libinput: Upgrade 0.7.0 -> 0.18.0
Upgrade is also required for wayland/weston 1.8.x
libinput license changes are
- COPYING: note that having linux/input.h in the tree does not make libinput GPL
- Updated to 2015 where appropriate, added where missing.
- filter: add Simon's copyright
This code was largely lifted from the X server in
bb25b2ad297891430606c367bfabc but didn't take the copyright messages
that applied to that code.
- Change MIT X11 to MIT Expat license
