Description of problem:
php mysqli does not properly support SSL options

Version-Release number of selected component (if applicable):
5.3.2-6.el6_0.1.x86_64

How reproducible:
always

Reproduce code:
---------------
<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);
$mysqli = mysqli_init();
$mysqli->ssl_set('./cert/client-key.pem', './cert/client-cert.pem', './cert/mysql-cacert.pem', null, null);
$mysqli->real_connect('removed', '', '', '');
if ($r = $mysqli->query("SHOW STATUS LIKE 'Ssl_cipher'")) {
    var_dump($r->fetch_row());
}
echo $mysqli->error."\n";
echo $mysqli->errno."\n";
?>

Actual result:
--------------
Warning: mysqli::ssl_set(): invalid object or resource mysqli

with MYSQLI_CLIENT_SSL
Can't connect to MySQL server on 'removed' (113)
errno = 2003
 
without MYSQLI_CLIENT_SSL
Warning: mysqli::real_connect(): (28000/1045): Access denied for 
user 'removed' (using password: YES)
errno = 1045

ssl_set() in this case returns NULL, not true as doc says.

Expected result:
----------------
something like this for Ssl_cipher
array(2) {
  [0]=>
  string(10) "Ssl_cipher"
  [1]=>
  string(18) "DHE-RSA-AES256-SHA"
}

and no errors.
