Uses _NET_WM_NAME to get UTF-8 encoding, iconv to convert to current locale
Warns that COMPOUND_TEXT WM_NAMEs aren't supported if _NET_WM_NAME isn't set
Adds local atom caching code to dsimple.c and uses it in all three *.c

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%
Memory size when exit() is called:
Xlib:
Address Kbytes RSS Anon Locked Mode Mapped File
08043000 20 20 20 - rw--- [ stack ]
08400000 144 144 144 - rw--- [ heap ]

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.

This also uses XORG_CHANGELOG and XORG_CWARNFLAGS, corrects
make distcheck and most gcc 4.3 and sparse warnings.

This should fix things in WM’s using virtual roots as well as in tabbing WM’s.
