instead of a
pre and post function, but that can probably wait for future generations
of the code as it works now and is probably adequate for the time being.

Control whether the scheduler will continue to try to run jobs in
a partition if a higher priority job is stuck due to an association
limit.

Can cause starvation for larger jobs, but will improve throughput and
utilization for systems that have extensively divvyed up their resources
through association/QOS limits.

have been selected set the time limit appropriately if the job didn't
request one.

If the partition has no DefaultTime setting, and no time_limit was given
for the job, job_ptr->time_limit == NO_VAL.

With AccountingStorageEnforce=safe this will prevent jobs from ever
starting if the association has any limit set for CPUMins.
(NO_VAL * cpus is a very large number, but if no time_limit is given
anywhere that is what they get :))

Support AuthInfo in slurmdbd.conf that is different from the value in
    slurm.conf.
There is a possible bug in the slurm_get_auth_info function (src/common/slurm_protocol_api.c) that can cause the slurmdbd daemon to look for the AuthInfo parameter in slurm.conf instead of slurmdbd.conf when the auth/munge authentication method is used (AuthType=auth/munge).

Here is the slurmdbd log revealing the problem (debug5() printing were added in the sources) :

slurmdbd: slurmdbd version 15.08.7 started

...

Then 60 seconds later, the auth_info value returned by slurm_get_auth_info is NULL:

slurmdbd: debug5: Leaving ../../../src/common/slurm_protocol_api.c, slurm_get_auth_info, auth_info=(null)

and slurmdbd continues without crashing, but I am not sure it is in a safe state.

 }

the auth_info value is now valid and consistent with the slurmdbd.conf setting:
