bgpd: Remove AS Path limit/TTL functionality

* draft-ietf-idr-as-pathlimit doesn't seem to have gone anywhere, and its
  author does not think it will make progress in IDR. Remove all support
  introduced for it, but leave stubs for the commands to avoid breaking
  any configurations.

  Basically reverts cecab5e9725792e60a5e4b473e238a14cd85815d.

-This command configures a route to be originated into BGP, just as with the
-previous command, but additionally sets an AS-Pathlimit TTL to be advertised
-on the route. See draft-ietf-idr-as-pathlimit.
-
-Specifying a TTL of 0 can be used to remove pathlimit from a previously
-configured network statement.
-
-Note that when advertising prefixes with AS-Pathlimit set, all less-specific
-prefixes advertised SHOULD also have the Atomic-Aggregate attribute set.
-Failure to do so increases the risks of accidental routing loops occuring.
-
-This implementation will try to automatically set Atomic-Aggregate as
-appropriate on any less-specific prefixes originated by the same speaker,
-however it will not (and often can not) do so where @b{other} speakers in
-the AS are originating more specifics.
-
-Hence the system administrator must take care to ensure that all
-less-specific prefixes originated carry atomic-aggregate as appropriate, by
-manually configuring speakers originating less-specifics to set
-Atomic-Aggregate on those advertisements!
