[Pgpool-committers] pgpool - pgpool-II: Fix bug with healh checking.

[User T-ishii]

Log Message:
-----------
Fix bug with healh checking. If a network problem such as unplugged
wire happens while calling connect(), health checking does not work
since connect_unix_domain_socket()/connect_inet_domain_socket() do
retry if connect() is interrupted by ALARM signal. Added new retry
argument which controls the retrying behavior to those functions.
Per bug report and problem analysis by Daniel Codina.
See following message for more details.
