Major rewrite of adjust_frame_size

Have adjust_frame_size pass native frame sizes to backends
instead of text sizes.  Expand frame size history management.
Drop PIXELWISE argument from change_frame_size and convert
native to text sizes only when calling adjust_frame_size.  Use
convention in arguments that -1 instead of 0 means that no size
change is required.  When adjusting frame sizes pick up delayed
size changes (Bug#46827).

* lisp/frame.el (frame-notice-user-settings, make-frame): Don't
set frame size history.
(frame--size-history): Rewrite doc-string.  Handle new formats
of `frame-size-history' entries.
* src/dispextern.h (delayed_size_change): Extern it.
(change_frame_size): Drop last argument from extern.
* src/dispnew.c (delayed_size_change): Make it global.
(handle_window_change_signal): Reformat.  Drop last argument
from change_frame_size call.
(do_pending_window_change, init_display_interactive): Drop last
argument from change_frame_size call.
(change_frame_size_1): NEW_WIDTH and NEW_HEIGHT now specify
native sizes.  Drop last argument PIXELWISE.  Queue a change
when it either differs from F's current pixel sizes or F's
previously queued sizes.  Inject frame_size_history_extra call
when queuing.  Adopt convention that for queued sizes -1 means
that no size change is required.  Convert from native to text
sizes when calling adjust_frame_size.
(change_frame_size): Drop last argument PIXELWISE and drop it
also in change_frame_size_1 calls.
* src/frame.c (frame_size_history_add): Remove.
(frame_inhibit_resize): Remove call to frame_size_history_add.
(set_menu_bar_lines, set_tab_bar_lines): Simplify.  Drop last
argument from change_frame_size call.
(frame_windows_min_size): No more static.
(keep_ratio): Minor rewrite using macros.
(frame_size_history_adjust, frame_size_history_plain)
(frame_size_history_extra): New functions.
(adjust_frame_size): Major rewrite.  Adopt new convention that
negative values for new sizes mean no change.  Pick up delayed
size changes from F's new_width and new_height slots
(Bug#46827).  Call set_window_size_hook with native instead of
text sizes.  Do not sanitize window sizes any more.  Call
frame_size_history_adjust instead of frame_size_history_add.
Always set F's resized_p slot to true.
(make_frame): Initialize new_width and new_height slots to -1.
Simplify setup of initial sizes and an adjust_frame_size call.
(Fframe_parameters): Drop processing F's new_pixelwise slot.
(check_frame_pixels): Reorder to make declarations appear first.
(Fset_frame_height, Fset_frame_width, Fset_frame_size): Pass
explicit width and height values to adjust_frame_size instead of
-1.
(gui_set_frame_parameters): Minor rewrite making sure that
explicit sizes and the corresponding parameter are passed to
adjust_frame_size.  Remove frame_size_history_add call.
(gui_figure_window_size): Drop last two arguments.  Simplify
assignment of initial size.  Set new_height and new_width slots
to -1.  Use adjust_frame_size to set sizes instead of returning
them to caller.
(syms_of_frame): Drop symbols used by frame size history; these
are now built on-the-fly.  Also drop some menu bar related
symbols in favor of Qmenu_bar_lines.
* src/frame.h (struct frame): Remove new_pixelwise.
(SET_FRAME_COLS, SET_FRAME_LINES, SET_FRAME_WIDTH)
(SET_FRAME_HEIGHT): Remove macros.
(frame_size_history_add): Remove externs.
(frame_windows_min_size, frame_size_history_plain)
(frame_size_history_extra): Add externs.
(FRAME_WINDOWS_WIDTH, FRAME_WINDOWS_HEIGHT): Rename to
FRAME_INNER_WIDTH and FRAME_INNER_HEIGHT.
(gui_figure_window_size): Drop last two arguments from
extern.
* src/gtkutil.c (xg_frame_resized): Rename arguments to WIDTH
and HEIGHT.  Consult delayed_size_change to handle case where
WIDTH and HEIGHT do not match F's new_width and new_height
values.  Call change_frame_size with native sizes and without
PIXELWISE argument.  Instead of frame_size_history_add call
frame_size_history_extra.
(xg_frame_set_char_size): WIDTH and HEIGHT are native sizes now;
fix adjust_frame_size call accordingly.  Instead of
frame_size_history_add call frame_size_history_extra.
(style_changed_cb): Call xg_frame_set_char_size with native
instead of text sizes.
(tb_size_cb): Remove frame_size_history_add call.  Call
adjust_frame_size with INHIBIT 5.
(free_frame_tool_bar, xg_change_toolbar_position): Remove
frame_size_history_add call.
(update_frame_tool_bar): Call adjust_frame_size with INHIBIT 2
and let it handle frame_inhibit_implied_resize and
fullheight/-width.  Remove frame_size_history_add call.
* src/keyboard.c (Fsuspend_emacs): Call change_frame_size with
native sizes.
* src/nsfns.m (ns_set_tool_bar_lines): Call adjust_frame_size
with INHIBIT 2 and let it handle frame_inhibit_implied_resize
and fullheight/-width.  Remove frame_size_history_add call.
(Fx_create_frame): Drop two last arguments in
gui_figure_window_size call.  Do not SET_FRAME_WIDTH and
SET_FRAME_HEIGHT, the adjust_frame_size in
gui_figure_window_size did that already.
* src/nsterm.m (ns_set_window_size): Drop PIXELWISE argument and
its processing; WIDTH and HEIGHT represent native pixel sizes
now.  Call change_frame_size with native sizes.  Remove call to
frame_size_history_add.
([EmacsView viewDidResize:]): Call change_frame_size with native
sizes.
* src/term.c (Fresume_tty): Call change_frame_size with native
sizes.
* src/termhooks.h (*set_window_size_hook): Drop last argument
PIXELWISE.
* src/w32fns.c (w32_change_tab_bar_height)
(w32_change_tool_bar_height): Fix handling of these in the initial
phase before they have been resized at least once.
(Fx_create_frame, w32_create_tip_frame): Drop two last arguments
in gui_figure_window_size call.  Do not SET_FRAME_WIDTH and
SET_FRAME_HEIGHT (or SET_FRAME_COLS and SET_FRAME_LINES), the
adjust_frame_size in gui_figure_window_size did that already.
* src/w32inevt.c (resize_event, maybe_generate_resize_event):
Pass native sizes to change_frame_size.
* src/w32term.c (w32_read_socket): When WM_WINDOWPOSCHANGED pass
native sizes to change_frame_size.

