Hello

The following patch creates a new minor device inside wsdisplay space
(c, 47,254) that can be used to retrive events that happen from inside
wsdisplay. I've named it /dev/wsdisplay but this can be changed if
you want... This patch implements this device using the same technique
as wsmouse or wskbd. It uses an wsevent queue where kernel injects
events and the user can read them.

I've also added a ioctl routine for the device to group some more
ioctl's inside this device (i.e. get active console number by hand,
instead of when it happens).

This patch will help the console mouse driver to know when wsdisplay
events happen (user changes screen, enters X... this last one has to
be implemented) and act consequently to avoid console corruption.

I would like you to review the code and tell me if you feel I've done
it bad or if it is "ok". I've also attached a weird test.c program
that shows how the thing works for the moment.

If you think this is ok, I'll continue with the mouse support using
this new device and I hope I'll have the whole thing finished soon.

Thank you.
