Drop async_visible and async_iconified fields of struct frame.

Browse source 
This is possible because async input is gone; for details, see
http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
* frame.h (struct frame): Remove async_visible and async_iconified
members, convert garbaged to unsigned bitfield.  Adjust comments.
(FRAME_SAMPLE_VISIBILITY): Remove.  Adjust all users.
(SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
* frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
* w32term.c: Ditto.
(w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
properly.  Likewise for obscured.
* xterm.c: Ditto.
(handle_one_xevent): Save visible state go generate ICONIFY_EVENT
properly.
* nsterm.m: Ditto.
(windowDidDeminiaturize): Generate DEICONIFY_EVENT.

visible frames that are actually completely obscured by other

if equal to 2, then the frame is obscured - we still consider
it to be "visible" as seen from lisp, but we don't bother
updating it. We must take care to garbage the frame when it
ceases to be obscured though.

/* Emacs's redisplay code could become confused if a frame's
visibility changes at arbitrary times. For example, if a frame is
visible while the desired glyphs are being built, but becomes
invisible before they are updated, then some rows of the
desired_glyphs will be left marked as enabled after redisplay is
complete, which should never happen. The next time the frame
becomes visible, redisplay will probably barf.
Currently, there are no similar situations involving iconified, but
the principle is the same.
So instead of having asynchronous input handlers directly set and
clear the frame's visibility and iconification flags, they just set
the async_visible and async_iconified flags; the redisplay code
calls the FRAME_SAMPLE_VISIBILITY macro before doing any redisplay,
which sets visible and iconified from their asynchronous
counterparts.
Synchronous code must use the FRAME_SET_VISIBLE macro.
Also, if a frame used to be invisible, but has just become visible,
it must be marked as garbaged, since redisplay hasn't been keeping
up its contents.
Note that a tty frame is visible if and only if it is the topmost
frame. */
