If an touch triggers an async button grab and that grab does not have the
ButtonReleaseMask set, the TouchEnd is never delivered, deliveries is 0 and
the grab is never deactivated.
If the grab is pointer async and keyboard sync, the keyboard events are stuck
in EnqueueEvent until some other pointer event terminates the grab.
Change this to check for the number of listeners. If we're about to deliver a
TouchEnd to a passive pointer grab, the number of listeners is already 1 -
pointer grabs always accept so other listeners were removed.

Bug #71878 describes a bug resulting in the server ceasing to respond to
keyboard input after a touch event. The problem might be the following:
DeliverTouchBeginEvent tries to deliver an event to a listener of type
LISTENER_POINTER_REGULAR, taking the following if branch,
if (listener->type == LISTENER_POINTER_REGULAR ||
listener->type == LISTENER_POINTER_GRAB) {
rc = DeliverTouchEmulatedEvent(dev, ti, ev, listener, client, win,
grab, xi2mask);
if (rc == Success) {
listener->state = LISTENER_IS_OWNER;
/* async grabs cannot replay, so automatically accept this touch */
if (dev->deviceGrab.grab &&
dev->deviceGrab.fromPassiveGrab &&
dev->deviceGrab.grab->pointerMode == GrabModeAsync)
ActivateEarlyAccept(dev, ti);
}
goto out;
}
DeliverTouchEmulatedEvent succeeds. The deviceGrab meets all
three of the conditions of the inner if, enters
ActivateEarlyAccept which then fails due to,
BUG_RETURN(ti->listeners[0].type != LISTENER_GRAB &&
ti->listeners[0].type != LISTENER_POINTER_GRAB);
That is, despite listener->type == LISTENER_POINTER_REGULAR. With my
non-existent knowledge of XINPUT, it seems like the solution here
might be to only ActivateEarlyAccept when listener->type ==
LISTENER_POINTER_GRAB.

We're meant not to call these by name due to ABI. Rather than try to
generate a bunch of little stub functions that do the lookup, just
inline it all directly into the calling function.
This does not cache results. That's fine, this is not a performance
path, and if we're atop WGL then we effectively have to do this every
time anyway because wglGetProcAddress results are context-dependent.

v7: Don't bother making resources for the backing listeners. [keithp]
This is now slightly unlike how other resources are xineramified. We
create N+1 internal damage listeners, one that's a real resource and
reflects the protocol view, and then one per backend screen where the
report function piles onto the protocol view. The internal listeners
are not stored in the resource database directly, they just hang off the
xinerama resource. We don't wrap Subtract at the dispatch level, but we
do extend it for the Xinerama case to clip to the root window geometry.
As a result of the N+1 design here, the damage reports we generate are
not quite minimal. However they are indistinguishable from sequential
rendering events happening before the client hears damage, and we don't
need to add a post-dispatch callback just for this one extension.
Add is probably (still) somewhat broken since it will only hit screen 0,
but Add really only exists for DRI1's sake, and DRI1 disables itself
with Xinerama enabled anyway. In the absence of a use case, I'm leaving
it unwrapped under Xinerama; if someone wants to define how it ought to
work, be my guest.

Say you have two 800x600 screens left/right of each other. A window
that's 200x200 at +700+0 in protocol coordinate space will appear to be
at -100+0 in the coordinate space of the right hand screen. Put another
way: windows are in the coordinate space of their root window pixmap.
We weren't doing this translation for the COW, so when rendering came in
to it you'd see the top-left chunk of the COW on all screens. Cool
effect and all, but wrong.
