Bug 1348: X11 XI Multitouch: Fixes of previous commit 92006e4baef57f1f3fb647dd307aed5989fd4c8d

Previous commit 92006e4baef57f1f3fb647dd307aed5989fd4c8d

(Note to Danny: I cannot test this now - please re-test and/or review)

X11Common::JavaWindow
- Owns XI extension's xiOpcode, selected xiTouchDeviceId and tracked XITouchPosition array

X11Window::CreateWindow
- Query XI extension only once @ window creation and earmark xiOpcode in JavaWindow instance

- Fix: Device selection code was "class->type != XITouchClass",
  but shouldn't it be 'XITouchClass == class->type' (as patched here)

- Fix: Free XIQueryDevice returned XIDeviceInfo array via XIFreeDeviceInfo

- Earmark deviceid in JavaWindow instance

X11Display
- Moved global static touch_coordinates to JavaWindow::xiTouchCoords instance

X11Display::DispatchMessage
- Changed event handling structure similar to https://keithp.com/blogs/Cursor_tracking/

- Fix: Free XGetEventData's optional memory allocation via XFreeEventData

- Reuse JavaWindow's queried xiOpcode

- Fix: Don't overrise windowPointer, instead validate and require a match. JavaWindow must match!

- Fix: Also validate chosen deviceid with JavaWindow's registered device

Newt Build:
- Added libXi in build recipe and doc
