the mux devices.

inside amd source code.  I could not figure out.  So here it goes,
until some rocket scientist points out how to do it in the real source.

draft-ietf-ipngwg-rfc2553bis-03.txt.  backward compatibility concern:
- should be safe to change signed to unsigned, as we never return
negative value.
- sizeof(int) is 4 for all archs, so there's no size change with socklen_t
(= u_int32_t)

Remove creation of non-wsmouse device in MAKEDEV (/dev/lms{0,1}, /dev/mms{0,1}
/dev/psm0, /dev/pms0).
Remove cdevsw[] entries for the devices above, as new mouse protocols are only
accessible trough /dev/wsmouse. aaron@ ok.

6 are enabled by default. After these changes, to enable more you must
change the "option WSDISPLAY_DEFAULTSCREENS" in the kernel config file and
edit /etc/ttys to switch the new ones from 'off' to 'on'.

default security checking.

makes the PGUP and PGDN keys work again as expected.

fixes pr#1660 from wilfried@telia.com .. Thanks!

become default in a few moments once deraadt commits new kernel config files.
IMPORTANT NOTE: A few important pieces are still required to be worked out
over the next few days. Users (and developers) relying on X should probably
stay away from -current until further notice. This should not take long, but
here is your first heads up. If you decide to upgrade your kernel anyway,
be sure to update your /etc/ttys file to use vt100 instead of vt220. The
rest of the fallout from this should be minor.

(rtadvd will derive the configuration from kernel settings).
make it clearer that rtadvd.conf is not necessary, in manpage.
sync with kame.
