in the case of ugen devices.
suggestions and ok todd@

same rules to both wskbd0:wskbd and wsmouse0:wsmouse; miod ok

- 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@

ok, deraadt@

ok miod@

Tested by various people on various platforms, I'm willing to fix any
breakage this causes.
ok niels@ deraadt@ and mickey@ (after his comments were applied)

make -> ${MAKE}
add phony targets
remove unnecessary subshells
install kernel in a separate target from building.
some SUDO.
okay deraadt@

anyways)

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