* etc/HELLO: Show off display of Hebrew with diacriticals
(a.k.a. "nikkud").

* src/w32reg.c (w32_get_string_resource): The argument V_RDB
is a 'char **', not a 'char *'.  This fixes -xrm handling on
MS-Windows, broken by conversion of x_get_string_resource to
terminal-specific hook.

(cherry picked from commit 833097cb)

* src/w32font.c (w32font_draw): Convert the glyph_string's
char2b array to 16-bit WCHAR data that ExtTextOutW needs.

(cherry picked from commit 38564f8a)

* src/w32uniscribe.c [HAVE_HARFBUZZ]: Include math.h and
hb.h.
(bswap_32): Define for GCC 4.3.0 and later; else include
<byteswap.h> from Gnulib.
(struct uniscribe_font_info): Extend for HarfBuzz; 'cache' is
now a 'void *' (all users changed).
[HAVE_HARFBUZZ]: Define typedefs for HarfBuzz functions to be
loaded dynamically from the HarfBuzz DLL.  Define macros to
call those functions via function pointers.
(uniscribe_open) [HAVE_HARFBUZZ]: Use the HarfBuzz font driver
if the type of the font entity is 'harfbuzz'.
(uniscribe_close) [HAVE_HARFBUZZ]: For fonts using the
HarfBuzz backend, call hb_font_destroy to free memory used for
the cached hb_font data.
(uniscribe_shape): Fix assignment of character codepoints to
glyphs from a single cluster.
(w32hb_list, w32hb_match, free_cb, w32hb_get_font_table)

* src/lisp.h (get_unicode_property): Declare prototype.
* src/font.h (harfbuzz_font_driver) [HAVE_NTGUI]: Declare.
* src/chartab.c (get_unicode_property): New function, body
taken from get-unicode-property-internal.
(Fget_unicode_property_internal): Call get_unicode_property
after validating input.

* doc/lispref/frames.texi (Font and Color Parameters):
* doc/emacs/msdos.texi (Windows Fonts): Document support for
HarfBuzz text shaping on MS-Windows.

* configure.ac (HAVE_HARFBUZZ): Move out of the X-specific
part, and consider HarfBuzz also for HAVE_W32 systems.
Require HarfBuzz v1.2.3 for w32.

* src/ftfont.h (ftfont_open2): Remove extern.
(ftfont_fix_match, ftfont_add_rendering_parameters)
(ftfont_entity_pattern): Add externs.
(struct font_info): Remove member bitmap_strike_index.
(struct font_info) [USE_CAIRO]: Remove member ft_size_draw.  All uses removed.

functions from here ...

assign ftcrfont_info->ft_size and call corresponding ftfont functions.

For discussion, see the following thread:
https://lists.gnu.org/archive/html/emacs-devel/2019-05/msg00500.html
* lisp/url/url-handlers.el: Update autoloaded docstrings.
Quote function symbols as such.
(url-handler-regexp): Make grouping construct shy.
(url-file-handler, url-insert-buffer-contents)
(url-handlers-create-wrapper, url-handlers-set-buffer-mode):
Simplify.
(url-file-handler-identity): Clarify calling convention.
(file-name-absolute-p, url-file-local-copy): Mark ignored arguments
as such.
(url-handler-directory-file-name): Prefer string comparison over
regexp match where either will do.
(url-copy-file): Handle integer as third argument as per copy-file.

(sgml--syntax-propertize-ppss):New variable and function.
(sgml-syntax-propertize-rules): Use it.
Don't ignore quotes not followed by a matching quote or a '>' or '<'.
(sgml-syntax-propertize): Set up sgml--syntax-propertize-ppss.

* test/lisp/textmodes/sgml-mode-tests.el (sgml-tests--quotes-syntax):
Add test for lone '>'.

