Relative events that generates both core and extention
events will have its axis cliped and screen changed by
miPointerSetPosition when the events are processed. For
absolute and non core-generating relative events the
axis must be clipped if we shouldn't end up completely
outside the defined ranges (if any).

Don't use a possitive value as a marker for if a max-value
is defined on the valuators. Use the existence of a valid
value range instead. This will also make it possible to
define arbitrary start and end-values for min and max as
long as min < max.

Because our "popen" implementation uses stdio, and because nobody's stdio
library is capable of surviving signals, we need to make absolutely sure
that we hide the SIGALRM from the smart scheduler. Otherwise, when you
open a menu in openoffice, and it recompiles XKB to deal with the
accelerators, and you popen xkbcomp because we suck, then the scheduler
will tell you you're taking forever doing something stupid, and the
wait() code will get confused, and input will hang and your CPU usage
slams to 100%. Down, not across.
If input processing is frozen, only wrap realInputProc: don't smash
processInputProc as well. When input processing is thawed, pIP will be
rewrapped correctly.
This supersedes the previous workaround in 50e80c9.

Composite uses an unmap/map cycle to trigger backing pixmap allocation
and cliprect recomputation when a window is redirected or unredirected.
To avoid protocol visible side effects, map and unmap events are
disabled temporarily. However, when a window is unmapped it is also
removed from grabs and loses focus, but these state changes are not
disabled.
This change supresses the unmap side effects during the composite
unmap/map cycle and fixes this bug:
http://bugzilla.gnome.org/show_bug.cgi?id=488264
where compiz would cause gnome-screensaver to lose its grab when
compiz unredirects the fullscreen lock window.
- The (x,y)-coordinates of the crtc were not being passed as xFixed values, which made it an obscure bug to find.
- Fix bug #13787.

- This allows some compositing managers to work, even after randr12 has changed the root window size.
- Thanks to ajax for figuring out the best place to put this.
- Example:
- xf86RandR12SetMode() calls EnableDisableFBAccess().
- That calls xf86SetRootClip() which in turn calls ResizeChildrenWinSize().
- The final step is the call to PositionWindow().

In some weird cases we call this function when there is no SrvLedInfo on the
device. And it turns out null-pointer dereferences are bad.

(cherry picked from commit d954f9c803)
(first_valuator + num_valuators) must never be larger than the number of axes,
otherwise DIX freaks out. And from looking at libXI, anything larger than 6 is
wrong too.
(cherry picked from commit 9f6ae61ad1)
Move size validation after depth validation, and only validate size if
the bpp of the pixmap format is > 8. If bpp < 8 then we're already
protected from overflow by the width and height checks.

Previously, we'd just keep num_sections at 0, which would break the
geometry and lead us to leak sections. Don't do that.
(cherry picked from commit 0137b0394a)
In some cases (triggered by a key repeat during a sync grab) XKB unwrapping
can overwrite the device's realInputProc with the enqueueInputProc. When the
grab is released and the events are replayed, we end up in an infinite loop.
Each event is replayed and in replaying pushed to the end of the queue again.
This fix is a hack only. It ensures that the realInputProc is never
overwritten with the enqueueInputProc.
This fixes Bug #13511 (https://bugs.freedesktop.org/show_bug.cgi?id=13511)

If a device is already initialised (i.e. the virtual core devices) during
IASD, don't init them again. This fixes a leak.
(cherry picked from commit 1f6015c8fe62c28cfaa82cc855b5b9c28fd34607)
Initialise num_events to 1, so we always send a proximity event, and then
optionally valuator events. Also make sure mieq can deal with valuator
events sent after proximity events.

Don't run VT switches, terminations, or anything, on the core keyboard: only
run actions which affect the keyboard state. If we get an action such as VT
switch, just swallow the event.

If we got interrupted (EINTR or EAGAIN) during select, just try again, rather
than shutting clients down on either of these errors.
(cherry picked from commit b7f3618f39)
If a client disappears in the middle of CheckConnections (presumably
because its appgroup leader disappears), then don't attempt to shut it down
a second time, when it's already vanished.

Actually combine the XKB options into a string, rather than just repeatedly
writing a comma.
