Remove a few simple cases of global redisplay

Remove a few simple cases of global redisplay

* src/dispnew.c (redraw_frame): Don't redisplay all frames.

* src/xdisp.c (echo_area_display): Set the frame's `redisplay' bit
rather than returning a "resized_p" boolean.
(redisplay_internal): Adjust call accordingly.

* src/xfaces.c (free_realized_faces): Don't redisplay all frames.
(free_all_realized_faces): Set windows_or_buffers_changed so as to ease
tracking of this undesirable situation.
