Adding mice and bitpads

Sharing a mouse with several terminals

When a mouse is shared among several terminals, the mouse is associated with the first user to invoke a mouse-enabled program for the duration of that program. For another user to use the mouse, the first user must quit the program to close the input queue from the mouse.

NOTE: Note that other users on ttys allowed to use a mouse can use programs that accept mouse input while the mouse is busy. The programs are unable to receive input from the mouse but should otherwise function normally.
