(1) Provide new option 'x-gtk-resize-child-frames' which allows
to either hide a child frame during resizing or asks GTK to
resize it "immediately". This is needed because desktops like
GNOME shell otherwise won't allow resizing child frames at all.
(2) Do not try to synchronize the position of a child frame
after moving it. Needed because the present implementation
introduces a 0.5 secs delay which makes dragging child frames
virtually impossible with Lucid and Motif toolkits on desktops
like GNOME shell that use invisible outer frame borders.

* src/frame.c (syms_of_frame): New symbol Qxg_frame_set_char_size_4.
* src/gtkutil.c (xg_frame_set_char_size): Hide child frame
during resizing when 'x-gtk-resize-child-frames' equals 'hide'.
* src/xfns.c (x_set_parent_frame, Fx_create_frame): Set
gtk_container_resize_mode to GTK_RESIZE_IMMEDIATE for child
frames when'x-gtk-resize-child-frames' equals 'resize-mode'.
(Fx_gtk_debug): New function to toggle interactive GTK debugging
from within Emacs.
(syms_of_xfns): New symbols Qhide and Qresize_mode.
(x-gtk-resize-child-frames): New option that allows to resize
child frames on desktops like GNOME shell (with the mutter WM)
that otherwise refuse to resize them.
* src/xterm.c (x_set_offset): Don't x_sync_with_move for child
frames, it makes moving child frames virtually impossible with
the Lucid and Motif toolkits.

44ac9e48bb Tweak htmlfontify's generated output
Optimise for the common case of encoding or decoding an ASCII-only
string using an ASCII-compatible coding, for file names in particular.
* src/coding.c (string_ascii_p): New function.
(code_convert_string): Return the input string for ASCII-only inputs
and ASCII-compatible codings.
* test/src/coding-tests.el (coding-nocopy-ascii): New test.
In {encode,decode}-coding-string, the NOCOPY parameter had the
opposite effect to what was intended and documented. This 18 year old
bug (introduced in 4031e2bf0a) only affected calls with CODING-SYSTEM
being nil.
* src/coding.c (code_convert_string): Correct use of NOCOPY.
* test/src/coding-tests.el (coding-nocopy-trivial): New test.
* src/bignum.c (check_integer_range, check_uinteger_max)
(check_int_nonnegative): New functions.
* src/frame.c (check_frame_pixels): New function.
(Fset_frame_height, Fset_frame_width, Fset_frame_size): Use it.
* src/lisp.h (CHECK_RANGED_INTEGER, CHECK_TYPE_RANGED_INTEGER):
Remove these macros. Unless otherwise specified, all callers
replaced by calls to check_integer_range, check_uinteger_range,
check_int_nonnegative.
* src/frame.c (gui_set_right_divider_width)
(gui_set_bottom_divider_width):
* src/nsfns.m (ns_set_internal_border_width):
* src/xfns.c (x_set_internal_border_width):
Using check_int_nonnegative means these functions no longer
incorrectly reject negative bignums; they treat them as 0,
just like negative fixnums.
* doc/man/emacs.1.in: Fix syntax of --script argument. The Info
manual states that --script has to be followed by a space, and the
syntax with the equals sign doesn't actually work.
Completely rewrite the code that displayes the summaries, so all
backends share the same code.
(archive--summarize-descs): New function.
(archive-arc-summarize, archive-lzh-summarize, archive-zip-summarize)
(archive-zoo-summarize, archive-rar-summarize, archive-7z-summarize)
(archive-ar-summarize): Use it.

(archive-file-name-coding-system, archive-files): Use `defvar-local`.
(archive-extract): Use `setq-local`.
(archive-get-descr): Use `user-error` when clicking on a directory.
* src/character.c (Fstring, Funibyte_string):
Redo to avoid the need for a temporary array allocation
and then a copying from that array to the destination.
* lisp/vc/log-edit.el (log-edit-fill-entry): Relax regexp a bit to
recognize function entries with leading blanks.
* test/lisp/vc/log-edit-tests.el: New test.
Add fields `size`, `time` (used by all backends) as well as
`pos`, `ratio`, `uid`, and `gid` (used only be some backends).
(archive-arc--file-desc, archive-rar--file-desc, archive-ar--file-desc)
(archive-lzh--file-desc, archive-zip--file-desc, archive-7z--file-desc):
Remove defstructs.
(archive-arc-summarize): Record size and time in the descrs.
(archive-lzh-summarize): Record size, time, uid, and gid in the descrs.
(archive-zip-summarize): Record size and time in the descrs.
(archive-zoo-summarize): Record size and time in the descrs.
(archive-rar-summarize): Adjust to use of `archive--file-desc`.

