Currently the root coordinates may fall into ]-1..0] if the subpixel
remainder is less than 0. Screen coordinates mustn't go below 0, so use
miPointerSetPosition to cap off the remainder if the coordinates are below
0.
This is cheating a bit, a more comprehensive solution to deal with subpixels
correctly when crossing screens is needed. For now, this'll do.

Now that all event queues hold internal events only, they never need
to be resized. Resizing them led to memory corruption as they would
get sized for an appropriate xEvent, not an internal event.

DCEs are now processed when sent throught the master device, not when sent
through the slave device. This includes a removal of some un-used (or partly
used) fields in the DCE itself to something more self-explanatory.
TODO: if a device has events queued and its attachment is changed, the DCE
is silently dropped now. Instead, it should be generated as soon as the
first event after the attachment is sent.

InternalEvents shouldn't be used anywhere outside the X server itself. Split
up into events.h for opaque typedefs for the events needed by various
headers and eventstr.h for the actual struct definitions.
eventstr.h must only be included by code that requires internal events and
is not part of the SDK.

Copying all classes into the master device has drawbacks for hybrid devices
(devices that are both mice and keyboards). If such a device posts an event,
it's key classes are moved into the VCP. The key event itself is unaffected
by keyboard grabs and the like.
Partial class copying copies depending on the event and copies the classes
into the right master device (i.e. the VCK for key events, the VCP for
pointer events).

For hybrid devices (keys + buttons/axes) the attached master device is
generally the wrong one. One shouldn't post a button event through a
keyboard and vice versa.
GetMaster(dev) returns the right master device for the given type needed.
This may be the MD paired with this device's MD.

isMaster is not enough as long as we differ between master pointers and
keyboard. With flexible device classes, the usual checks for whether a
master device is a pointer (currently check for ->button, ->valuators or
->key) do not work as an SD may post an event through a master and mess this
check up.
Example, a device with valuators but no buttons would remove the button
class from the VCP and thus result in the
IsPointerDevice(inputInfo.pointer) == FALSE.
This will become worse in the future when new device classes are introduced
that aren't provided in the current system (e.g. a switch class).
This patch replaces isMaster with "type", one of SLAVE, MASTER_POINTER and
MASTER_KEYBOARD. All checks for dev->isMaster are replaced with an
IsMaster(dev).
dev->u.lastSlave was not signal safe since it was accessed by the DIX and
during signal handling.
Replaced with:
'dev->last.slave' for the signal handler's lastSlave (used to generate
DeviceChangedEvents), .
'dev->u.lastSlave' for the DIX lastSlave (currently only used in
change_modmap)

If the device is disabled ("off"), it must not send events to a client.
The driver shouldn't send events in that case anyway, but just to make sure
we simply drop events coming while the device is disabled.

This gets rid of the nevents parameter, InternalEvents are always a single
item per event. Also remove the special DeviceValuator handling in both
enqueueing and dequeueing.
Custom callback handlers are now broken until fixed.
For bisectability, we copy the InternalEvent back into the XI required during
POE and friends. Consider this a temporary solution.

GPE, GKVE, GProxE generate InternalEvents now.
DeviceClassesChangedEvents generates an InternalEvent now, but incomplete! We
need to tack on the information about the new SD in the ClassesChanged events.
Note: To make the progress bisectable, we drop back into XI events at the end of the
Get*Events functions. So the rest of the server still uses XI events.

If the MD's lastSlave was a devices with custom axes ranges, then a
WarpPointer would position the cursor at the wrong location. A WarpPointer
request provides screen coordinates and these coordinates were scaled to the
device range before warping.
This patch consists of two parts:
1) in the WarpPointer handling, get the lastSlave and post the event through
this device.
2) assume that WarpPointer coordinates are always in screen coordinates and
scale them to device coordinates in GPE before continuing. Note that this
breaks device-coordinate based XWarpDevicePointer calls (for which the spec
isn't nailed down yet anyway) until a better solution is found.

positionSprite needs to scale to screen coordinates and in the process of
doing so alters dev->last.valuators[0:1]. Drop the real coordinates back after
finishing and before updating the motion history. This way, we don't push the
screen coordinates into the motion history.

A grep on xorg/* revealed there's no consumer of this define.
Quote Alan Coopersmith:
"The consumer was in past versions of the headers now located
in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h,
all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.
Looks like Xproto.h dropped them by X11R6.3, which didn't have
the #ifdef's anymore, so these are truly ancient now."
