c360b3eb1d Let CheckPassiveGrabsOnWindow callers check if device is already grabbed.
CheckDeviceGrabs checked all the ancestors of the window containing this
device's pointer even if no new grabs could possibly apply due to the
device already being grabbed.

ActivateFocusInGrab and ActivateEnterGrab already checked whether they
should break an existing grab, and then set up an event that was
completely ignored if they didn't actually break the grab.

In both cases, just do what we would have done eventually anyway--return
FALSE from CheckPassiveGrabsOnWindow's caller--but do it sooner.

1884db430a Revert "dix: use the event mask of the grab for TryClientEvents."
Behaviour of earlier X servers was to deliver the ButtonPress event
unconditionally, regardless of the actual event mask being set. This is
documented in the protocol:
"This request establishes a passive grab.  In the future, the pointer is
actively grabbed as described in GrabPointer, the last-pointer-grab time is
set to the time at which the button was pressed (as transmitted in the
ButtonPress event), and the ButtonPress event is reported if all of the
following conditions are true:
    <list of conditions, event mask is not one of them>"

Thus, a GrabButton event will always deliver the button press event, a
GrabKey always the key press event, etc. Same goes for XI and XI2.

Reproducible with a simple client requesting a button grab in the form of:
    XGrabButton(dpy, AnyButton, AnyModifier, win, True, ButtonReleaseMask,
                GrabModeAsync, GrabModeAsync, None, None);

On servers before MPX/XI2, the client will receive a button press and
release event. On current servers, the client receives only the release.
Clients that expect the press event to be delivered unconditionally.

XTS Xlib13 XGrabButton 5/39 now passes.

This reverts commit 48585bd1e3.
Effectively reverts commit 1c612acca8 as well,
the code introduced with 1c612 is not needed anymore.

2dc138922b Rename region macros to eliminate screen argument
This is a combination of a huge mechanical patch and a few small
fixups required to finish the job. They were reviewed separately, but
because the server does not build without both pieces, I've merged
them together at this time.

The mechanical changes were performed by running the included
'fix-region' script over the whole tree:

$ git ls-files | grep -v '^fix-' | xargs ./fix-region

And then, the white space errors in the resulting patch were fixed
using the provided fix-patch-whitespace script.

$ sh ./fix-patch-whitespace

Thanks to Jamey Sharp for the mighty fine sed-generating sed script.

The hand-done changes involve removing functions from dix/region.c
that duplicate inline functions in include/regionstr.h, along with
their declarations in regionstr.h, mi.h and mispans.h.

a83cff9f4d Move each screen's x/y origin into ScreenRec.
Many references to the dixScreenOrigins array already had the
corresponding screen pointer handy, which meant they usually looked like
"dixScreenOrigins[pScreen->myNum]". Adding a field to ScreenRec instead
of keeping this information in a parallel array simplifies those
expressions, and eliminates a MAXSCREENS-sized array.

Since dix declared the dixScreenOrigins array, I figure allocating a
screen private for these values is overkill.

e291c56182 Return an appropriately-typed error from dixLookupResourceByType.
Rather than always returning BadValue, associate an error status like
BadWindow with a resource type like RT_WINDOW, and return the
appropriate one for the requested type.

This patch only touches the core protocol resource types. Others still
return BadValue and need to be mapped appropriately.

dixLookupResourceByType can now return BadImplementation, if the caller
asked for a resource type that has not been allocated in the server.

4b9600a416 Make WriteEventsToClient/WriteToClient no-op on fake or dead clients.
This matches the test in TryClientEvents, and is a superset of tests
done by the callers of these functions. The consequence of forgetting
these tests is a server crash, so they're always desirable. In my
opinion, it's better to not require the callers to remember to do these
checks.

For callers that don't do very much work before calling WriteToClient or
WriteEventsToClient, I've removed the redundant checks.

hw/xquartz/xpr/appledri.c has an interesting case: While its check for
"client == NULL" appears redundant with the test in WriteEventsToClient,
it dereferences client to get the sequence number.

9ddbb03fa5 dix: Fix crash in DeliverGrabbedEvents.
If both devices are synchronously grabbed, first with a GrabPointer, then
with a GrabKeyboard (GrabModeSync on both), sync.other of each device points
to the grab of the respective other device.

If the keyboard is then thawed through a AllowSome request, the VCK's
sync.other is reset to NULL. Subsequently, an event on the VCP would crash
the server when dereferencing sync.other on the VCP.

The check's purpose is to compare if the other device is grabbed by the same
client, which should be checked by accessing (dev->deviceGrab->grab->resource).
A check of the server-1.3 sources confirms that.

XTS test case: Xlib13 XAllowEvents 20.

For XI1, aside from your life being miserable already, it doesn't matter as

you don't freeze _all_ other devices at the same time, the master device can
still happily send events to the client.

0c0ef42292 dix: Remove temporary detachment of slave devices.
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.

a7e23a79c1 Xi: Add support for Enter and FocusIn grabs.
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.

b12d302df8 Input: rename DeviceIntRec->isMaster to ->type.
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).
