Peter Hutterer e078a007d6 backends: add support for scroll button locking
Where enabled, the first click of the scroll button sets the button logically
down, the second click sets the button logically up.

This is an accessibility feature, it doesn't require users to keep holding the
button down while scrolling which is hard or impossible for some users.
