Add separate event input type for terminal+vo

Add an input/input.c fd type whose read function takes no arguments and
returns no value. If such a function reads key or command events it'll
add them to the queues itself. Use this type for terminal input which
was special-cased before. The event function for X11-based VOs will use
the same type later.
