Description:
------------
With MySQL 5.5.10-log (64 bit package, downloaded from mysql.com), if the user 
does not exist when connecting to the database, the error message returned is:
Access denied for user 'rootunknown_real'@'localhost' (using password: NO)
even when a password is supplied. This breaks both mysql_connect.phpt and 
mysql_pconnect.phpt in 5.4, as they are expecting the result to be (using 
password: YES).

This also happens when running mysql from the command line, so the test should 
work around it.

If the two test cases my patch changes should be testing for YES, instead of just 
an error, then change the connect/pconnect call to use $user rather than $user .
