Peter Hutterer dce40e2266 Xi: always return BadMatch for XTest devices ChangeDeviceControl requests ...

The only controls that still do something are DEVICE_RESOLUTION and
DEVICE_ENABLE.

XTest devices have no resolution to change, and they cannot be disabled. So
skip the lot, and prevent a crash in the DDX when it's trying to
de-reference pInfo->control_proc on device with no pInfo struct.

Likewise, don't allow setting device mode or the valuators.
XTest pointers are always relative, they don't have a mode.

Test cases:
xts5/XI/ChangeDeviceControl (1/10)
xts5/XI/SetDeviceValuators (1/6)
and a few others
