v7: Don't bother making resources for the backing listeners. [keithp]
This is now slightly unlike how other resources are xineramified. We
create N+1 internal damage listeners, one that's a real resource and
reflects the protocol view, and then one per backend screen where the
report function piles onto the protocol view. The internal listeners
are not stored in the resource database directly, they just hang off the
xinerama resource. We don't wrap Subtract at the dispatch level, but we
do extend it for the Xinerama case to clip to the root window geometry.
As a result of the N+1 design here, the damage reports we generate are
not quite minimal. However they are indistinguishable from sequential
rendering events happening before the client hears damage, and we don't
need to add a post-dispatch callback just for this one extension.
Add is probably (still) somewhat broken since it will only hit screen 0,
but Add really only exists for DRI1's sake, and DRI1 disables itself
with Xinerama enabled anyway. In the absence of a use case, I'm leaving
it unwrapped under Xinerama; if someone wants to define how it ought to
work, be my guest.

at -100+0 in the coordinate space of the right hand screen. Put another
way: windows are in the coordinate space of their root window pixmap.
We weren't doing this translation for the COW, so when rendering came in
to it you'd see the top-left chunk of the COW on all screens. Cool
effect and all, but wrong.

A default timeslice of 20ms means a pathological client can ruin up to
two frames per scheduler tick. And a fifth of a second is just insane.
Pick two different numbers out of the hat. A 5ms slice means you can
probably keep up with two or three abusive clients, and letting it burst
to 15ms should give you about all the timeslice you need for a
fullscreen game (that's doing server-side rendering for some reason).
If you're running on a system with a 10ms granularity on SIGALRM, then
this effectively changes the intervals to 10ms and 30ms. Which is still
better, just not as better.
I suspect this is about as good as we can do without actually going
preemptive, which is an entire other nightmare.
