49ec57d509 dix: free default colormap before screen deletion
If we don't free this here, it gets freed later in the resource
cleanups, however it then looks up up pmap->pScreen, which we
freed already in this function. So free the default colormap
when we should.

This fixes a bug after a couple of hotplug cycles when you try
to exit the X server and it crashes.

bafbd99080 dix: work around scaling issues during WarpPointer (#53037)
In WarpPointer calls, we get input in screen coordinates. They must be
scaled to device coordinates, and then back to screen coordinates for screen
crossing and root coordinates in events.

The rounding errors introduced (and clipping in core/XI 1.x events) can lead
to the actual position being different to the requested input coordinates.
e.g. 200 scales to 199.9999, truncated to 199 in the event.

Avoid this by simply overwriting the scaled screen coordinates with the
input coordinates for the POINTER_SCREEN case.

cb306a8f17 dix: make sure the mask is set for emulated scroll events (#52508)
If a device has smooth scrolling axes, but submits scroll button events, we
convert those to motion events and update the valuators. For legacy button
events, the valuator mask is likely unset though, causing
add_to_scroll_valuator() to return early, leaving us with an empty mask.
That again skipped the rest of the code and no events were generated.

Fix it by making sure that the scroll valuator in the mask is at least
initialized to 0.

Broke evdev wheel emulation, introduced by
54476b5e44.

34cf559bcf ProcGetPointerMapping uses rep.nElts before it is initialized
In:

	commit d792ac125a
	Author: Alan Coopersmith <alan.coopersmith@oracle.com>
	Date:   Mon Jul 9 19:12:43 2012 -0700

	    Use C99 designated initializers in dix Replies

the initializer for the .length element of the xGetPointerMappingReply
structure uses the value of rep.nElts, but that won't be set until
after this initializer runs, so we get garbage in the length element
and clients using it will generally wedge.

Easy to verify:

	$ xmodmap -pp

Fixed by creating a local nElts variable and using that.

f2da2c1204 randr: add initial scanout pixmap support (v3)
When randr notices a crtc configuration request for a slave device,
it checks if the slave allocated pixmap exists and is suitable,
if not it allocates a new shared pixmap from the master, shares
it to the slave, and starts the master tracking damage to it,
to keep it updated from the current front pixmap.

If the resize means the crtc is no longer used it will destroy
the slave pixmap.

This adds the concept of a scanout_pixmap to the randr_crtc object,
and also adds a master pixmap pointer to the pixmap object, along
with defining some pixmap helper functions for getting pixmap box/regions.

v2: split out pixmap sharing to a separate function.

9d457f9c55 Add screen-specific privates.
Screen-specific privates areas are only allocated for objects related
to the target screen; objects allocated for other screens will not
have the private space reserved. This saves memory in these objects
while also allowing hot-plug screens to have additional private
allocation space beyond what the core screens are using.

Drivers are encouraged to switch to this mechanism as it will reduce
memory usage in multi-GPU environments, but it is only required for
drivers which will be loaded after the server starts, like
modesetting.

Objects providing screen-specific privates *must* be managed by the
screen-specific private API when allocating or initializing privates
so that the per-screen area can be initialized properly.

The objects which support screen-specific privates are:

	Windows
	Pixmaps
	GCs
	Pictures

Extending this list to include Colormaps would be possible, but
require slightly more work as the default colormap is created before
all colormap privates are allocated during server startup, and hence
gets a bunch of special treatment.

Of particular note, glyphs are *not* capable of supporting
screen-specific privates as they are global objects, not allocated on
a screen-specific basis, and so each driver must be able to see their
privates within the glyph.

4c68f5d395 dix: disable all devices before shutdown
f3410b97cf introduced a regression on server
shutdown. If any button or key was held on shutdown (ctrl, alt, backspace
are usually still down) sending a raw event will segfault the server. The
the root windows are set to NULL before calling CloseDownDevices().

Avoid this by disabling all devices first when shutting down. Disabled
devices won't send events anymore.

Master keyboards must be disabled first, otherwise disabling the pointer
will trigger DisableDevice(keyboard) and the keyboard is removed from the
inputInfo.devices list and moved to inputInfo.off_devices. A regular loop
through inputInfo.devices would thus jump to off_devices and not recover.
