message:
Redesign redisplay interface to drop global variable updated_window.
Always pass currently updated window as a parameter to update routines.
* dispextern.h (updated_window): Remove declaration.
(struct redisplay_interface): Pass window parameter to
write_glyphs, insert_glyphs, clear_end_of_line, cursor_to
and after_update_window_hook.
(x_write_glyphs, x_insert_glyphs, x_clear_end_of_line, x_cursor_to):
Adjust prototypes.
* dispnew.c (updated_window): Remove.
(redraw_overlapped_rows, update_marginal_area, update_text_area)
(update_window_line): Adjust to match redisplay interface changes.
* nsterm.m (ns_update_window_begin, ns_update_window_end)
(ns_scroll_run, ns_after_update_window_line):
* w32term.c (x_update_window_begin, x_update_window_end)
(x_after_update_window_line, x_scroll_run):
* xterm.c (x_update_window_begin, x_update_window_end)
(x_after_update_window_line, x_scroll_run):
* xdisp.c (x_write_glyphs, x_insert_glyphs, x_clear_end_of_line):
Likewise. Adjust comments where appropriate.
(x_cursor_to): Simplify because this is always called during window
update (but install debugging check anyway).
(expose_window): Check must_be_updated_p flag to see whether this
function is called during window update.

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.
