We do not need two versions in the code

Windowsize was wrong when run with nxagent :<someDisplay>.

Basically three changes:
- reference sizeHints and wmHints correctly (no &)
- do not use uninitialized wmHints
- set wmHints Xutf8SetWMProperties() call instead of separate call

Events.c:2725:22: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
         message_data = validateString(NameForAtom(x.u.clientMessage.u.l.longs0));

format ‘%p’ expects argument of type ‘void *’

    [PATCH] os: XDMCP options like -query etc. should imply -listen tcp

    In X server 1.17, the default configuration is now -nolisten tcp.  In this
    configuration, XDMCP options don't work usefully, as the X server is not
    listening on the port for the display that it tells the display manager to
    connect to.

 Remove one over-zealous free() call. Thanks to Ulrich Sibiller for
 spotting this.

    Static markup and dead code cull over xkb/.

    The former <X11/extensions/XKBsrv.h> has been pulled into the server now as
    include/xkbsrv.h, and the world updated to look for it in the new place,
    since it made no sense to define server API in an extension header.  Any
    further work along this line will need to do similar things with XKBgeom.h
    and friends.

 * Support for XkbCF has been dropped in XKB extension by X.org
 * Has never been used in recent NXv3 implementations (e.g. X2Go)
 * Config file parsing is error prone, use setxkbmap API instead
