merge with code cleanup from master
GetPointerEvents treats events in the same way as XINPUT devices when flag
has POINTER_MULTIPOINTER set.
xfree86/common:
added XI86_MP_DEVICE flag and parsing in xf86ProcessCommonOptions
added POINTER_MULTIPOINTER define. Is used in xf86PostMotionEvent and
xf86PostButtonEvent for the flags that are passed into GetPointerEvents()
global:
added flags to configure.ac to enable/disable MPX define
added flags to dix-config.h.in to define MPX
Remove keymap copy from GetKeyboardValuatorEvents, as
SwitchCoreKeyboard now takes care of this for us.
Remove unused variable and function prototype.
Update comments to be as informative as possible.
Move the keymap copying to event processing time (in
ProcessInputEvents), instead of being at event enqueuing time.
Break SetCore{Pointer,Keyboard} out into separate functions.
Change mieqEnqueue to take a device pointer, that asks for the
_original_ device associated with this event.
