Evdev devices do not have the bell proc set, but XTEST devices do. By
exiting early, the bell only rings if the last keyboard used was the XTEST
keyboard and hence the bell proc is still set on the master but not if an
evdev keyboard was used last.
The better approach here is to try to ring the bell on all devices attached
to this master device in case one or more actually do produce an audible
sound. That's also XKB's behaviour if XkbUseCoreKbd is specified as device
identifier.

When the input driver (like xf86-input-wacom) removes it's devices
during a call to UnInit, the CloseDownDevices() cannot handle it. The
"next" variable can become a pointer to freed memory.
The patch introduces order-independent device freeing mechanism by
remembering the already freed device ids. The devices can reorder any
time during freeing. No device will be double-freed - if the removing
failed for any reason; some implementations of DeleteInputDeviceRequest

Currently the XTEST device is limited to the same number of buttons the core

connected and is using a core client to fake button 8+ presses.
Rather than expecting all clients to fix themselves, just increase the
default number of buttons to 10, which is somewhat a compromise. Ideally,
the XTEST devices should adjust themselves to the highest number of buttons
available on the slave devices (like the master pointers already do), but

AlwaysCore and SendCoreEvents specify whether a device is to send core
events. A device that has either disabled is not supposed to send core
events.
With MPX/XI2, a device that is attached automatically sends core events when
the event is routed through the master device. Floating a slave device
disables core events by breaking the route.
This patch automatically floats devices that have coreEvents disabled in the
xorg.conf/HAL. This replicates the behaviour of a SendCoreEvents "false"
device in server 1.6 and earlier.

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.

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:

There's only two reasons for hierarchy events:
- device is added, removed, etc. In this case we want to send the event as
it happens.
- devices are added in a XIChangeDeviceHierarchy request. In this case we
only want one event cumulating all changes.
Rather than have one field per hierarchy change, XI2 has two fields - one
generic one and one per-device that include the device-specific flags.
This requires some funky handling for removed devices, but oh well.
Xephyr doesn't manually set Activate/DeactivateGrab for new devices,

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,

As proposed by Owen Taylor [1], the enter-leave event model needs to adjust
the events sent to each window depending on the presence of pointers in a
window, or in a subwindow.
The new model can be summarised as:
- if the pointer moves into or out of a window that has a pointer in a child
window, the events are modified to appear as if the pointer was moved out of
or into this child window.
- if the pointer moves into or out of a window that has a pointer in a parent
window, the events are modified to appear as if the pointer was moved out of
or into this parent window.
Note that this model requires CoreEnterLeaveEvent and DeviceEnterLeaveEvent to
be split and treated separately.

EnableDevice and DisableDevice both change the property too.
And enabled must be set to FALSE in AddInputDevice, the device is not enabled
yet.
X.Org Bug 18111 <https://bugs.freedesktop.org/show_bug.cgi?id=18111>
dev->enabled is a Bool. Bool is two bytes.
BOOL on the other hand is a protocol type and always 1 byte. So copy the value
into the one-byte type before passing it into XIChangeDeviceProperty.

The current code exposes to inconsistent updates, i.e. if handler N succeeds
but handler N+1 fails in setting the property, an error is returned to the
client although parts of the server now behave as if the property change
succeeded.
This patch adds a "checkonly" parameter to the SetProperty handler. The
handlers are then called twice, once with checkonly set to TRUE.
On the checkonly run, handlers _MUST_ return error codes if the property
cannot be applied. Handlers are not permitted to actually apply the changes.
On the second run, handlers are permitted to apply property changes.
Errors codes returned on the second run are ignored.
A property can only be deleted if any of the following is true:
- if a property is deletable and all handlers return Success.
- if a property is non-deleteable and the all handlers return Success AND the
delete request does not come from a client (i.e. driver or the server).
A client can never delete a non-deletable property.
For master devices, the ptraccel code could segfault on free since we'd be
dereferencing random memory. Callocing the valuatorClassRec is the easy fix.
Unplug a mouse, then warp the pointer and the warp pointer code will try
to update the position of the last slave device associated with the
master. That pointer will be stale and the X server will crash.

We may need more than one handler to deal with a property (e.g. one in the
driver, one in the DIX), so get the handlers into a linked list and call them
one-by-one. This is of course slightly less entertaining than the hilarious
WRAP/UNWRAP game we play in other parts of the server.
XIRegisterPropertyHandler/XIUnregisterPropertyHandler are the interface
drivers/the DIX should use to attach themselves to the device.
XIDeleteAllDeviceProperties destroys everything, including the handlers.
Basically just copied from randr properties, with minor changes only.
Each device supports arbitrary properties that can be modified by clients.
Modifications to the properties are passed to the driver (if applicable) and
can then affect the configuration of the device.
Note that device properties are limited to a specific device. A property set
on a slave device does not migrate to the master.

Using id = 0 only worked pre-MPX since XInput didn't allow XOpenDevice for the
core devices (0 and 1). Now we can now legally register for events so we may
overwrite our device-independent classes with the ones selected for the VCP.
So, increase the EMASKSIZE to MAX_DEVICES + 1 and use MAX_DEVICES as the ID
when we don't have a device.
Mixing usage where some parts of the code treated this field as a bitmask
and other parts as an array of card8 was wrong, and as the wire protocol
wanted bitmasks, it was less invasive to switch the newer counting code use
booleans.
Master devices track slave buttons by waiting for all slave buttons to be
released before delivering the release event to the client.
This also removes the state merging code in DeepCopyDeviceClasses -- that
code was changing master device state without delivering any events,
violating protocol invariants. The result will be that existing slave
button state which does not match the master will not be visible through the
master device. Fixing this would require that we synthesize events in this
function, which seems like a bad idea. Note that keyboards have the same
issue.

device->button->down used to be a 32-byte bitmask with one bit for each
button. This has changed into a 256-byte array, with one byte assigned for
each button. Some of the callers were still using this array as a bitmask
however, this is fixed with this patch.
Thanks to Keith Packard for pointing this out. See also:

We only have one set of default rules options in xkb. When the second keyboard
is brought up with Xkb options specified, these new options overwrite the old.
In future server generations, the rules used for the VCK are a mixture of the
default ones and ones previously specified for other keyboards. Simply
resetting the xkb default rules to NULL avoids this issue.
Reproducable by setting XkbLayout "de" and XkbVariant "nodeadkeys". In the
second server generation, the VCK has "us(nodeadkeys)". This again produces a
SIGABRT when the first key is hit.
I could not figure out why the SIGABRT happens. This patch is avoiding the
issue rather than fixing it.
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.
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.
Sometimes we didn't have a cursor when coming back from suspend. Reason was
that the suspend caused the server to lose the device that was attached to the
VCP, and a RemoveDevice() would then set the cursor to NULL.
Solution: only set the cursor to NULL if we actually own the sprite.
We pass in the client that wants to create the device anyway, lets use the
parameter instead of hardcoding the serverClient.
Wow. I hope this is merge detritus, otherwise it'd be a sign that I didn't
have enough coffee that day.
When a new device is added, calculate the event size needed if a DCCE event is
sent and set the EQ's event size to this minimum. This avoids reallocs when a
event is sent (which may happen during a SIGIO).
