(normal-splash-screen): Add argument `concise'.

Remove unused binding `prev-buffer'. Let-bind `splash-buffer'
to the created buffer.  If `concise' is non-nil, call
`display-buffer', otherwise `switch-to-buffer'.  Doc fix.
(display-startup-screen): Add argument `concise' to the call to
`normal-splash-screen'.
