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.
This patch just changes code files; a followup companion patch
(much larger) will affect the commentary. This part is
separated out to make it easier to review.

(org-info-map-html-url):
* lisp/org/ox-html.el (org-html-creator-string):
* lisp/startup.el (fancy-startup-text, fancy-about-text)
(fancy-splash-head):
* test/lisp/ffap-tests.el (ffap-other-window--bug-25352):
* test/lisp/thingatpt-tests.el (thing-at-point-test-data):
Use HTTPS instead of HTTP.
* lisp/color.el (color-name-to-rgb, color-complement): Clarify in
docstrings that RGB triplets should use four digits per component.
(color-rgb-to-hsl): Break line to avoid "Hidden behind deeper element"
warning.
* test/lisp/color-tests.el: New file.
* lisp/url/url-gw.el (url-open-stream): Only use :nowait if
we're doing async connections (bug#26835).
* lisp/url/url-parse.el (url): Add an asynchronous slot.
* lisp/url/url.el (url-asynchronous): New variable.
(url-retrieve-internal): Store the value.
(url-retrieve-synchronously): Bind the variable.
* test/lisp/net/tramp-tests.el (seq): Don't require.
(tramp--test-emacs26-p): New defun.
(tramp-test10-write-region, tramp-test11-copy-file)
(tramp-test12-rename-file, tramp-test15-copy-directory)
(tramp-test21-file-links): Use it.
(tramp-test16-file-expand-wildcards): Use `copy-sequence'.
Also make its behaviour consistent with and-let* in that empty bindings
results in success, not failure.
* lisp/emacs-lisp/subr-x.el: Edit docstring, change else to then.
'cl-gensym' was simply moved here, but let us take an opportunity to
shed some historical baggage.
* lisp/subr.el (gensym): Remove special treatment of PREFIX as a
number. Use "g" as prefix to differentiate from cl-gensym defaults.
* doc/lispref/symbols.texi (Creating Symbols): Update accordingly.
* lisp/emacs-lisp/cl-macs.el (cl--gensym-counter, cl-gensym): Restore.
configure.ac: Add boilerplate for configuring and detecting liblcms2.
etc/NEWS: Mention new configure option and color-distance change.
src/Makefile.in: Add references to lcms.c and liblcms.
src/emacs.c: Define lcms2 symbols.
src/lcms.c: New file.
src/lisp.h: Add declaration for lcms2.
src/xfaces.c: Add optional METRIC argument.
Removing extraneous code, thanks to Michael Heerdegen.
* lisp/emacs-lisp/subr-x.el (internal--listify): Remove latter
condition which always evaluates to t.
(internal--build-binding-value-form): Remove dead code.
Bug#28412
* lisp/files.el (basic-save-buffer): Re-arrange function so that
write-contents-functions are run earlier. If they return non-nil,
consider the buffer saved without requiring the buffer to be
visiting a file.
(save-some-buffers): This function should consider any buffer with a
buffer-local value for write-contents-functions eligible for
saving.
* test/lisp/files-tests.el (files-test-no-file-write-contents): New
test.
* doc/lispref/files.texi (Saving Buffers): Mention in docs.
* etc/NEWS: And in NEWS.
* Makefile.in (${srcdir}/info/dir): Tweak shell command so
that an ordinary make says just "GEN info/dir" rather than
also having a seemingly-unrelated mv line.
This also includes changes to if-let and when-let. The single tuple
special case is ambiguous, and binding a symbol to nil is not as
useful as binding it to its value outside the lexical scope of the
binding. (Bug#28254)
* etc/NEWS: Mention.
* lisp/emacs-lisp/subr-x.el (internal--listify):
(internal--build-binding-value-form): Extend to account for
solitary symbols and (EXPR) items in binding varlist.
(if-let*, when-let*): Nix single tuple case and incumbent
bind-symbol-to-nil behavior.
(and-let*): New macro.
(if-let, when-let): Mark obsolete. Redefine in terms of if-let*, so
they implicitly gain the new features without breaking existing code.
* test/lisp/emacs-lisp/subr-x-tests.el: Adjust tests for: lack of
single-tuple special case, lack of binding solitary symbols to nil,
and the introduction of uninterned symbols for (EXPR) bindings. Add
SRFI-2 test suite adapted to Elisp.
The security patches released for Emacs 25.3 were less drastic
than what we had immediately put into master. Adjust master to
match 25.3 (Bug#28350).
* lisp/textmodes/enriched.el (enriched-translations):
Re-enable FUNCTION and display translations that are safe.
(enriched-handle-display-prop): Bring back.
(enriched-decode-display-prop): Bring back, but disable
the unsafe part.
* lisp/progmodes/cc-engine.el (c-restore-<>-properties): After failing an
attempted match from the start of a token (in particular, "<<"), move to the
next token rather than the nex character before searching for the next "<".
This printing, while succint, is rather opaque. At least give an
immediate clue of whether different byte code printouts are for the
same or different byte code objects.
* lisp/emacs-lisp/cl-print.el (cl-print-object): Add object sxhash to
printed token "#<bytecode>".
* etc/NEWS: Mention this.
* lisp/thumbs.el (thumbs-rename-images): Treat the destination
as special only if it is a directory name. When there is
a marked list, turn the destination into a directory name
if it is not already.
Change write-file to be consistent with the new behavior
of copy-file, etc.
* etc/NEWS: Mention this.
* lisp/files.el (write-file): Treat the destination as special
only if it is a directory name.
Do the special dance with the destination only if it is a
directory name, for consistency with copy-file etc. (Bug#27986).
* doc/emacs/files.texi (Copying and Naming):
* doc/lispref/files.texi (Create/Delete Dirs):
* etc/NEWS: Document this.
* lisp/files.el (copy-directory): Treat NEWNAME as special
only if it is a directory name.
* lisp/files.el (files--ensure-directory): New function.
(make-directory): Use it to avoid bugs when (make-directory FOO t)
is invoked on a non-directory, or on a directory hierarchy that
is being built by some other process while Emacs is running.
* test/lisp/files-tests.el (files-tests--make-directory): New test.
