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."

Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.
Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.
Symbols in the sdk (or referenced in sdk macros), but not defined
anywhere include:

For two axes [a, b] and [x, y] (inclusive), the formula to scale point P(ab)
to (x,y) is:
(P - a)/(b - a) * (y - x) + x
And the whole end result rounded of course to get the integer we need.

Button events were mapped once in GetPointerEvents and then again in
UpdateDeviceState. While it might make sense to just fix up UpdateDeviceState,
it turns out to be better to leave the raw button number in the event because
DGA reports raw device events without button translation, and so when it calls
UpdateDeviceState, the button down counts get scrambled and buttons get stuck
down.

The core protocol requires absolute values and it's a bit hard to get them if
we only have relative ones in the history. Switch the motion history to
absolute, and if we really need the relative values, we can probably generated
them from the abs. ones in the future.
Add each event to the master's MH as well as to the SDs. In the MD, store
min/max and the actual value. When retrieving the MH, rescale all coordinates
to the current coordinate range and only post those valuators that are
currently active on the device.
Since we can't predict how many valuators may be in a future SD attached to an
MD, we need to preallocate a history buffer that is large enough to keep
MAX_VALUATORS coordinates per event.
In addition, the history buffer needs to memorize the coordinate ranges at the
time, thus requiring MDs to store (min_val, max_val, current_val, time)
instead of (current_val, time) for each motion history entry.
This commit only fixes the allocation.
With the MD/SD device hierarchy we need control over the generation of the
motion history as well as the conversion later before posting it to the
client. So let's not let the drivers change it.
No x.org driver currently uses it anyway, linuxwacom doesn't either so dumping
it seems safe enough.
master->last.valuator[x] for x > 2 is undefined. For all other devices, it's
the respective device's last valuators.
If the lastSlave did not have a valuator that is to be updated now, it is
reset to 0.
In GPE, we don't care about the device mode. Let's put the absolute values
into the deviceValuator event and worry about relative valuators on the other
side of the EQ.
Assuming master->last.valuators is in screen coords, SD's are always in device
coordinates.
1. If an event comes in, scale masters->last to the device, drop into device's
last->valuators.
2. Apply motion from the actual event
3. Scale back to screen coords, check if we may need to cross screens
4. Drop screen coords into master->last
5. Rescale to device coords, drop into deviceValuator event and SD->last
6. Drop screen coords into ev->root_x/y
Whoopee...
During GetPointerEvents (and others), we need to access the last coordinates
posted for this device from the driver (not as posted to the client!). Lastx/y
is ok if we only have two axes, but with more complex devices we also need to
transition between all other axes.
ABI break, recompile your input drivers.
Changed all the checks for x&y valuator so the more complex
calculation is only made once.
Added TODOs for valuator/axis 2 and above for future correct
handling of relative reporting of these.

valuators[] is passed from the DDX. Depending on the device mode, update it
with either absolute values or relative values. The deviceValuator event sent
to the client will then contain the respective values.
This isn't quite finished yet, but at least it gives us the ability to use a
tablet as a normal mouse - with all the scaling in place.

XQuartz was crashing because the Appkit thread was trying to GetXXXEvents while the Xserver thread was exiting.

that are usually sent from the input devices.

The latter is used to increase the amount of allocated memory for the event
list. This will be needed for ClassesChangedEvents that can be of more or less
arbitrary size (larger than 32 anyway).
Rather than letting the DDX allocate the events, allocate them once in the DIX
and just pass it around when needed.
DDX should call GetEventList() to obtain this list and then pass it into
Get{Pointer|Keyboard}Events.
Relative events that generates both core and extention
events will have its axis cliped and screen changed by
miPointerSetPosition when the events are processed. For
absolute and non core-generating relative events the
axis must be clipped if we shouldn't end up completely
outside the defined ranges (if any).
Don't use a possitive value as a marker for if a max-value
is defined on the valuators. Use the existence of a valid
value range instead. This will also make it possible to
define arbitrary start and end-values for min and max as
long as min < max.
(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.

(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.
Initialise num_events to 1, so we always send a proximity event, and then
optionally valuator events. Also make sure mieq can deal with valuator
events sent after proximity events.
We free the ValuatorClassRec quite regularly. If a SIGIO is handled while
we're swapping device classes, we can bring the server down when we try to
access lastx/lasty of the master device.
Turns out it's really really hard synchronising device state across multiple
duplicated events if they all share the same struct. So instead of doing so,
when the SD changes deep-copy all it's classes into the MD. The MD then has
the same capabilities, but the state can be set separately. This should fix
xkb, key state, repeat etc. problems.
Updating the device state allows us to remove the SwitchCoreKeyboard from the
event gathering, it's all done during event processing now.
If a slave device is attached to a master device, then we need to send a
mapping notify to the client.
Mapping notify needs to be sent if
- different slave device but on same master
- different master
This gives you funny behaviour with the ClientPointer. When a
MappingNotify is sent to the client, the client usually responds with a
GetKeyboardMapping. This will retrieve the ClientPointer's keyboard mapping,
regardless of which keyboard sent the last mapping notify request. So
depending on the CP setting, your keyboard may change layout in each app...
Each time a different slave device sends through a master, an
DeviceClassesChangedEvent is enqueued. When this event is processed, all
classes of the matching master device are changed, and the event is sent to
the clients.
Next time the master is queried, it thus shows the evclasses of the last slave
device. The original classes are stored in the devPrivates.
TODO: if all slave devices are removed, the master's original classes need to
be restored.
For pointers: don't try to set master->valuator fields if there is no master.
For keyboards: check if device is valid before trying to access the fields in
miPointerGetScreen (btw. this disables DGA events for floating keyboards).
Also stop the hideous number of ErrorFs if we request the paired device for a
floating dev.
Let the drivers only generate XI events and put those into the event queue.
When processing events, generate core events as needed. This fixes a number of
problems with XKB and the DIX in general.
The previous approach was to put core events and XI events as separate events
into the event queue. When being processed, the server had no knowledge of
them coming from the same device state change. Anything that would then change
the state of the device accordingly was in danger of changing it twice,
leading to some funny (i.e. not funny at all) results.
Emulating core events while processing XI events fixes this, there is only one
path that actually changes the device state now. Although we have to be
careful when replaying events from synced devices, otherwise we may lose
events.
Note: XI has precedence over core for passive grabs, but core events are
delivered to the client first.
