Bug 4584

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.
