moved definition of the various socket paths from the
per daemon header files into configure.ac. it will set the paths to
be in the directory specified by --localstatedir=<prefix> or
otherwise will try to guess as best it can ( a la pid file path
detection - which probably should try reference ${prefix} too).
the present hardcoded socket path, /tmp, isnt really correct. should
be in /var somewhere really.
