Instead of returning BadAccess when "read" permission is denied
on a device, falsify the device state (buttons down, keys pressed).
This is nicer to applications, but may still have undesired side
effects. The long-term solution is not to use these requests in
event-driven code!
Requests affected: QueryPointer, QueryKeymap, XiQueryDevice.

If the check fails, leave the device off the returned list of info
structures. Under XI2, this may cause inconsistent views of the device
topology after a change (for example, devices disappearing from view,
or showing as attached to a master that cannot be seen). More work is
needed to deal with topology changes and device relabeling.

Note: ABI break, but ABI_XINPUT_VERSION has NOT been bumped. Recompile input
drivers.
Revert "Xi: return BadImplementation for deviceids 256 and above"
This reverts commit 2b459f44f3.

Some files (notably those merged with MPX before XI2 came along) didn't use
a 'xi' prefix. This patch changes all of them to meaningful names.
