Previously it was taking the MIN, without respecting the order.

Also add a note to the resource_limits.html page to clarify the
exception for Max[Wall|Time] and/or [Max|Min]Nodes limits, where
the default is that the Partition is the king with regards of
precedence, unless the respective job's QOS flags
Partition[Min|Max|Time]Limit are set.

This prevents a hard-to-diagnose issue where slurmstepd may fail
to start due to a missing library. This now ensures slurmd will
fail, and keep the node down until the library issue can be fixed.

Bug 4645, 4644.

fatal() calls exit(1) which precludes getting a backtrace.
That's fine on configuration issues and other types of problem,
but for hitting "impossible" edge cases getting a core dump may
be the only way to isolate the issue.

Adding to 17.11 so we can easily provide diagnostic patches without
needing users to back-port this implementation. Further use will
come in 18.08.

Add switch/cray to the list, and remove a reference to (long-defunct)
Myrinet.

MUNGE should always be upper case.

MUNGE is the only supported authentication.

Remove confusing (and incorrect, depending on your interpretation)
note about "Slurm jobs can be preserved".

keyvalue_initialized is reset on 'scontrol reconfigure' and other
cases, which can lead to additional atfork handlers being registered.

These can eventually lead to a segfault if an excessive number of
handlers have been re-registered. Set a separate boolean to protect
against this. Clear that boolean as part of the atfork handler.

Bug 4723.

UsePss was correct, but UsePSS and usepss would be silently ignored,
leading to confusion as to whether the option was working or not.

Treat all JobAcctGatherParams as case-insensitive to avoid confusion.
