[pgpool-committers: 6952] pgpool: Refactor "show pool_nodes" command.

[Tatsuo Ishii]

Refactor "show pool_nodes" command.

Now number of codes in nodes_reporting() is dramatically reduced by
introducing send_row_description_and_data_rows(), a workhorse to
produce reports. Eventually other reporting functions will be
refactored as well.
