Do not reset window modification event counters excessively.

These leftovers and poor man's tricky methods to catch extra
redisplay's attention are no longer needed.
* frame.c (set_menu_bar_lines_1):
* minibuf.c (read_minibuf_unwind):
* window.c (Fset_window_start, set_window_buffer, window_resize_apply)
(grow_mini_window, shrink_mini_window, window_scroll_pixel_based)
(window_scroll_line_based, Fset_window_configuration):
* xdisp.c (redisplay_window): Do not reset last_modified and
last_overlay_modified counters.
