At the same time the xinput2 integration is split out of X11Cursor and made a standalone part of the platform plugin. XInput integration is nowadays not only used by the cursor position polling, but also for modifier only shortcuts. By splitting it out the modifier shortcuts start to work also when one doesn't have anything requesting a mouse position polling. This also simplifies the conditional builds: xinput integration is only included if we have support for it at compile time without having to have many ifdefs in the cursor implementation. For the inclusion of cursor in the kcmkwin this also removes all the ifdefs. The key events are only requested if we have xinput 2.1. Otherwise we would not get all raw events if the input device gets grabbed.
