If a client passes a section of memory via file descriptor and then
subsequently truncates that file, the underlying pages will be freed
and the addresses invalidated. Subsequent accesses to the page will
fail with a SIGBUS error.
Trap that SIGBUS, figure out which segment was causing the error and
then allocate new pages to fill in for that region. Mark the offending
shared segment as invalid and free the resource ID so that the client
will be able to tell when subsequently attempting to use the segment.

APM support in the Xserver was used to restore the console mode
prior to a power management event. This was to ensure the mode
upon suspend/resume was one that the system firmware or kernel

APM support is now largely obsolete, KMS drivers don't require a
mode restoration anyhow. Therefore it should be possible to disable
this feature.

The time between the idle reset and the IdleTimeWakeupHandler to be called is
indeterminate. Clients with an PositiveTransition or NegativeTransition alarm
on a low threshold may miss an alarm.
Work around this by keeping a reset flag for each device. When the
WakeupHandler triggers and the reset flag is set, we force a re-calculation of
everything and pretend the current idle time is zero. Immediately after is the
next calculation with the real idle time.
Relatively reproducible test case: Set up a XSyncNegativeTransition alarm for
a threshold of 1 ms. May trigger, may not.

Obsolete since 4bc2761ad5. This struct
existed so copying a passive grab could be simply done by
activeGrab = *grab
and thus have a copy of the GrabPtr we'd get from various sources but still
be able to check device->grab for NULL.
Since 4bc2761 activeGrab is a pointer itself and points to the same memory
as grabinfo->grab, leaving us with the potential of dangling pointers if
either calls FreeGrab() and doesn't reset the other one.
There is no reader of activeGrab anyway, so simply removing it is
sufficient.
Note: field is merely renamed to keep the ABI. Should be removed in the
future.

A sync grab is the owner once it gets events. If it doesn't replay the
event it will get all events from this touch, equivalent to accepting it.
If the touch has ended before XAllowEvents() is called, we also now need to
send the TouchEnd event and clean-up since we won't see anything more from
this touch.
Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
If a device is frozen in results to a grab, we need to enqueue the events.
This makes things complicated, and hard to follow since touch events are now
replayed in the history, pushed into EnqueueEvent, then replayed later
during PlayReleasedEvents in response to an XAllowEvents.
While the device is frozen, no touch events are processed, so if there is a
touch client with ownership mask _below_ the grab this will delay the
delivery and potentially screw gesture recognition. However, this is the
behaviour we have already anyway if the top-most client is a sync pgrab or
there is a sync grab active on the device when the TouchBegin was generated.
(also note, such a client would only reliably work in case of ReplayPointer
anyway)

If we're about to abort, we're already in the signal handler and cannot call
down to the default device cleanup routines (which reset, free, alloc, and
do a bunch of other things).
Add a new DEVICE_ABORT mode to signal a driver's DeviceProc that it must
reset the hardware if needed but do nothing else. An actual HW reset is only
required for some drivers dealing with the HW directly.
This is largely backwards-compatible, hence the input ABI minor bump only.
Drivers we care about either return BadValue on a mode that's not
DEVICE_{INIT|ON|OFF|CLOSE} or print an error and return BadValue. Exception
here is vmmouse, which currently ignores it and would not reset anything.
This should be fixed if the reset is required.
