Committing now so that it gets broader testing.
Man page bits will be added once we are confident there is no side
effect and this can stay.

- use [[ $1 == autoboot ]] to avoid a shell error message due to
possible spaces in first argument

Nobody should use DES crypt anyway these days.

The only place local_rcconf could have been defined is from /etc/rc
sourcing rc.conf but then the variable is not exported so it will never
be seen by rc.subr.

unmapping of freed allocations without disabling chunk randomisation
like the "Freeguard" ('F') option does. Make security 'S' option
use 'U' and not 'F'.
Rationale: guarding with no chunk randomisation is great for debugging
use-after-free, but chunk randomisation offers better defence against
"heap feng shui" style attacks that depend on carefully constructing a
particular heap layout so we should leave this enabled when requesting
security options.

this file, even years after the rc.conf / rc.conf.local split happened.
One way to improve upon this is to put a big fat comment at the top of
the file.  (Other ways to improve this is by renaming files, but that
will just create more confusion).
