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.

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.

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.

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.

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

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.

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.

The protocol requires that if owner-events is true, then the delivery mask

DeliverGrabbedEvents does this already for us, checking first the delivery

cannot enter the states FREEZE_BOTH_NEXT_EVENT or FREEZE_NEXT_EVENT that
would be handled by DGE in any possible path here.
Bonus point - CheckPassiveGrabsOnWindows suddenly becomes a lot lesss

A direct grab on a slave device through XI2 detaches it, regardless of
whether the grab is sync or async. So this comment doesn't apply to XI2
anyway.
For XI1, aside from your life being miserable already, it doesn't matter as
XI1 does not have a concept of attachment. You can freeze a device and if
you don't freeze _all_ other devices at the same time, the master device can
still happily send events to the client.

A device with valuators but no keys is definitely a pointer device and needs
to be attached to the VCP. Otherwise, the class copying happens on the VCK
and the VCP isn't updated with the events that are to be sent through it.

On 64-bit systems, int and pointers don't have the same size, so GCC gives
warnings about casts between int and pointer types. However, in the cases
covered by this patch, it's always a value that fits in int being stored
temporarily as a pointer and then converted back later, which is safe.
Casting through the pointer-sized integer type intptr_t convinces the
