Description of Problem:

RFE: Provide support for mod_auth_mysql to connect to a MySQL database running
on any port. 

mod_auth_mysql uses mysql_connect() to connect to the db. This function
according to the MySQL documentation is deprecated and does not allow the
selection of a port number.

Version-Release number of selected component (if applicable):

1.11 included with 7.3, applies to new versions as well.

How Reproducible:

always

Steps to Reproduce:
1. Install 
2. Configure Apache to use
3. notice that there is no way to specify a port number.

Actual Results:

must have mysql running on port 3306 to use

Expected Results:

There is no reason why one shouldn't be able to run mysqld on any port they want
and still use this module.

Additional Information

Patch included :)

Adds 1 optional parameter to the module:

AuthMySQLPort 3306  # port number option, defaults to 3306 if not specified.
