[PATCH] dmx: Construct paths in doxygen.conf to fix VPATH builds

[Dan Nicholson]

The paths in doxygen.conf assumed that srcdir=builddir and broke
otherwise. Use autoconf to fill in the paths to the srcdir so that the
files can be found when users have a separate build directory (as with
distcheck).

 I actually tested this now and contains a fix where the Makefile was
 referencing $(srcdir)/doxygen.conf, but it's now being created in the
 build directory.

 I also have rename detection on here to make the reviewing easier, so
 you'll need git am or apply to do the right thing.