This is a minor patch to remove some fixnum restrictions.
Many more such patches are needed, but one thing at a time.
* doc/emacs/custom.texi (Examining): Update fill-column example.
* src/buffer.c (fill-column, left-margin, tab-width)
(buffer-saved-size, left-margin-width, right-margin-width)
(left-fringe-width, right-fringe-width, scroll-bar-width)
(scroll-bar-height, buffer-display-count):
Allow any integer; do not restrict to fixnums.
* src/character.h (SANE_TAB_WIDTH): Do not assume tab_width
is a nonnegative fixnum.
(sanitize_tab_width): Take a Lisp_Object integer, not an
EMACS_INT.  Only use changed.
* src/data.c (store_symval_forwarding): Remove unnecessary
SYMBOLP since the predicate (e.g., Qintegerp) is always a
symbol (leave the test in as an eassert).  Avoid assignments
inside if-conditions.
* src/fileio.c (Fdo_auto_save): Do not assume
buffer-saved-size is a fixnum.  Avoid undefined behavior
on EMACS_INT overflow by multiplying a fixnum by at most 4,
not by at most 13.
* src/window.c (set_window_buffer): When buffer-display-count
is too large for a fixnum, make it a bignum.
* src/xdisp.c (FILL_COLUMN_INDICATOR_NEEDED): Remove macro, ...
(fill_column_indicator_column): ... replacing with this new function.
All uses changed.  The function is a bit pickier, to prevent
problems with non-character fixnums and columns out of range
for int, and to remove the assumption that integers are in
fixnum range.
(append_space_for_newline, extend_face_to_end_of_line):
Avoid undefined behavior with signed integer overflow.
Simplify.

Formally, when DEFUNs still used knr argument lists, these were indented by
the syntactic context knr-argdecl-intro (5 columns).  Since this is no longer

Make `auto-revert-avoid-polling' have effect in global-auto-revert-mode.
Buffers actually handled by that mode are marked with a non-nil value
of `auto-revert--global-mode'.  When global-auto-revert-mode is
entered, eligible buffers are marked in that way, and hooks are set up
to mark new buffers and take care of buffers whose file names change.
This way the existing poll-avoidance logic can be used, since the
entire set of buffers in auto-revert is known.

A new hook, `after-set-visited-file-name-hook', was added to handle
the case when the file name of a tracked buffer changes.

* lisp/autorevert.el (auto-revert-avoid-polling): Amend doc string.
(auto-revert--global-mode): New buffer-local variable.
(global-auto-revert-mode): Mark existing buffers and set up hooks when
mode is entered; do the opposite when exited.
(auto-revert--global-add-current-buffer)
(auto-revert--global-adopt-current-buffer)
(auto-revert--set-visited-file-name-advice): New functions.
(auto-revert--polled-buffers, auto-revert--need-polling-p)
(auto-revert-notify-handler)
(auto-revert-active-p): Modify logic to cover global-auto-revert-mode.
* lisp/files.el (after-set-visited-file-name-hook): New hook.
(set-visited-file-name-hook): Call new hook.
* test/lisp/autorevert-tests.el (top):  Use lexical-binding.
(auto-revert-test--write-file, auto-revert-test--buffer-string)
(auto-revert-test--wait-for, auto-revert-test--wait-for-buffer-text)
(auto-revert-test05-global-notify): New test.
* doc/lispref/hooks.texi (Standard Hooks):
Mention new hook (in a comment, since it's unclear whether it should
actually be documented here)
* etc/NEWS (Changes in Specialized Modes and Packages): Update entry.

* test/lisp/autorevert-tests.el (auto-revert--deftest-remote):
Fix typo.
(auto-revert-test02-auto-revert-deleted-file): On emba, there are
no stopped events.

Mostly, this just removes "Maintainer: emacs-devel@gnu.org" lines,
which are not that useful.  It also cleans up and regularizes a
few similar lines.

* src/keyboard.c (kbd_buffer_get_event, make_lispy_event): Use
HAVE_WINDOW_SYSTEM.

Emacs_Pix_Container is a pointer to a struct representing pixmap data
on the backend.  Emacs_Pix_Context is the context for the
bitmap/pixmap on the backend.  Only w32 currently makes this
distinction; they are otherwise the same type.

* src/dispextern.h: Remove XImagePtr in favor of
using XImage* directly. Rename XImagePtr_or_DC to Emacs_Pix_Context.
[HAVE_X_WINDOWS] Alias Emacs_Pix_Container and
Emacs_Pix_Context to XImage*.
[HAVE_NS] Alias Emacs_Pix_Container and Emacs_Pix_Context to trivial
Emacs_Pixmap definition.
[HAVE_NTGUI]: Alias Emacs_Pix_Container to XImage* and
Emacs_Pix_Context to HDC.

* src/dispextern.h:
* src/image.c: Use Emacs_Pix_Container over XImagePtr and
Emacs_Pix_Context over XImagePtr_or_DC.
