Fixes xmodmap changes to modifiers to stop corrupting modifier maps
Previous code had two bugs:
- the code to increment mod was after the code to continue if no
modifier was set, so mod wouldn't be incremented for modifiers
with no keys mapped to them (such as if you called
xmodmap -e 'clear Lock')
- the value it set in the modifier map was the raw modifier number,
not the bitmask value for that modifier

The XGetImage man page states:
If the drawable is a window, the window must be viewable, and it must be the
case that if there were no inferiors or overlapping windows, the specified
rectangle of the window would be fully visible on the screen and wholly
contained within the outside edges of the window, or a BadMatch error
results. Note that the borders of the window can be included and read with
this request.
However, the server was only checking the requested region against the screen
bounds, allowing XGetImage requests to read pixels outside the bounds of a
window's ancestors. Normally, this would just read other pixels from the
screen, but if one of the ancestor windows is redirected, the window's backing
pixmap may be smaller than the window itself.
This change checks the region against the window's bounding drawable, which is
either the screen pixmap, a redirected window's backing pixmap, or the root
window for servers that don't support GetWindowPixmap.

Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
Previously, an active grab on an attached slave device would send the device
floating for the duration of the grab. This breaks existing XI applications
(e.g. the GIMP) since they grab all devices automatically - resulting in the
loss of control over the VCP.
The behaviour of extended input devices during a grab in relation to the
core pointer is not specified in the XI protocol specification.
The removal of the temporary detachment restores the behaviour of extended
input devices as present in currently released servers - even if a device is
grabbed, an event from this device will result in an event from the core
pointer.

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.

A passive XI2 grab always uses the paired master device as a modifier
device. After issuing a passive grab, the slave may be reattached to a
different master and hence the modifier device may change.
Rework addresses two issues:
- storing the master device's pointer is a bad idea, we need to store the ID
of the device in case it disappears during the grab.
- restoring the old master did not actually reattach the device. Fixed now.
grab->type is the device type and XI2 types overlap with core events (being
less than GenericEvent). Thus, for passive grabs the grab device would be

Enter grabs are checked for in CheckMotion(), each time the sprite window
changes the current grab is deactivated (if applicable) and the new grab is
activated (if applicable). Exception - if the grab is on a parent window of
the current window since we keep the grab across descendants.
Since CheckMotion() may change the grab status of a device, we mustn't get
"dev->deviceGrab.grab" in ProcessOtherEvents until after CheckMotion().
FocusIn grabs are checked in much the same manner.
The event delivery for grabs replaces the NotifyNormal on window change with
a NotifyGrab on window change. Note that this happens before the grab
activates, so the EnterNotify(NotifyGrab) is still delivered to the window,
not to the grabbing client. This is in line with the core protocol semantics
for NotifyGrab 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).
dev->u.lastSlave was not signal safe since it was accessed by the DIX and
during signal handling.

There's only two reasons for hierarchy events:
- device is added, removed, etc. In this case we want to send the event as

- devices are added in a XIChangeDeviceHierarchy request. In this case we

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.

Only ever change the button map on the device we actually care about, not the
attached SDs, not the current MD of the device.

Don't pass xEvent* and count through to processing, pass a single
InternalEvent.
Custom handlers are disabled for the time being. And for extra fun,
XKB's pointer motion emulation is disabled. But stick an error in there so
that we get reminded should we forget about it.

With the API change, we can now purge the XI conversion from POE.
Note: this commit breaks DGA even more.

deviceGrab.sync.event is now an internal event, and CheckDeviceGrabs and
friends is changed over.
Note that this currently breaks some frozen grabs. See towards the end of
ComputeFreezes().

Note that we're only partially switched to internal events. The event in the
devices' event queue (dev->deviceGrab.sync.event) is still an XI event. The
events in syncEvents are InternalEvents only now.
This also implies fixing CheckVirtualMotion to work with internal events.

Get rid of the deviceValuator processing and a few other things, but still
drop back into XI before checking device grabs or doing anything else.
NoticeEventTime now needs to take InternalEvents, and while we're at it,
change NoticeTime from a macro to a function.

Note that this breaks DGA. Life is tough.
EnqueueEvent is a somewhat half-baked solution, we immediately drop back into
XI and store them. But it should in theory work.

Don't let the dcce be random data.
Before dropping down into the DIX, convert back into XI events. This is a
temporary solution only, until the DIX is capable of handling InternalEvents
anyway.

This gets rid of the nevents parameter, InternalEvents are always a single
item per event. Also remove the special DeviceValuator handling in both
enqueueing and dequeueing.
Custom callback handlers are now broken until fixed.
For bisectability, we copy the InternalEvent back into the XI required during
POE and friends. Consider this a temporary solution.
Note: Because of misc linker bonghits, Xvfb won't link in this revision.

GPE, GKVE, GProxE generate InternalEvents now.
DeviceClassesChangedEvents generates an InternalEvent now, but incomplete! We
need to tack on the information about the new SD in the ClassesChanged events.
Note: To make the progress bisectable, we drop back into XI events at the end of the
Get*Events functions. So the rest of the server still uses XI events.

Until the InternalEvents are used throughout the server, we can use this one
to drop us back into XI la-la land where every event is the wire format.

Convert from an InternalEvent type to the matching core/XI type. Currently
only for a few events, those we actually need in the server.

Rather, modify the two callers to call separately for the two different.
events. Unexport SetMaskForEvent too.
And while we're at it, get rid of the MotionFilter macro, because it's one
half confusing and one half pointless.

The algorithm is split in a 2D-specific and a general part.
This potentially allows to accelerate more than just screen motion.
A state machine is intoduced to make code more explicit and readable.
It also improves handling of 'phase 1' mickeys when axial correction
kicks in (corner case).
