This avoids a build failure.

* etc/HELLO: Set 'inhibit-compacting-font-caches' non-nil
locally.  (Bug#36032)

* lisp/files.el: Add 'inhibit-compacting-font-caches' to the
list of built-in variables for which we set up
'safe-local-variable' properties.

* lisp/textmodes/page.el: Use lexical-binding.
(forward-page): Replace `(if x nil y)' with `(unless x y)'.

* test/lisp/textmodes/page-tests.el: New file with tests for page.el.

* lisp/timezone.el: Use lexical-binding.
* test/lisp/timezone-tests.el: New file.

* doc/lispref/variables.texi (File Local Variables): Document
how to define 'safe-local-variable' properties for built-in
variables.

* lisp/autoinsert.el: Use lexical-binding.
Remove redundant :group args.
(auto-insert): Simplify.

* test/lisp/autoinsert-tests.el: New file with tests for
autoinsert.el.

* nt/mingw-cfg.site (gl_cv_func_pthread_sigmask_macro): Set to
"no", to avoid compiling Gnulib's pthread_sigmask.c.
Reported by Richard Copley <rcopley@gmail.com>.

`url-insert-file-contents` saves in buffer-file-coding-system
the coding-system used to decode the contents.  Preserve this
as the contents is moved from buffer to string to buffer, and use
it when saving the contents to file, so as to try and better preserve
the original byte sequence.

(package--buffer-string, package--cs): New functions.
(package--check-signature): Encode `string` if a coding-system
was specified in buffer-file-coding-system.
(package--download-one-archive, package-install-from-archive):
Obey and preserve the buffer-file-coding-system if specified.

Do not merge.

* lisp/emacs-lisp/bytecomp.el (byte-compile-callargs-warn): Don't
assume byte-compile-fdefinition will return non-nil.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-warn-wrong-args)
(bytecomp-warn-wrong-args-subr): New tests.

Since Emacs 26, eieio objects use a class record (with circular
references) as the type descriptor of the object record.  This causes
problems when reading back an object from a string, because the class
record is not `eq' to the canonical one (which means that read objects
don't satisfy the foo-p predicate).
* lisp/emacs-lisp/eieio.el (make-instance): As a (partial) fix, set
the record's type descriptor to a plain symbol for the type descriptor
when eieio-backward-compatibility is non-nil (the default).
* lisp/emacs-lisp/eieio-core.el (eieio--object-class): Call
eieio--class-object on the type tag when eieio-backward-compatibility
is non-nil.
(eieio-object-p): Use eieio--object-class instead of
eieio--object-class-tag.
* test/lisp/emacs-lisp/eieio-tests/eieio-test-persist.el
(eieio-test-persist-hash-and-vector)
(eieio-test-persist-interior-lists): Make into functions.
(eieio-persist-hash-and-vector-backward-compatibility)
(eieio-persist-hash-and-vector-no-backward-compatibility)
(eieio-test-persist-interior-lists-backward-compatibility)
(eieio-test-persist-interior-lists-no-backward-compatibility): New
tests which call them, eieio-backward-compatibility let-bound.

* src/image.c (svg_load_image): Pacify librsvg 2.45.1 and later,
and add a FIXME comment about the deprecated librsvg functions.
Backport from master.

* src/unexelf.c (unexec): Pacify GCC 9.

* m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Remove -Wchkp.
This suppresses a boatload of warnings of the form
“gcc: warning: switch ‘-Wchkp’ is no longer supported”.
when using GCC 9.  Do not merge to master.

* src/gmalloc.c (_fraghead) [!HYBRID_MALLOC]:
Make it static in this case, too.  This avoids having both
‘extern struct list _fraghead[];’ and
‘static struct list _fraghead[BLOCKLOG];’, which
GCC 9 complains about.

* src/dbusbind.c (xd_signature): Use simpler way to set up
the subsignature.  This also pacifies GCC 9 on Fedora 30 x86-64.
Backport from master.

* src/fns.c (Fmemql, Feql): Inline to tweak performance.

* src/fns.c (Fmemql): Make `memql' work for bignums.
* test/src/fns-tests.el (test-bignum-eql): Also test `memql'.

* lisp/progmoes/cc-langs.el (c-block-comment-awkward-chars): New lang
constant and variable.

* lisp/progmodes/cc-engine.el (c-state-semi-nonlit-pos-cache): Enhance the
doc comment.
(c-state-semi-get-near-cache-entry, c-state-semi-pp-to-literal): Reuse entry
if the sought position is in a literal, and lies between the literal start and
the entry's position.
(c-cache-to-parse-ps-state, c-parse-ps-state-below): Amend such that instead
of cacheing a state for a position after a backslash or first character of a
2-character comment delimiter, this is done for the previous character
position.

* lisp/dired-aux.el (dired-do-find-regexp):
Require 'xref' (bug#35352).

* lisp/progmodes/xref.el (xref-revert-buffer): Rename from
'xref-refresh-results' (https://debbugs.gnu.org/35737#40).

* lisp/progmodes/ruby-mode.el (ruby-find-library-file):
New command.
(ruby-mode-map): Add binding for it.

* lisp/bookmark.el (bookmark-get-bookmark): Document optional
argument NOERROR. (bug#20148)

* src/xterm.h (struct x_bitmap_record) [USE_CAIRO]: Remove unused member img.

necessary.  Use x_bitmap_stipple.

Update author/maintainer info
This mostly updates email addresses and fixes spellings of
author and maintainer names.

* lisp/elec-pair.el (electric-pair-mode): Use new `depth` arg instead of
electric--sort-post-self-insertion-hook.

* lisp/emacs-lisp/syntax.el (syntax-propertize, syntax-ppss):
Use new `depth` arg to make sure noone accidentally gets added
after syntax-ppss-flush-cache.

* doc/lispref/modes.texi (Setting Hooks): Document new `depth` arg.

* test/lisp/subr-tests.el (subr-tests-add-hook-depth): New test.
