    pflocal: improve the demuxer functions
    
    Handle multiple request types as recommended by the Mach Server
    Writer's Guide section 4, subsection "Handling Multiple Request
    Types".  This avoids initializing the reply message in every X_server
    function.  The reply message has already been properly initialized in
    libports, so there is no need to call mig_reply_setup.
    
    * pflocal/pflocal.c (pf_demuxer): Improve the demuxer function.
    * pflocal/sserver.c (sock_demuxer): Likewise.
