squid_db_auth to support md5 encrypted passwords patch

[Milen Pankov <mail@xxxxxxxxxxxxxxx>]

Hi,

Recently I needed to use squid_db_auth against mysql database with md5
encrypted passwords.

I read a recent discussion on this list (Joomla DB authentication
support hits Squid!:)) that was regarding integration with joomla
database, but this wasn't working for me.

Here's a patch that makes it possible to read md5 encrypted passwords
from the database with the --md5 option.
