mod_dav_svn from subversion 1.7.x does not build against apache 2.4

Since the API in Apache 2.4.x has changed the mod_dav_svn module from svn doesn’t build currently. I made patch for that. There is only a small issue in subversion/mod_dav_svn/util.c

                           errscan->desc, errscan->status, errscan->error_id);
         }

Now it compiles against Apache 2.2 and Apache 2.4

Any feedback is welcome.
