patch 8.0.0761: options not set properly for a terminal buffer

Problem:    Options of a buffer for a terminal window are not set properly.
Solution:   Add "terminal" value for 'buftype'.  Make 'buftype' and
            'bufhidden' not depend on the quickfix feature.
            Also set the buffer name and show "running" or "finished" in the
            window title.
