Per https://wiki.php.net/rfc/mysql_deprecation, connecting to a MySQL database
via ext/mysql now generates an E_DEPRECATED error. This commit includes the
minimal EXPECTF updates required for the test suite to pass: it may be
preferable to refactor some of the tests to suppress deprecation errors in
situations where no other error is expected from mysql_[p]connect(), but I'm
not enough of a MySQL expert to want to get my hands that dirty in a long
standing test suite.
MYSQL_TEST_SKIP_CONNECT_FAILURE which controls how to deal with connection
problems. If MYSQL_TEST_SKIP_CONNECT_FAILURE = false (default) connection
problems will make a test fail. If you set MYSQL_TEST_SKIP_CONNECT_FAILURE
to any value that evaluates to true in PHP, a test which cannot connect to
the database will be skipped.
