xcb: Use XCB instead of Xlib for XInput
- Replace xinput2 feature by xcb-xinput, which doesn't depend on xcb-xlib - Remove xi2PrepareXIGenericDeviceEvent() that was used to fix incompatibilty between XCB and libXi structs - Drop XCB_USE_XINPUT21 and XCB_USE_XINPUT22 defines that were needed with libXi Although xcb-xinput was released in version 1.13 of libxcb, it was quite stable in version 1.12, and the parts that we use did not change between versions, so require system xcb-xinput 1.12. [ChangeLog][X11] The xcb plugin was ported to use libxcb-xinput instead of libXi for XInput2 support. The -xinput2 configure option was replaced by -xcb-xinput.

The '-qt-xcb' configure option can be used to get rid of most xcb- dependencies. Only libxcb will
still be linked dynamically, since it will be most likely be pulled in via other dependencies anyway.
This should allow for binaries that are portable across most modern Linux distributions.
-PACKAGE VERSION REQUIREMENTS
-When using touch input via XInput 2.2 or higher, there is a potential issue on systems that ship with
-a libXi older than 1.7.5. This is because XIAllowTouchEvents can deadlock with libXi 1.7.4 and earlier.
-When touch events are never received, this is not an issue, so plain mouse/keyboard systems are not affected.
-Qt versions before 5.8 attempted to recognize this scenario based on the pkg-config package version and skip
-the call. This has been removed starting from 5.8 since relying on pkg-config package versions is unsafe given
-that Qt must also support systems with limited or incomplete pkg-config setups.
