[pgpool-committers: 42] pgpool: Fix failover/failback in RAW mode.

[Tatsuo Ishii]

Fix failover/failback in RAW mode.
problem #1: Simply does not failover if target node is not master.
problem #2: Fail to select master node if the node is in CON_UP.
For this purpose new macro VALID_BACKEND_RAW is added, which is usefull
where health node status checking is required in raw mode.
Existing VALID_BACKEND macro does not regard standby nodes as healthy
in RAW mode.
