o Kill shell_noargs option, it cannot work since the command needs to
  be set before sudoers is parsed.
o Fix the "set_home" sudoers option (only worked at compile time).
o Fix "fqdn" sudoers option.  We now set host/shost via set_fqdn which
  gets called when the "fqdn" option is set in sudoers.
o Move the openlog() to store_syslogfac() so this gets overridden
  correctly from the sudoers file.
