  Prevent resetting of NATted realtime peer address on reload.

  If a "sip reload" is issued for a SIP peer, then his
  IP address will be cleared, thus resulting in forgetting the
  public IP address. Asterisk will then attempt to route SIP
  traffic to the private IP address.

  The fix here is to make "sip reload" ignore realtime peers
  when "host = dynamic" is spotted. Realtime peers can now only
  have their IP address reset if they have gone from being not
  dynamic to being dynamic.
