Ask and you shall receive, complete with a test case.  This patch will
try to pick up the XDG_DATA_HOME and XDG_DATA_DIRS variables and tack
on /dbus-1/services to those directories.  If not found it will use the
standards from XDG.  It even handles multiple directories separated by
colons (in XDG_DATA_DIRS only).  All of the xdg code is in
dbus-sysdeps-unix.c so that the same tag can be used under windows to
provide different standard directories there.

I want to add this patch and do a final release before 1.0 barring any
major bugs that come up.  I figure we do this release, fix up the docs
and then do a final 1.0 release if all goes well.