* lisp/emacs-lisp/re-builder.el (reb-while): Take the current value of
the counter instead of its name.
(reb-mark-non-matching-parenthesis): Bind n-reb to 0 at the start and
don't wrongly treat it as dynamicly bound.
Problem reported by Martin Rudalics in:
https://lists.gnu.org/r/emacs-devel/2020-04/msg00195.html
* configure.ac (DEFINE_KEY_OPS_AS_MACROS): Define if -Og.
* src/Makefile.in (KEY_OPS_CFLAGS): New macro.
(EMACS_CFLAGS): Use it.
* src/lisp.h (DEFINE_KEY_OPS_AS_MACROS): Let the gcc command line
specify it. Remove use of undocumented INLINING macro.
* lisp/progmodes/gdb-mi.el (gdb-control-commands-regexp): Add
support for "explore", "explore value", and "explore type".
Allow more than one word after control commands.
(gdb-gdb): Decrease gdb-control-level when we get the "(gdb)"
prompt, which signals that "explore" exited. (Bug#40250)
* lisp/faces.el (face-spec-choose): Reverse order of 'defaults'
and 'result' when generating attribute list, so that the spec for
'default' "terminal class" is indeed overridden by the actual
class's spec, per the documentation. (Bug#40336)
(archive--file-desc): Remove `case-fiddled`.
Change all subtypes's constructors as their callers accordingly.
(archive--file-desc-case-fiddled): New function.
(archive-int-to-mode): Accept a nil input.
Make all callers take advantage of it.
(archive-arc-rename-entry): Use `make-string`.
(archive-zip--file-desc): Change `pos+len` field into `pos` field.
(archive-zip-chmod-entry): Simplify accordingly.
(archive-zip-summarize): Don't bother with `lheader` which was not used.
(archive-zoo--file-desc): Delete struct; use archive--file-desc instead.
(archive-7z--file-desc): Remove `user` and `group` fields.
Adjust constructor and its caller.
(archive-ar-summarize): Use `archive-int-to-mode`.
* lisp/progmodes/cc-engine.el (c-looking-at-or-maybe-in-bracelist): Add code
to recognize a literal brace expression following an array declaration for
C++.
(c-looking-at-inexpr-block): Replace c-symbol-chars with c-symbol-char-key,
fixing a coding error.
* src/emacs-module.c (module_copy_string_contents): Fix incorrect
variable use. In this branch 'lisp_str_utf8' is always nil, so it
makes little sense to add it as error data.
In i386 ABI parameter passing of structs (and unions) is done as
pointer + size. Surprisingly this is done *always* even if the
structure is known to be word size.
(archive-ar--name): New funtion, extracted from `archive-ar-summarize`.
(archive-ar-extract): Use it.
(archive-ar-summarize): Use it. Put the extname in the slot 0 of the
desc vectors.
(arc-insert-unibyte): Simplify.
(archive--mode-revert): Rename from `archive-mode-revert` and adjust
for use as an :around advice.
(archive-mode): Use setq-local. Use `add-function` to hook into
`revert-buffer-function`.
(archive-summarize): Don't use `set` on a hook.
* lisp/net/dns.el (dns-set-servers): Set dns-servers to nil when we
don't find any DNS servers with nslookup. Add support for IPv6
servers. (Bug#40248).
(dns-make-network-process): Check for datagram process support before
creating a datagram process.
(dns-query): Return nil if dns-servers is nil.
The handling of :coding nil was different between
make-{network,serial}-process and make-{pipe}process. Now they all
handle :coding nil as if :coding had not been specified.
* process.c (Fmake_serial_process)
(set_network_socket_coding_system): Use plist-get to check if
:coding has been specified instead of plist-member, to ensure that
":coding nil" does not override coding-system-for-{read,write}.
* network-stream-tests.el (check-network-process-coding-system-bind)
(check-network-process-coding-system-no-override)
(check-network-process-coding-system-override): New tests.
* etc/NEWS: Describe change in make-network-process and
make-serial-process :coding behavior.
* lisp/textmodes/texinfo.el (texinfo-texi2dvi-options): New
defcustom.
(texinfo-tex-buffer): Take 'tex-start-options' from
'texinfo-texi2dvi-options'. (Bug#40001)
* etc/NEWS: Mention the new option.
Copyright-paperwork-exempt: yes
* lisp/epg-config.el (epg-config--make-gpg-configuration): Bind
coding-system-for-read/write to 'undecided', to countermand
possible values of 'no-conversion' or somesuch by the callers.
(Bug#40248)
