xinput_calibrator (generic touchscreen calibrator for xorg)

Fills the gap of touchscreen calibration software, featuring:
* works for any standard Xorg touchscreen driver (uses XInput)
* mis-click detection (prevents bogus calibration)
* dynamically recalibrates the evdev driver
* outputs the calibration as xorg.conf.d snippet
