Finish the security improvements:

  o Add "allow" command:
      "allow users a b c" gives access to users a, b and c.
      "allow modes auto"  gives those users access to auto mode only.
      "allow users *" and  "allow modes *" are accepted.
      No users and all modes are allowed by default.
    UID 0 can do anything.
  o Set the current label with the "load" and "dial" commands
    so that the call to ppp.linkdown makes sense.
  o Up the verison number.
  o Don't OR MODE_AUTO for -background and -ddial.
  o Don't OR MODE_INTER when we get a diagnostic connection.
  o Allow up to 40 args per line (was 20).
  o "set ifaddr" only changes the interface in AUTO mode (with other
    modes, it happens after IPCP negotiation).
  o Sort command descriptions in the man page.
  o Support -dedicated mode where we just talk ppp forever (no login etc).
