Change the way moused talk to syscons, now its only delivering mouseevents

Browse source 
via an ioctl (MOUSE_ACTION).
Fixed a couple of bugs (destructive cursor, uncut, jitter).
Now applications can use the mouse via the MOUSE_MODE ioctl, its
possible to have a signal sent on mouseevents, makeing an event loop
in the application take over mouseevents.
