Subject: [PATCH] event: Add symbolic names for left, middle, and right buttons

Symbolic names are better than magic numbers, even if they are
well-established and won't likely change.

This maps to a commit in GTK+ that introduced the same names; it
was decided to go for PRIMARY, MIDDLE, and SECONDARY because of
the confusion that may arise when the button order gets flipped
in left-handed configurations - the "left" button (i.e. 1) becomes
the right-most button, and the "right" button (i.e. 3) becomes
the left-most button.
