Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.

Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.
Omit ‘#include "foo.h"’ unless the file needs foo.h (Bug#21707).
In a few cases, add ‘#include "foo.h"’ if the file needs foo.h
but does not include it directly. As a general rule, a source
file should include foo.h if it needs the interfaces that foo.h
defines.

dependency on libXt-devel.
* src/menu.h [HAVE_NTGUI]: Include lwlib-widget.h in this case too.

lwlib-widget.h now does this.

Avoid unnecessary 'const', typically the second 'const' in
'const foo * const arg', a 'const' that does not affect the API
and doesn't significantly help the human reader.
Wnen XEvent is processed, it is unlikely to be changed except
KeyPress case, so we can avoid copying and use const pointer to
const data to make sure that an event is not changed elsewhere.
* xterm.c (handle_one_xevent): Change 2nd arg to 'const XEvent *
const' and do not create local copy except for the KeyPress event.

* xterm.h, gtkutil.h, xsettngs.h: Adjust related prototypes.
This change streamlines the window system selection code in
configure.in and moves many common function declarations from
window-specific headers to frame.h. It introduces a new TERM_HEADER
macro in config.h: we set this macro to the right header to use for
the window system for which we're compiling Emacs and have source
files include it indirectly. This way, we don't have to teach every
file about every window system.
* gtkutil.c (xg_get_font): Rename from xg_get_font_name. When
using the new font chooser, use gtk_font_chooser_get_font_desc to
extract the font descriptor instead of just the font name. In
that case, return a font spec instead of a string.
(x_last_font_name): Move to this file from xfns.c.
* xfns.c (Fx_select_font): The return value can also be a font
spec. Move x_last_font_name management to gtkutil.c.
