Optional XI2.1 support

This patchs adds optional XI2.1 support to utouch-frame. The
utouch/frame-xi2.h header contains helper functions equivalent
to utouch/frame-mtdev.h. In addition, the device-to-screen mapping
is handled via XEvents and optionally XIPropertyEvent. The latter
allows free device placement via xinput set-prop, useful in multi-
head setups, thanks to Chase Douglas. Touch frame events can be tested
using the utouch-frame-test-xi2 tool. Use --with-xi to enable.
