Bug 25537

Since security profiles were introduced in sysinstall, two things
happened.  First, a lot of people started having problems installing
kernels, et cetera because the High and Extreme security profiles
raised securelevel.  Second, a lot of people wanted to know exactly
what those security profiles do.  The first problem has pretty much
been dealt with by appropriate additions to the FAQ.  The second
problem remains.

Fix: I propose we add a help screen to the menu in sysinstall where one can
select a security profile.  Sysinstall already has a mechanism to do
this; the help screen is displayed when a user pushes "F1" (at least
on U.S. keyboards).

The following patch implements the above suggestion.  The feature
table was written by Michael Lea <mlea@atomicbluebear.org> and
submitted via freebsd-security (see "Re: security settings
documentation" on freebsd-security around Feb. 14 2001); consequently,
if this is commited, he should be credited in the commit log.

The patch adds a new file, help/secprofile.hlp (under src/usr.sbin/sysinstall).
