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.
