(cherry picked from commit 37f4e7651a)
Despite all the careful planning of the kernel, a link may become
insufficient to handle the currently-set mode. At this point, the
kernel should mark this particular configuration as being broken
and potentially prune the mode before setting the offending connector's
link-status to BAD and send the userspace a hotplug event. This may
happen right after a modeset or later on.
Upon receiving a hot-plug event, we iterate through the connectors to
re-apply the currently-set mode on all the connectors that have a
link-status property set to BAD. The kernel may be able to get the
link to work by dropping to using a lower link bpp (with the same
display bpp). However, the modeset may fail if the kernel has pruned
the mode, so to make users aware of this problem a warning is outputed
in the logs to warn about having a potentially-black display.
This patch does not modify the current behaviour of always propagating
the events to the randr clients. This allows desktop environments to
re-probe the connectors and select a new resolution based on the new
(currated) mode list if a mode disapeared. This behaviour is expected in
order to pass the Display Port compliance tests.

In the typical pattern in games of "hide cursor, grab with a confineTo,
warp constantly the pointer to the middle of the window" the last warping
step is actually rather optional. Some games may choose to just set up a
grab with confineTo argument, and trust that they'll get correct relative
X/Y axis values despite the hidden cursor hitting the confinement window
edge.
To cater for these cases, lock the pointer whenever there is a pointer
confinement and the cursor is hidden. This ensures the pointer position
is in sync with the compositor's when it's next shown again, and more
importantly resorts to the relative pointer for event delivery.

Previously, we would swap the width/height of the Xwayland output based
on the output rotation, so that the overall screen size would match the
actual rotation of each output.
Problem is the RandR's ConstrainCursorHarder() handler will also apply
the output rotation, meaning that when the output is rotated, the
pointer will be constrained within the wrong dimension.
Moreover, XRandR assumes the original output width/height are unchanged
when the output is rotated, so by changing the Xwayland output width and
height based on rotation, Xwayland causes XRandr to report the wrong
output sizes (an output of size 1024x768 rotated left or right should
remain 1024x768, not 768x1024).
So to avoid this issue and keep things consistent between Wayland and
Xwayland outputs, leave the actual width/height unchanged but apply the
rotation when computing the screen size. This fixes both the output size
being wrong in "xrandr -q" and the pointer being constrained in the
wrong dimension with rotated with weston.

In InitOutput, if xf86HandleConfigFile returns CONFIG_NOFILE

xf86AutoConfig calls xf86OutputClassDriverList via the
call tree:
xf86AutoConfig =>
listPossibleVideoDrivers =>
xf86PlatformMatchDriver =>
xf86OutputClassDriverList
and xf86OutputClassDriverList attempts to traverse a linked list
that is a member of the XF86ConfigRec struct pointed to by the
global xf86configptr, which is NULL at this point because the
XF86ConfigRec struct is only allocated (by xf86readConfigFile)
AFTER the config file and directory have been successfully
opened; the CONFIG_NOFILE return from xf86HandleConfigFile
occurs BEFORE the call to xf86readConfigFile which allocates
the XF86ConfigRec struct.
Rx: In read.c (for symmetry with xf86freeConfig, which already
appears in this file), add a new function xf86allocateConfig
which tests the value of xf86configptr and, if it's NULL,
allocates the XF86ConfigRec struct and deposits the pointer

Sometimes, Xwayland will try to use a cursor that has just been freed,
leading to a crash when trying to access that cursor data either in
miPointerUpdateSprite() or AnimCurTimerNotify().
CheckMotion() updates the pointer's cursor based on which xwindow
XYToWindow() returns, and Xwayland implements its own xwl_xy_to_window()
to fake a crossing to the root window when the pointer has left the
Wayland surface but is still within the xwindow.
But after an xwindow is unrealized, the last xwindow used to match the
xwindows is cleared so two consecutive calls to xwl_xy_to_window() may
not return the same xwindow.
To avoid this issue, update the last_xwindow based on enter and leave
notifications instead of xwl_xy_to_window(), and check if the xwindow
found by the regular miXYToWindow() is a child of the known last
xwindow, so that multiple consecutive calls to xwl_xy_to_window()
return the same xwindow, being either the one found by miXYToWindow()
or the root window.

wl_keyboard::leave needs to be handled in the same way as its

This patch uses LeaveNotify for these events on wl_keyboard::leave and

touch device, which appears to be NULL. Reason being the device itself
is more a keyboard device than a touch device.
Moreover, it appears the device is neither enabled nor activated
(inited=0, enabled=0) which doesn't seem right, but matches the code in
init_touch() from xwayland-input.c which would enable the device if it
was previously existing and otherwise would create the device but not
activate it.
Make sure we do activate and enable touch devices just like we do for
other input devices such as keyboard and pointer.

Prior to this commit the Xorg.wrap code to detect if root rights are
necessary checked for DRM_IOCTL_MODE_GETRESOURCES succeeding *and*
reporting more then 0 output connectors.
DRM_IOCTL_MODE_GETRESOURCES succeeding alone is enough to differentiate
between old drm only cards (which need ums and thus root) and kms capable
cards.
Some hybrid gfx laptops have 0 output connectors on one of their 2 GPUs,
resulting in Xorg needlessly running as root. This commits removes the
res.count_connectors > 0 check, fixing this.