code.

(w32_set_window_size): Drop argument PIXELWISE and its
processing; WIDTH and HEIGHT are native sizes now.  Remove
frame_size_history_add calls.  Pass native sizes to
change_frame_size.
* src/widget.c (set_frame_size): Set width and height of widget
directly.  Call frame_size_history_plain instead of
frame_size_history_add.
(update_from_various_frame_slots): Call
frame_size_history_extra.
(EmacsFrameRealize): Call frame_size_history_plain.
(EmacsFrameResize): Call change_frame_size with native sizes.
Call frame_size_history_extra instead of frame_size_history_add.
(EmacsFrameSetCharSize): Call frame_size_history_extra.  Drop

not redisplay it.
(redisplay_tool_bar): Don't call it for external tool bar.
Don't set tool_bar_redisplayed when we did not redisplay it.
(redisplay_window): When the tool bar is external call
update_frame_tool_bar directly.
* src/xfns.c (x_set_menu_bar_lines): Call adjust_frame_size only
if number of menu bar lines changed and fix 6th argument.
(x_change_tab_bar_height, x_change_tool_bar_height): Fix
handling of these in the initial phase before they have been
resized at least once.
(Fx_create_frame, x_create_tip_frame): Drop two last arguments
in gui_figure_window_size call.  Do not SET_FRAME_WIDTH and
SET_FRAME_HEIGHT (or SET_FRAME_COLS and SET_FRAME_LINES), the
adjust_frame_size in gui_figure_window_size did that already.
* src/xmenu.c (update_frame_menubar): Fix 6th arg of
adjust_frame_size call.
(free_frame_menubar): For Motif frames fix fullscreen and
`frame-inhibit-implied-resize' handling.  Fix 6th arg of
adjust_frame_size calls.
* src/xterm.c (x_net_wm_state): Remove call to
frame_size_history_add.
(handle_one_xevent): For PropertyNotify and UnmapNotify events
add frame_size_history_plain calls.  For MapNotify and

some frame_size_history_add calls and add frame_size_history_extra
calls instead.  If the frame is not visible call adjust_frame_size
directly instead of calling change_frame_size.
(x_set_window_size): Drop PIXELWISE argument.  WIDTH and HEIGHT
represent native sizes now.
