This is a significant shift in how input events are perceived. The common
approach was to treat a core event as a different entity than the XI event.
This could result in the XI event being delivered to a different client than
the core event. This doesn't work nicely if they come from the same device.
Instead, we treat an input event as a single event, that is delivered through
two separate APIs. So when delivering an event, we first try the XI event,
then the core event. If the window want's neither, we go to the parent and
repeat. Once either core or XI has been delivered, the processing stops.
Important: Different to the previous method, if a client registers for core
button events, the parent window will not get XI events. This should only
cause problems when you're mixing core and XI events, so don't do that!
Generic events don't fit into this yet, they cause me headaches.
This should restore the correct passive grab processing. When checking for
passive grabs, the core event is emulated and we check first for XI grabs on
the window, then for core grabs. Regardless of which event activates the grab,
the XI event is stored in the device's EQ.
When replaying the event, we take the XI event and replay it on the next
window, again including the emulation of the core event.
If two devices are attached to the same master device, pressing button 1 on
each of them leads to two button presses from the same device. Some apps
really don't like that.
So we just put a counter in place and only send the first press and the last
release.
(first_valuator + num_valuators) must never be larger than the number of axes,
otherwise DIX freaks out. And from looking at libXI, anything larger than 6 is
wrong too.

Also fixed DarwinEQEnqueue to match changes to the callback
And also use dpmsstubs.c rather than copying the code into darwin.c

xf86CrtcRotate() is called by randr 1.2 drivers via xf86CrtcSetMode() or xf86SetDesiredModes()
during ScreenInit() at which point pScrn->pScreen is not set. If a user specifies a rotation
in their config file pScrn->pScreen is dereferenced and boom.
8 bit color still doesn't work, but the -depth command line argument now works properly.

The window ID includes the client ID anyway, so we might as well just look up
the client directly instead of trying to get the window first and the client
from the window.
This also fixes a possible issue with XACE. If the client had permission to
write on the client but not on the window, the previous approach would have
failed.
All the rest of XI uses rc and returns rc in case of error, so make
mpx-related stuff comply. This stops the rest of XI sending the error
manually.
This is just a cosmetic change to be in line with the rest.
