exec: improve the exec_demuxer function
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. Furthermore, move the exec_startup_server_routine to the end of the chain, as the startup related functions are only needed at system bootstrap time. * exec/main.c (exec_demuxer): Improve the demuxer function.
