[pgpool-committers: 4272] pgpool: Add debugging aid to check pending message and backend response

[Tatsuo Ishii]

Add debugging aid to check pending message and backend response.

New function pool_check_pending_message_and_reply() added.  If pending
message kind and backend reply message kind is not inconsistent, it
prints a debug message. Currently the only client of the function is
read_kind_from_backend().
