[DragonFlyBSD - Submit #2921] Allow moused to accept userland mouse events

[sigttou]

Issue #2921 has been updated by sigttou.


I tested the attached patch with FIFO input. XY movement still works, and wheel events now arrive correctly, including negative movement and split packets. Level 0, level 1 and the default level work in these tests. Could it be applied?

Allow moused to work with sysmouse when the port is a pipe,
 not a real mouse device with working ioctls. Allows simple userland injection
 of mouse events.

Attached is an example that works with the Griffin PowerMate
https://www.amazon.com/Griffin-Technology-NA16029-Multimedia-Controller/dp/B003VWU2WA/

Just run `./scrollwheel.py scroller.fifo` as a user account, and then run `moused -p scroller.fifo -t sysmouse` as root. 

If you press down the wheel, it will multiply scrolls by 32, so you can fly through code like in the movies.
