this window then crashed the server.

The sourceid for enter/leave events as a result of pointer motion is the ID
of the slave device. The sourceid for those as a result of a grab activating
is the device itself.

If a passive enter or focus in grab activates, send additional enter or
focus events with mode XIPassiveGrabNotify to the grabbing client.
Likewise, if the grab deactivates, send additional leave or focus out
events.

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).
This commit moves the focus handling from events.c into enterleave.c and
implements a model similar to the core enter/leave model.

This commit also gets rid of the focusinout array in the WindowRec, ditching
it in favour of a local array that keeps the current focus window for each
device.

Instead of keeping a flag on each window for the devices that are in this
window, keep a local array that holds the current pointer window for each
device. Benefit: searching for the first descendant of a pointer is a simple
run through the array.

The old model was implemented based on a misunderstanding of NotifyVirtual and
NotifyNonlinearVirtual events. It became complicated and was broken in some
places [1]. This patch wipes this model completely.
A much simplified implementation is provided instead. Rather than a top-down
approach ("we have a tree of windows, which ones need to get which event")
this one uses a step-by-step approach. For each window W between A and B
determine the pointer window P as perceived by this window and determine the
event type based on this information. This is in-line with the model described
by Owen Taylor [2].

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.

FirstPointerChild: Return the first child that has a pointer within its
boundaries.
FirstPointerAncestor: return the first ancestor with a child within its
boundaries.
These are required for the updated enter/leave model.

Device events always need to be delivered, core events only in some cases.
Let's keep them completely separate so we can adjust core event delivery.
