f1d2a9b826 Fix the case where one goes from zero to more than zero items enabled 
in /etc/ttys.  Before this fix, once the count of active services
reaches 0, one could never restart any more without a reboot.

Steve Passe did the leg work on this patch.  After he found the fix,
we discovered that an identical fix had been made to NetBSD.

ba55503fcc I should have committed this ages ago... 
Convert init(8) to use nmount() instead of mount() when
it has to mount devfs.  This doesn't happen normally,
since the kernel is supposed to mount devfs itself.

73c6870b18 Remove 'register' keyword. 
It does not help modern compilers, and some may take some hit from it.
(I also found several functions that listed *every* of its 10 local vars with
 "register" -- just how many free registers do people think machines have?)

9bfb9eedcd Use STD{ERR,IN,OUT}_FILENO instead of their numeric values. The 
definitions are more readable, and it's possible that they're
more portable to pathalogical platforms.

e8e6885c6b Finish up umntall support. init now passed an argument to the 
rundown script 'reboot' or 'single'.  ISO support (which never
    worked) has been removed from mount_nfs.  mount_nfs and umount
    now use mounttab, which allows umntall to work properly.  The
    rc scripts now call umntall as appropriate.

6ed01edd23 FreeBSD kernel doesn't allow any process to decrease securelevel. So, 
init(8) cannot decrease securelevel.  The manual page explains this
and single_user() doesn't try to downgrade kernel to insecure mode.

0e8d0ba0f2 This has always bugged me. At single user, the implied example it gives 
is not valid - it says that "sh" is the default, but you can't
actually type "sh" at this prompt - it has to be /bin/sh or some other
full pathname.

489b7a4fe8 Attempt to open the device for reading before actually adding the device 
to the session list.  If the device comes back as unconfigured, just
ignore that line in /etc/ttys.  If someone HUP's init, we'll try again.

This change stops getty's from hanging on vty and sio ports that don't
exist, either due to LKM drivers not being loaded, or probes failing.
