[RFC] porting Xephyr to xcb

[Julien Cristau]

Hi,

I've been trying to port Xephyr to xcb instead of Xlib, with an eye to
getting that upstream for 1.10, so would appreciate some eyes on it :)

I've split up the change in several commits (using libX11-xcb in the
intermediate ones) so I could test changes independently, but I'm happy
to squash it all together if people think it'd be better.

I've tested Xv, but not DRI1/GLX since I don't have such a setup
anymore.

The removal of the unused proxy stuff is independent so could be merged
separately.

The transformation is mostly straightforward.  One note though: Xephyr
used XCheckTypedWindowEvent to bundle expose event processing; I don't
know how to do that with xcb, so it's removed.

The following changes since commit a2c13f0d6548310e3cd115cf486d3e43edf23dcc:

  Bump to version 1.8.99.905 (1.9 RC5) (2010-07-14 12:57:29 -0700)
