patch 8.1.2265: when popup with "botleft" does not fit it flips incorrectlyv8.1.2265

Problem:    When popup with "botleft" does not fit it flips incorrectly.
Solution:   Only flip when there is more space on the other side.  Add the
            "posinvert" option to disable flipping and do it in both
            directions if enabled.  (closes #5151)
