So what (IMO) should be done is when --enable-dso is specified:

- move dso modules to
  and then move SVN_VER_XYZ to configure.in


  move version from build.conf to configure.in, pass it to
  load_ra_module() and place all dso modules - libxyz-${version}.so
  - in $(libdir}/subversion/ (I prefer this)

- use -module

- rename modules to xyz.so or libxyz.so

- remove versioning (-avoid-version) to get libxyz.so instead
  of libxyz.so.0.0.0

Something else? +1 for that?

Load all *.so from $(libdir}/subversion/ ?
