- refer to the section 4 manual page for every device target, whenever
possible
- repair a few minor quoting errors
- repair a few sorting errors
- fix a few device descriptions (ideally they would be synched with the
.Nd line of their manpages, but we are not there... yet)
- minor mdoc fixes
Thanks to jmc@ for review and a lot of constructive criticism.

- homogenize section order
- sort devices inside sections
- make sure all platforms provide a local target (sigh)
- remove a few dead devices not worth mentioning on a few arches while there.

ioctl(2), an unprivileged process may allocate a pty and have its owner
and mode set appropriately.  This means that programs such as xterm and
screen no longer need to be setuid.  Programs using the openpty()
function require zero changes and will "just work".
Designed by beck@ and deraadt@; changes by beck@ with cleanup (and
a rewrite of the vnode bits) by art@ and tweaks/bugfixes by me.
Tested by many.

pointed out by todd@

Tested by various people on various platforms, I'm willing to fix any
breakage this causes.

As a bonus, we do not need awk(1) anymore to run MAKEDEV.

provide '[ "$DEBUG" ] && set -x' inside R() for debugging help ..

fix my previously bogus MAKEDEVs.
If you used pf on a non-i386. the major device number has changed,
and you'll need to recreate /dev/pf

licence in a way that makes ipf not free according to the rules we
established over 5 years ago, at www.openbsd.org/goals.html (and those
same basic rules govern the other *BSD projects too).  Specifically,
Darren says that modified versions are not permitted.  But software
which OpenBSD uses and redistributes must be free to all (be they
people or companies), for any purpose they wish to use it, including
modification, use, peeing on, or even integration into baby mulching
machines or atomic bombs to be dropped on Australia.  Furthermore, we
know of a number of companies using ipf with modification like us, who
are now in the same situation, and we hope that some of them will work
with us to fill this gap that now exists in OpenBSD (temporarily, we
hope).

in some MAKEDEVs, will see to them in a separate commit.

/var/spool/lock becomes uucp.dialer, mode 1775, and serial devices
become uucp.dialer, mode 660.
(A couple of "dead" MAKEDEVs have been updated because they conformed the
the old permission scheme, while others have not because they didn't.)

during installs where there is no MAKEDEV.local.

Removed MI *dev_decl() stuff that is now in sys/conf.h
