DRILL-3894: Upgrade functions MaxDir, MinDir... Optional filename parameter - added implementations
of functions MAXDIR, IMAXDIR, MINDIR, IMINDIR with one (schema) without filename argument;
- added UTest for results comparison of using Query Directory Functions with one and two arguments.

This closes #467
