[PULL] Fix Damage protocol for Xinerama

[Adam Jackson]

Same as the v5 series I sent a bit ago.  2 and 3 aren't reviewed yet,
though 2 is at least trivial.  Tested against the nvidia driver and
against a hacked Xvfb, both root and toplevel reports appear to be sane
now, and Subtracts are clipped to the (logical) root window.

Sadly this does not result in, say, 'xcompmgr -n' drawing what you'd
expect.  This appears to be due to bugs outside the Damage extension
proper, which I'm still looking into, but at least the protocol is
closer to correct.  (xcompmgr -a _does_ work, but that's not entirely
surprising, the cm doesn't actually do any work in that case and no
Damage protocol is ever generated.)
