Description: If libmysql is compiled with WITH_SSL=NO,
             --ssl-* are not useful.

Solution: 1. Restricted WITH_SSL to values : bundled | yes | system
          2. Made "bundled" as default value for WITH_SSL. Also,
             not specifying WITH_SSL or even specifying WITH_SSL=no
             will be treated as/converted to WITH_SSL=bundled.
