Move window resize code from window.c to window.el.

* window.c: Remove declarations of Qwindow_size_fixed,
window_min_size_1, window_min_size_2, window_min_size,
size_window, window_fixed_size_p, enlarge_window, delete_window.
Remove static from declaration of Qdelete_window, it's
temporarily needed by Fbury_buffer.
(replace_window): Don't assign orig_top_line and
orig_total_lines.
(Fdelete_window, delete_window): Remove.  Window deletion is
handled by window.el.
(window_loop): Remove DELETE_OTHER_WINDOWS case.  Replace
Fdelete_window calls with calls to Qdelete_window.
(Fdelete_other_windows): Remove.  Deleting other windows is
handled by window.el.
(window_fixed_size_p): Remove.  Fixed-sizeness of windows is
handled in window.el.
(window_min_size_2, window_min_size_1, window_min_size): Remove.
Window minimum sizes are handled in window.el.
(shrink_windows, size_window, set_window_height)
(set_window_width, change_window_heights, window_height)
(window_width, CURBEG, CURSIZE, enlarge_window)
(adjust_window_trailing_edge, Fadjust_window_trailing_edge)
(Fenlarge_window, Fshrink_window): Remove.  Window resizing is
handled in window.el.
(make_dummy_parent): Rename to make_parent_window and give it a
second argument horflag.
(make_window): Don't set resize_proportionally any more.
(Fsplit_window): Remove.  Windows are split in window.el.
(save_restore_action, save_restore_orig_size)
(shrink_window_lowest_first, save_restore_orig_size): Remove.
Resize mini windows in window.el.
(grow_mini_window, shrink_mini_window): Implement by calling
Qresize_root_window_vertically, resize_window_check and
resize_window_apply.
(saved_window, Fset_window_configuration, save_window_save): Do
not handle orig_top_line, orig_total_lines, and
resize_proportionally.
(window_min_height, window_min_width): Move to window.el.
(keys_of_window): Move bindings for delete-other-windows,
split-window, delete-window and enlarge-window to window.el.

* buffer.c: Temporarily extern Qdelete_window.
(Fbury_buffer): Temporarily call Qdelete_window instead of
Fdelete_window (Fbury_buffer will move to window.el soon).

* frame.c (set_menu_bar_lines_1): Remove code handling
orig_top_line and orig_total_lines.

* dispnew.c (adjust_frame_glyphs_initially): Don't use
set_window_height but set heights directly.
(change_frame_size_1): Use resize_frame_windows.

* xdisp.c (init_xdisp): Don't use set_window_height but set
heights directly.

* xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines): Use
resize_frame_windows instead of change_window_heights and run
run_window_configuration_change_hook.

* w32fns.c (x_set_tool_bar_lines): Use resize_frame_windows
instead of change_window_heights and run
run_window_configuration_change_hook.

* window.el (window-min-height, window-min-width): Move here
from window.c.  Add defcustoms and rewrite doc-strings.
(resize-mini-window, resize-window): New functions.
(adjust-window-trailing-edge, enlarge-window, shrink-window):
Move here from window.c.
(maximize-window, minimize-window): New functions.
(delete-window, delete-other-windows, split-window): Move here
from window.c.
(window-split-min-size): New function.
(split-window-keep-point): Mention split-window-above-each-other
instead of split-window-vertically.
(split-window-above-each-other, split-window-vertically): Rename
split-window-vertically to split-window-above-each-other and
provide defalias for old definition.
(split-window-side-by-side, split-window-horizontally): Rename
split-window-horizontally to split-window-side-by-side and provide
defalias for the old definition.
(ctl-x-map): Move bindings for delete-window,
delete-other-windows and enlarge-window here from window.c.
Replace bindings for split-window-vertically and
split-window-horizontally by bindings for
split-window-above-each-other and split-window-side-by-side.

* cus-start.el (all): Remove entries for window-min-height and
window-min-width.  Add entries for window-splits and
window-nest.
