This also allow to configure with --without-xmlto to ignore
a 3rd party xmlto tool on systems that normally don't have it,
in order to have reproducable builds.
Problem reported by kili@. Patch with help from Gaetan Nadon
(memsize at videotron dot ca) on X.Org devel list.

Fix segv for clipped movie window
When playing a movie that is clipped on its left and right edges the
Xorg server will SEGV sometimes. This is because the intel driver
ignores the clipping info when it copies the planes out of the XV
data. The check for the optimised copy was wrong to ignore the
width required. Which leads to too much data being copied by the
memcpy. It the source buffe happens to end exactly on a page
boundary the server will SEGV.
As we reviewed the code we checked the calculation of src1, src2 and
src3. The patch includes additional comments to make it clear what
the elements of the calculation are.
This bug exists in git head and we also see it in 2.4.1.
it works kinda like _CWM_GRP, which we added to aid restarts a while
ago, but it's standardised and clients are specifically allowed to set
it to request a desktop.
for noe we leave _CWM_GRP support in, but its days are now numbered.
while i'm here fixup an int/long mixup with an earlier diff.

says that a pager can change the property at any time (most need a
clientmessage). So deal with property updates.
Needed to shuffle some of the other code around since we can't just use
shortcut_to_name[] everywhere now.
ok okan@
remove screen_current() it was utterly bogus when nscreens > 1.
pass a fake client_ctx in the case where there's no client and the
kbfunc or mousefunc doesn't need a real one, it just contains the
current screen, modify these functions so that they pass down the screen
context to their callees.
make groups per screen, it's the only way it makes sense in this regard.
ok okan@.
