daa6d2d58f config/udev: distinguish between real keyboards and other key devices
This patch introduces a new flag ATTR_KEY for hotplugged input devices,
so we can better distinguish between real keyboards (i.e. devices with
udev property ID_INPUT_KEYBOARD="1") and other key input devices like
lid switches, power buttons, etc.

All supported hotplug backends (udev, hal, and wscons) will set both
flags ATTR_KEY and ATTR_KEYBOARD for real keyboards, but udev backend
will set ATTR_KEY, but not ATTR_KEYBOARD, for non-keyboard key input
devices (hal and wscons will set both flags in any case). With this
distinction, kdrive input hotplugging mechanism will be allowed to only
grab real keyboards, as other key input devices are currently not
supported.

In order to don't break current behaviour, this patch will replace all
ATTR_KEYBOARD occurrences with ATTR_KEY in hw/xfree86/common/xf86Xinput.c.

[ajax: Just add ATTR_KEY, don't re-number the other attributes]

f175cf45ae vidmode: move to a separate library of its own
XVidMode extension might be useful to non hardware servers as well (e.g.
Xwayand) so that applications that rely on it (e.g. lot of older games)
can at least have read access to XVidMode.

But the implementation is very XFree86 centric, so the idea is to add
a bunch of vfunc that other non-XFree86 servers can hook up into to
provide a similar functionality.

e957a2e5dd dix: Add hybrid full-size/empty-clip mode to SetRootClip
216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.

Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.

Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.

This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work
correctly, but keep the clip emptied so exposures are never generated.

fc4fbe8224 xfree86: add NoMatchFoo directives for InputClass sections
InputClass sections use various MatchFoo directives to decide which device to
apply to. This usually works fine for specific snippets but has drawbacks for
snippets that apply more generally to a multitude of devices.

This patch adds a NoMatchFoo directive to negate a match, thus allowing
snippets that only apply if a given condition is not set. Specifically, this
allows for more flexible fallback driver matching, it is now possible to use a
snippet that says "assign driver foo, but only if driver bar wasn't already
assigned to it". For example:

Section "InputClass"
   Identifier "libinput for tablets"
   MatchIsTablet "true"
   NoMatchDriver "wacom"
   Driver "libinput"
EndSection

The above only assigns libinput to tablet devices if wacom isn't already
assigned to this device, making it possible to select a specific driver by
installing/uninstalling it.

d206c240c0 configurable maximum number of clients
Make the maximum number of clients user configurable, either from the command
line or from xorg.conf

This patch works by using the MAXCLIENTS (raised to 512) as the maximum
allowed number of clients, but allowing the actual limit to be set by the
user to a lower value (keeping the default of 256).

There is a limit size of 29 bits to be used to store both the client ID and
the X resources ID, so by reducing the number of clients allowed to connect to
the X server, the user can increase the number of X resources per client or
vice-versa.

Parts of this patch are based on a similar patch from Adam Jackson

4c2f2cb4c8 dix: Add unaccelerated valuators to the ValuatorMask
Allows a mask to carry both accelerated and unaccelerated motion at the same
time.

This is required for xf86-input-libinput where the pointer acceleration
happens in libinput already, but parts of the server, specifically raw events
and DGA rely on device-specific unaccelerated data.

To ease integration add this as a second set to the ValuatorMask rather than
extending all APIs to carry a second, possibly NULL set of valuators.

Note that a valuator mask should only be used in either accel/unaccel or
standard mode at any time. Switching requires either a valuator_mask_zero()
call or unsetting all valuators one-by-one. Trying to mix the two will produce
a warning.

The server has a shortcut for changing a mask with the
valuator_mask_drop_unaccelerated() call. This saves us from having to loop
through all valuators on every event, we can just drop the bits we know we
don't want.

against the xf86_platform_device passed in.  However, it just returns
immediately without checking the rest of the entities first.  This leads to this
situation happening:

1. The nvidia driver creates an entity 0 with bus.type == BUS_PCI
2. The intel driver creates entity 1 for its platform device, opening
   /dev/dri/card0
3. xf86platformProbeDev calls probeSingleDevice on the Intel platform device,
   which calls doPlatformProbe, which calls xf86_check_platform_slot.
4. xf86_check_platform_slot compares the Intel platform device against the
   NVIDIA PCI entity.  Since they don't have the same device ID, it returns
   TRUE.
5. doPlatformProbe calls xf86ClaimPlatformSlot, which creates a duplicate entity
   for the Intel one.

Fix this by only returning FALSE if the PCI ID matches, and continuing the loop
otherwise.  In the scenario above, this allows it to continue on to find the
Intel platform device that matches the second entity.
