    Make iconv() usage optional
    
    Allows building without iconv, though character set conversion will not
    be supported in that case.
    
    Handles UTF8_STRING validation and output for UTF-8 locales without iconv
    (using is_valid_utf8() function copied from X.Org's app/xprop/xprop.c)

    Handle non-latin-1 window names
    
    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

    Make xcb-icccm dependency be optional and off-by-default
    
    Changes to the xcb-icccm API/ABI are under discussion, so for now default
    to using local property handling code modeled after the current API, with
    a --with-xcb-icccm to enable use of the API for testing/development.
    
    Once the API/ABI is stable & released, this set of changes should be
    removed and the xcb-icccm API just used directly.

commit 96f19bade9ce4940642d580f4c52e2bc0e3539ab

    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%
    
    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 ]
    total Kb    8972    8640     316       -
    
    xcb:

    08045000      12      12      12       - rwx--    [ stack ]
    0806C000     100     100     100       - rwx--    [ heap ]
    total Kb    7980    7692     288       -
    
    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.
