[pgpool-committers: 8685] pgpool: Rename configuration parameter delegate_IP to delegate_ip.

[Bo Peng]

Rename configuration parameter delegate_IP to delegate_ip.

For compatibility with the old versions, the old paramter delegate_IP can still work.
If the old paramter delegate_IP is used, Pgpool-II will set the value to
delegate_ip and throw a warning message.

This commit also fixes segfault of fail_over_on_backend_error
and changes the behavior to set the value to failover_on_backend_error
if fail_over_on_backend_error is used.
