[pgpool-committers: 5626] pgpool: Fix md5 auth broken in raw mode.

[Tatsuo Ishii]

Fix md5 auth broken in raw mode.

In raw mode, pool_passwd is not necessary to authenticate PostgreSQL
using md5 auth.  However if there's more than 1 backend,
authenticating with md5 fails.

Fix is, checking whether we are operating in raw mode while do md5
authentication. This was broken in 4.0, so back-patched to only 4.0.

Per bug 491.
