[PATCH] dix: make DeviceEvent coordinates signed for Xinerama. #24986

From: Chris Humbert <freedesktop at mahadri.com>
With Xinerama enabled, event coordinates are relative to Screen 0, so
they can be negative. The new DeviceEvent's coordinates are of type
uint16_t, making screens above and to the left of Screen 0 unusable.
