Freeing resources during client closedown can cause cursor changes which
attempt to send cursor events through the XFixes extension; a client in the
process of closing down has no file to send events to, causing a crash when
this path is hit.
Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
