This patch restores most of Ryan's patch (11/12/2001) to remove the

client_socket from the conn_rec.  Diffs from Ryan's patch include:

- rename the create_connection hook to install_transport_filters
- move the point of invocation of the hook till after the call to
  after ap_update_vhost_given_ip to enable the hook to use vhost
  config info in its decision making.
