default values for environment variables, based on the
executable's own location.

MAX_PATH.
(sys_socket): Install socket inheritance bug fix from 20.7.
(easy-menu-do-define): Use `menu-item' format.
Handle case where easy-menu-create-menu returns a symbol.
Manually call the potential top-level filter in the function binding.
(easy-menu-filter-return): New arg NAME.
Convert to a keymap if MENU is an XEmacs menu.
(easy-menu-convert-item-1): New. Extracted from easy-menu-do-add-item.
(easy-menu-converted-items-table, easy-menu-convert-item): New.
(easy-menu-do-add-item): Use it.
(easy-menu-create-menu): Use easy-menu-convert-item.
Wrap easy-menu-filter-return around any :filter specification.
Don't convert the menu if a filter was specified.
Tell easy-menu-make-symbol not to check for MENU being an expression.
(easy-menu-make-symbol): New arg NOEXP.
(x_produce_image_glyph, x_append_stretch_glyph): Accomodate to
changes in struct glyph starting 1999-12-27. Some bit-fields of
struct glyph were not set, which made glyphs unequal when compared
with GLYPH_EQUAL_P. Redisplay outputs such glyphs, and flickering
effects were the result. This also depended on the contents of
memory returned by xmalloc. If flickering happens again, activate
the code in clear_glyph_row that's in #if 0. If the flickering is
gone with that, chances are that it is caused by something
similar.
(window_list): Order list so that, for each frame, windows are
in canonical order, and so that frames appear in the list in
the order given by Vframe_list.
(next_window): Reverse the handling of NEXT_P.

(decode_next_window_args, next_window): New functions.
(Fnext_window, Fprevious_window): Rewritten in terms of
next_window.
(Fwindow_list): New function.
(Fother_window): Cleaned up.
(foreach_window): Add a longer "variable argument list". Let
callback function return 0 to indicate that cycling over windows
should stop.
(foreach_window_1): Likewise.
(freeze_window_start): Return int.
(init_window): New function.
