Remember the version the client sent to us, so we can adjust our replies
accordingly. This requires the client to use the {major|minor}Version fields
in the GetExtensionVersion request. However, they were padding before, so we
must assume they are garbage if nbytes is non-zero. If nbytes is zero, the
client is probably a new client and we can handle it correctly.
Move SendEventToAllWindows and FindInterestedChildren from chgptr to exevents,
so the DIX can more easily use it.
Clean up two warnings (type mismatch, unused variable) in exevents.c.
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>.
