Xtst devices get this property assigned automatically so they can be
detected easily by a client.
The property is read-only.

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.
Requires changing the prototype to return status code instead of Bool.

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.
Refer to the XACE-Spec document in xorg-docs, section "Device Access."

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.

Revert "Xi: return BadImplementation for deviceids 256 and above"

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.

Some files (notably those merged with MPX before XI2 came along) didn't use

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.

Swapping the mask_len and then advancing the pointer by the swapped length

The maximum number of bytes is calculated by the mask len, and the mask len

zero-length masks are supposed to clear the device's mask.
ProcXISelectEvents passes these masks through directly, so we need to clear
the bits here if such a mask is supplied.

inputstr includes XI2proto.h for the sole purpose of XI_LASTEVENT.
However, using XI_LASTEVENT in the server is prone to errors, if the server
is recompiled against a newer version of the protocol it would bump this
variable and associates bits, including potential ABI.
This patch defines an XI2LASTEVENT for use in the server and removes the
XI2proto.h require. XI2LASTEVENT is the current value of XI_LASTEVENT.
This patch is required by components that require access to inputInfo
(currently xf86-video-geode and xf86-video-cirrus) but should not have a
require for the XI2 protocol.

Two issues that combined to false positives and false negatives.
- The checking for invalid bits must be performed when there are enough bits
that an event outside of LASTEVENT may be selected.
- The first invalid bit is LASTEVENT + 1, not LASTEVENT.

The protocol allows for 16 bit device ids, but the implementation doesn't
yet. We need to break the input ABI once more to shift the DeviceIntRec's
CARD8 to a CARD16, along with some changes in the privates.
Once that is done, revert this patch.

The server returned the minimum of major/minor each instead of the lower of
the combined major.minor version. As a result, a client reporting
3.0 and a server supporting 2.7, the return value would be 2.0 (the minimum
of both).
