If an touch triggers an async button grab and that grab does not have the

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 -

Xi: Don't ActivateEarlyAccept POINTER_REGULAR listeners

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.

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

xfree86: Prefer fbdev to vesa

On UEFI machines you'd prefer fbdev to grab efifb instead of vesa trying
to initialize and failing in a way we can't unwind from.  On BIOS
machines this is harmless: either there is an fbdev driver and it'll
probably be more capable, or there's not and vesa will kick in anyway.

smartsched: Tweak the default scheduler intervals

A default timeslice of 20ms means a pathological client can ruin up to
two frames per scheduler tick.  And a fifth of a second is just insane.

Pick two different numbers out of the hat.  A 5ms slice means you can
probably keep up with two or three abusive clients, and letting it burst
to 15ms should give you about all the timeslice you need for a
fullscreen game (that's doing server-side rendering for some reason).

If you're running on a system with a 10ms granularity on SIGALRM, then
this effectively changes the intervals to 10ms and 30ms.  Which is still
better, just not as better.

I suspect this is about as good as we can do without actually going
preemptive, which is an entire other nightmare.
