[pgpool-committers: 2327] pgpool: Reorganize port numbers assigned in pgool_setup.

[Tatsuo Ishii]

Reorganize port numbers assigned in pgool_setup.

Assign base port (11000 by default) to pgpool, base port + 1 to pcp,
port + 2 to PostgreSQL node0, port + 3 to PostgreSQL node1 and so on.
This assigns fixed port numbers to pgpool and pcp port, which makes
pgpool_setup user's life a little bit easier, because they don't need
to check README.port to make sure the pgpool and pcp port any more.

Some of regression tests uses immediate numeric port numbers and
adjusted to meet the change.
