Backport from master.
* admin/admin.el (manual-html-fix-index-2): Don't bug out if the
makeinfo version doesn't include <ul>.
(cherry picked from commit e0e3f2b672)
* admin/admin.el (manual-meta-string): Only include the first
line, and move the rest...
(manual-links-string): ...to this new string.
(manual-html-fix-headers): Don't remove the '<meta name=' elements
produced by makeinfo, especially not the 'name="viewport"' one,

Reported by "Facundo Lander via RT" <webmasters-comment@gnu.org>,
see gnu.org ticket #1840138.
* admin/admin.el (manual-html-fix-index-2): Support Texinfo 6.8

pages.
* etc/refcards/Makefile (pl-refcard.dvi): If mex.fmt cannot be
found, invoke 'mex' instead of 'tex'.

Update and correct the databases.
(authors-renamed-files-alist): Add commentary explaining how to
add entries for renamed/moved files.
(authors-canonical-file-name): Clarify the semantics of the
arguments.
* admin/unidata/blocks.awk: Remove emoji overrides for codepoints with
Emoji_Presentation = No, they're no longer necessary.
* lisp/composite.el: Remove #xFE0F (VS-16) from the range handled by
`compose-gstring-for-variation-glyph' so it can be handled by

`auto-composition-emoji-eligible-codepoints'.
* admin/unidata/emoji-zwj.awk: Generate value for
`auto-composition-emoji-eligible-codepoints'. Add

we should try to use the emoji font for a codepoint.

Document num-processors.

* lib/nproc.c, lib/nproc.h, m4/nproc.m4:
New files, copied from Gnulib by admin/merge-gnulib.
* lisp/emacs-lisp/comp.el (w32-get-nproc): Remove decl.

* test/src/process-tests.el (process-num-processors): New test.
When configured --with-native-compilation, Emacs needs md5_stream.
Problem reported by Andy Moreton (Bug#50985#23).
* admin/merge-gnulib (GNULIB_MODULES): Add crypto/md5,
needed for --with-native-compilation.
(AVOIDED_MODULES): Avoid crypto/af_alg, since Emacs doesn’t
need to bother with kernel-supported cryptography algorithms.
* lib/gnulib.mk.in, m4/gnulib-comp.m4:
Regenerate by running admin/merge-gnulib.
* lib/md5-stream.c: New file, copied from Gnulib.
Make the following changes by hand, and run 'admin/merge-gnulib'.
* .gitignore: Add lib/malloc/*.gl.h.
* admin/merge-gnulib: Copy lib/af_alg.h and lib/save-cwd.h
directly from Gnulib, without worrying about Gnulib modules,
as these files are special cases.
(AVOIDED_MODULES): Remove malloc-posix.
* lib/malloc.c, lib/realloc.c, m4/malloc.m4, m4/realloc.m4:
* m4/year2038.m4: New files, copied from Gnulib.

Remove. These are either no longer present in Gnulib, or are no
longer needed by modules that Emacs uses.

needed for new Gnulib.
* src/xmenu.c: Call emacs_abort, not abort.

'x-selection-value'.
* doc/lispintro/emacs-lisp-intro.texi (Point and mark)
(Point and mark, Design @value{COUNT-WORDS}): Avoid using obsolete
name 'count-lines-region'.
* doc/lispref/hooks.texi (Standard Hooks): Remove reference to
obsolete abnormal hook 'completion-annotate-function'.
* doc/misc/efaq.texi (SPC no longer completes file names): Remove
reference to obsolete 'minibuffer-local-filename-must-match-map';
setting it has no effect.
* doc/misc/gnus.texi (NNTP): Remove reference to obsolete variable
'nntp-authinfo-file'.
* doc/misc/reftex.texi (Table of Contents, Creating Citations)
(Options - Table of Contents, Options - Referencing Labels)
(Options - Creating Citations, Options - Index Support)
(Options - Index Support, Changes): Don't use obsolete names.
* doc/misc/speedbar.texi (Minor Display Modes)
(Major Display Modes): Make variable name suggestions more in line
with existing non-obsolete variable.

obsolete variable names.
* lisp/progmodes/which-func.el (which-func-mode): Doc fix.
If the codepoint that triggered composition is from the emoji script,
use the emoji font to check the string being composed, rather than the
font of the first character of the string. This makes e.g.
"emoji codepoint with Emoji_Presentation = No followed by VS-16 (FE0F)"
display the emoji version of the glyph for that codepoint.
* admin/unidata/blocks.awk: Add VS-1 through VS-16 to the emoji
script.
* src/composite.c (autocmp_chars): Accept additional argument CH for
the codepoint that triggered composition, pass it to font_range.
(composition_reseat_it, find_automatic_composition): Pass codepoint
that triggered composition to autocmp_chars.
* src/font.c (font_range): Accept additional argument CH for the
triggering codepoint. If the codepoint is from the 'emoji' script,
use Vscript_representative_chars to find the font to use for the
composition attempt.
(syms_of_font): Add Qemoji symbol.
* src/font.h: Update font_range prototype for argument CH.
* etc/NEWS: Announce change.
Read skin tone modifier sequences from emoji-sequences.txt and add
them to the per-character composition rules derived from
emoji-zwj-sequences.txt, rather than adding them as lookback rules for
the skin tone modifiers. This avoids an issue with the application of
such lookback rules. See Bug#39799,
specifically
<https://lists.gnu.org/archive/html/bug-gnu-emacs/2021-09/msg01878.html>
for more details.
* admin/unidata/Makefile.in (zwj): Add emoji-sequences.txt as a dependency.
* admin/unidata/emoji-zwj.awk: Match RGI_Emoji_ZWJ_Sequence and
RGI_Emoji_Modifier_Sequence. Remove manual addition of skin tone
composition rules with lookback.
* lisp/textmodes/etc-authors-mode.el: New file. (Bug#50674)
* etc/AUTHORS (mode): Add "mode: etc-authors" to local variables.
* admin/authors.el (authors): Add "mode: etc-authors" to local
variables of the generated AUTHORS file.
