Use argp_ functions instead of getopt to parse command

line arguments. This allows all mailutils programs
to share common code and to have the same subset
of command line options. Besides, this allows to have
a single configuration file for entire package.
The common command-line subsets are (struct argp_child):

  1. mu_common_argp_child: handles --maildir,--log-facility,
     --license and --sql-.* family of options. (The latter
     are used to supply data for SQL getpwnam et al. functions
     instead of hard-coding them).
  2. mu_daemon_argp_child: handles --daemon,--inetd,--port
     and --timeout options.
