Description:
------------
When asked to specify a server in a TCP/IP environment the name 'localhost' has always worked - it works with lots of other packages.  However it is clearly not working with the latest mysqlnd driver.  We have to specify 127.0.0.1 - which to me has always been synonymous with 'localhost'.

Can we please have the option of specifying 'localhost' back?

I understand there are technical reasons for using the IP address, but this is really hard to explain to our bosses: why the upgrade failed, why the system was down for 3 days, and specifically why this setting was changed to begin with - they just don't understand - I barely understand.

Two lines of code should do it:
if ($servername == 'localhost')
  $servername = '127.0.0.1';

PS: I know I've written php but the C code is equally short.



Test script:
---------------
mysql_connect('localhost', 'root', 'secret');
mysql_connect('127.0.0.1', 'root', 'secret');


Expected result:
----------------
To be able to specify the mysql server name as 'localhost'
