[pgpool-committers: 5450] pgpool: Fix unwanted recovery timeout in certain cases.

[Tatsuo Ishii]

Fix unwanted recovery timeout in certain cases.

In the second stage of online recovery in replication mode, it is
possible it fails with timeout (message: "wait_connection_closed:
existing connections did not close in %d sec.") if connection counter
is malformed by a child process aborts with SIGKILL, SEGFAULT or etc.
This could be detected by checking if client_idle_limit_in_recovery is
enabled and it has less value than recovery_timeout because all
clients must be kicked out by the time when
client_idle_limit_in_recovery is expired. If so, we should reset
conn_counter to 0 also.

Per bug 431.
