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.

The version in eventconvert.c was half broken and for some reason we ended
up with a second version in exevents.c (which works). Move it over to where
it belongs and call EventToXI2 instad of having a custom function for it.

If a new device posts an event while the DCE is in the queue, getting the
data from the device may result in invalid memory access.
X.Org Bug 23100 <http://bugs.freedesktop.org/show_bug.cgi?id=23100>
Unlike Enter/Leave events generated by a device pushing the pointer around,
a device doesn't change focus all by itself. It's a result of a
SetInputFocus call, a window becoming unviewable or a grab activating. As
such, the sourceid for focus events is always the deviceid itself.

Use enum EventType instead of ints. This requires a load of default

XI1 only uses 7 bits for deviceids, bit 8 is used for the MORE_EVENTS flag

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.

Xtst devices get this property assigned automatically so they can be

Rather than storing a simple boolean in the devPrivate for XTest devices,
store the actual master device's id (since it is constant for the life of
the device anyway).
Callers should use GetXtstDevice now instead of digging around in the
devPrivates themselves.
This patch allows for a cleanup in the creation of new master devices since
GetMaster and GetXtstDevice spare the need for loops, IsPointer checks and
similar.

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.

Presumably, some intelligent, XI2-aware management app will be calling
XISetClientPointer on behalf of other clients; this check makes sure
the target client has permission on the device.

New access modes are being passed to the device access hook for XI2:
DixCreateAccess for creating a new master device;
DixAdd/RemoveAccess for attaching/removing slave devices to a master; and
DixListProp/GetProp/SetPropAccess for device properties.

Master devices provide the union of all attached slave devices' buttons,
i.e. the number of buttons on the master device is always the number of
buttons of the slave device with the highest number of buttons. When slaves
are attached or detached, the master device adjusts the button number to
reflect the new buttons.
On a slave switch, this slave's button labels are copied into the master (up
to slave->num_buttons). The remaining button labels (if any) stay as they
are. Thus, if any of the higher buttons is still pressed, it reflects the
label of the last pressed device that provided this button.
If two devices press the same button and it is differently labelled the last
pressed one will be reflected in the master device.

The previous code would always skip the last valuator due to a wrong
upper boundary in the loop. last_valuator is the index of the last set
valuator - which also means it must be initialized to -1, not 0.

If SetClientPointer fails, the only reason may be that the device is not a
pointer or that the device is an SD. Return BadDevice instead of BadAccess.
(BadAccess is a leftover from the early times of the ClientPointer
implementation when only one client was allowed to set it).
If the window parameter doesn't name a valid window or client, return
BadWindow.
Finally, allow both master keyboards and master pointers as deviceid.
