Convert from Xlib to xcb
Testing was done with a simple GNOME 2.28 session with a number of
applications open (gnome-terminal, VirtualBox, Firefox).
Primary test case was xwininfo -root -all, which listed 114 children of
the root window. Output was identical to Xlib version (after applying
the fix to libxcb_icccm for always null-terminating wm_class properties).
Over a local connection on the same machine:
Xlib: 0.00u 0.01s 0:00.05 20.0%
xcb: 0.00u 0.00s 0:00.02 0.0%
(i.e. barely measurable difference - I had more variation between
repeated runs of the command)
Introducing latency by running over ssh -X from California to Beijing
and back:
Xlib: 0.03u 0.02s 8:19.12 0.0%
xcb: 0.00u 0.00s 0:45.26 0.0%

Bytes sent & received (counted by proxying via xscope):
Xlib: Client --> Server: 21380 bytes Client <-- Server: 54124 bytes
xcb: Client --> Server: 21114 bytes Client <-- Server: 53160 bytes
(The Xlib code didn't save any replies, so re-requested a couple of things
when running with -all - I fixed that while porting to xcb, but the same
could be done with Xlib easily too.)
Not yet handled: WM_NAME properties that need to be converted from another
character encoding.
