[pgpool-committers: 2398] pgpool: Tighten up checking for app_name_redirect_preference_list and d

[Tatsuo Ishii]

Tighten up checking for app_name_redirect_preference_list and database_redirect_preference_list.

Before empty application name or database name and invalid DB node
number (like "foo1bar") were silently accepted. Now they are strictly
checked and let raise fatal error when starting up. Problem reported
in [pgpool-general-jp: 1337].
