The Connection class used the wrapper function when it could simply call
mysql_real_connect directly. This removes the unconditional error message
that would be printed even when a connection failure was expected.
For whatever reason, galera complains on startup about
wsrep_cluster_address missing even when mysql_install_db is run. By making
sure that we configure it before we initialize the database, the problems
seem to go away.
This is needed by tests that use add_test_executable_ex and require
backend SSL. Also fixed a problem in disable_ssl where an empty query was
executed instead of the query itself.
The system test information array now has the full path to the MaxScale
configuration file. The array now only contains labels given in
CMakeLists.txt. The resulting .cc-file has linebreaks for readability.
The library is now named "maxtest". The related include-files are, for
now, usable without designating the full include path. This may be changed
later, but would require modifying every test.
