[pgpool-committers: 8434] pgpool: Implement comma separated multiple listen addresses.

[Tatsuo Ishii]

Implement comma separated multiple listen addresses.

Pgpool-II only allowed to set single hostname, IP or '*' to the
listen_addresses parameter. Now we can set multiple listen addresses
to the parameter as PostgreSQL already does.  Note that the
documentations for listen_addresses are shamelessly stolen from
PostgreSQL.
