Both may in some cases be called for a SD attached to a master keyboard. In
this case, we need to get the right master device (i.e. the pointer).

There's devices (e.g. some barcode readers) that have axes but no buttons.
When such a device sends a motion event, the valuator and button class is
copied into the master pointer (i.e. removing the button class).
So we need a couple of extra sanity checks for the button class to exist.

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.

ChangeDeviceId would actually overwrite the flags field if deviceid wasn't

There's no need for internal events to be a struct with a single nested

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)

Historically, if no input device was referenced in the ServerLayout,
the server would pick the first "mouse" device found in the xorg.conf.
This patch gives evdev, synaptics, vmmouse and void the same status. If
there is a section in the config file using this driver - use it as the core
pointer.
Device selection is in driver-order, not in config-order. If a "mouse"
device is listed after a "synaptics" device, the "mouse" device gets
preference. This replicates the original behaviour.
This code only takes effect if AllowEmptyInput is off and there is no core
pointer in the server layout.

In ProcXkbGetKbdByName, mrep.firstVModMapKey, .nVModMapKeys and
.totalVModMapKeys were not initialized, contained random values and caused
accesses to unallocated and later modified memory, causing
XkbSizeVirtualModMap and XkbWriteVirtualModMap to see different number of
nonzero values, resulting in writes past the end of an array in XkbSendMap.
This patch initializes those values sensibly and reverts commits 5c0a2088 and
6dd4fc46, which have been plain non-sense.

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 approach is broken anyway. DIPT only checked for the XInput type
"MOUSE" and the only user of this is xf86ActivateDevice when it sets the
Activate/DeactivateGrab functions.
Since synaptics and wacom set their own types, evdev only sets MOUSE for,
well, mice half the devices didn't have this set correctly anyway.
Instead, ActivatePointerGrab should be merged together with
ActivateKeyboardGrab.

A device can only be attached to a single master device. So instead of
looping and searching for the master device, we can just use dev->u.master

Both values need to fail the request, so we need to check them before
looping through the modifier masks. Otherwise, a wrong grab_window will
show up in each failed modifier return but not actually cause an error.
This function was deprecated in ef68273f5b
because it didn't take a device argument. The device argument was added in
1c7568b8a1 though, so the deprecation is
obsolete.

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.
Reproducible:
Configure a server that uses the keyboard driver with an invalid ruleset,
e.g. (Option "XkbRules" "foobar"). Ensure that Option "AllowEmptyInput" is
"off" in the ServerFlags or ServerLayout section. Start the server.
After failing to init the keymap, the server will try to clean up after the
device, double-freeing some xkb structs that have not been reset properly.

I really don't know what the purpose of this variable is or was, aside from
potentially clobbering up our key state since there's a path where it may be
used uninitialised.
Also, this means that xkbi->prev_state is now accessible from the DIX with
meaningful data.
