xf86SetSingleMode tries to resize all crtcs to match the selected mode. When
a CRTC has no matching mode, it now disables the CRTC (instead of crashing).
Also, poke the RandR extension when xf86SetSingleMode is done so that
appropriate events can be delivered, and so that future RandR queries return
correct information.

/sys/devices reflects the bus topology, and we don't care that much.
Easier (and more reliable) to just look in /sys/bus/pci/devices, which
is a flat view.
When we see an evdev or vmmouse section, assume that it's a mouse, and
don't add a default mouse device. This will break users who have an
evdev keyboard section but no mouse, and want the mouse to get added
by default.
Now, fbcmap_mi.c contains the fb functions which just wrap mi functions.
Previously, these were in fbcmap.c and compiled when XFree86Server was defined.
Now, clients of fbcmap should either use fbcmap.c or fbcmap_mi.c and not worry
about setting the XFree86Server symbol.
Erasing this variable causes some outputs (SDVO on intel) to fail
to be correctly reset at server reset time.

It seems that the changes to X input exposed a problem that wasn't detected
before. The axis clipping code in GetPointerEvents() uses those limits to
constrain the pointer's coordinate range. The max was zero so the pointer
couldn't move.
Use new dmxCoreMotion2() function which enqueues motion events with
GetPointerEvents()/mieqEnqueue().
The clipAxis() code in GetPointerEvents() is causing some grief. The
limits seem to have always been (0,0) according to the original calls
to InitValuatorAxisStruct() in dmxinputinit.c.
Terrible hack for now: Call InitValuatorAxisStruct() with hard-coded max
values of 1280 (my screen width).
Additionally, protect libcw setup behind checks for Render, to avoid
segfaulting if Render isn't available (xnest).
The previous setup was an ABI-preserving dance, which is better nuked now.
Now, anything that needs libcw must explicitly initialize it, and
miDisableCompositeWrapper (previously only called by EXA and presumably binary
drivers) is gone.
