* src/fileio.c (restore_window_points): Reverse commit
974192413f and instead replace a < by a <=.
This ensures that if w->mpoint is at the top of the middle region being
replaced, it gets adjusted and stays at the top after the reinsertion.
* src/xwidget.c (run_file_chooser_cb): New function that runs
a nested event loop instead of acting asynchronously.
(Fmake_xwidget): Attach file chooser signal.
This is no longer required, as we rely on X to position
xwidgets now. It also makes resizing Emacs frames slightly
slower.
* src/emacsgtkfixed.c (EMACS_FIXED_GET_CLASS)
(struct GtkFixedPrivateL)
(emacs_fixed_gtk_widget_size_allocate)
(emacs_fixed_class_init) [HAVE_XWIDGETS]: Remove unused code.
This fixes bug #51776.
* src/fileio.c (restore_window_points): Restore a w->mpoint even when that
marker originally pointed into the unchanged area near BOB or EOB. This
prevents that window's point being moved a long way from its starting place
due to the removal of the central part of the buffer by insert_file_contents.
* src/coding.c (Fdecode_coding_region): Doc fix.
* doc/lispref/nonascii.texi (Coding System Basics)
(Explicit Encoding): Explain the significance of using 'undecided'
in 'decode-coding-*' functions.
The comment probably dated back to when xwidgets supported
many other GTK+ widgets with other data. In the current
implementation of xwidgets, everything that should be freed
is already freed in `kill_buffer_xwidgets'.
* src/xwidget.c (kill_buffer_xwidgets): Remove outdated TODO.

This is done in preparation for the introduction of other
xwidgets, such as media xwidgets, even though there are
only WebKit widgets at present.
* src/xwidget.c (CHECK_WEBKIT_XWIDGET): New macro.
(WEBKIT_FN_INIT): Use CHECK_WEBKIT_XWIDGET.
(Fxwidget_webkit_search, Fxwidget_webkit_next_result)
(Fxwidget_webkit_previous_result)
(Fxwidget_webkit_finish_search)
(Fxwidget_webkit_load_html): Check that xwidget is a WebKit
widget.
* doc/lispref/display.texi (Xwidgets): Explain meaning of killed
xwidgets.
* src/xwidget.c (Fxwidget_live_p): New function.
(Fxwidget_perform_lispy_event, WEBKIT_FN_INIT)
(Fxwidget_resize, Fxwidget_size_request)
(Fxwidget_info, Fxwidget_plist)
(Fset_xwidget_buffer, Fset_xwidget_plist)
(Fset_xwidget_query_on_exit_flag)
(Fxwidget_query_on_exit_flag)
(Fxwidget_webkit_search)
(Fxwidget_webkit_next_result)
(Fxwidget_webkit_previous_result)
(Fxwidget_webkit_finish_search)
(Fxwidget_webkit_load_html): Check for live xwidgets instead of
just xwidgets.
(xwidget_button, xwidget_motion_or_crossing)
(xv_do_draw, x_draw_xwidget_glyph_string)
(Fdelete_xwidget_view): Ignore killed xwidgets.
(syms_of_xwidget): Define new symbols and subrs and define
appropriate weakness of id_to_xwidget map.
(kill_buffer_xwidgets): Check live xwidgets instead of
killed xwidgets, set xwidget buffer to nil, and rely on GC to
free the hash table for us instead.
* src/xwidget.h (XWIDGET_LIVE_P, CHECK_LIVE_XWIDGET): New
macros.
posix_spawn is less error-prone than vfork + execve, and can make
better use of system-specific enhancements like 'clone' on Linux. Use
it if we don't need to configure a pseudoterminal.
* configure.ac (HAVE_SPAWN_H, HAVE_POSIX_SPAWN)
(HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR)
(HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR_NP)
(HAVE_POSIX_SPAWNATTR_SETFLAGS, HAVE_DECL_POSIX_SPAWN_SETSID): New
configuration variables.
* src/callproc.c (USABLE_POSIX_SPAWN): New configuration macro.
(emacs_posix_spawn_init_actions)
(emacs_posix_spawn_init_attributes, emacs_posix_spawn_init): New
helper functions.
(emacs_spawn): Use posix_spawn if possible.
* src/term.c (init_tty): Fix the change which introduced support
for the terminfo Tc flag. The code as installed broke colors in
PuTTY -nw sessions, because 'tigetflag' returned -1, which is
non-zero, so it was treated as the sign that true color is
supported. But if the value returned by 'tigetflag' is -1, it means
the capability is not a boolean one, so that's not to be used as a
valid support for 24-bit color. (Bug#44950)
* doc/lispref/display.texi (Xwidgets): Document new function.
* etc/NEWS: Announce new function.
* src/xwidget.c (Fxwidget_webkit_load_html): New function.
(syms_of_xwidget): Define new subr.
* src/w32font.c (w32_decode_weight, w32_encode_weight)
(w32_to_fc_weight): Adjust weight translations to match those in
font.c and gtkutil.c:xg_weight_to_symbol. (Bug#51704)
* src/xwidget.c (record_osr_embedder, from_embedder, to_embedder): New
functions.
(Fmake_xwidget): Attach from-embedder and to-embedder signals.
(find_widget_for_offscreen_window): New function.
(xwidget_button, xwidget_motion_or_crossing): Set embedder on event.
(Fdelete_xwidget_view): Remove embedder status if applicable.
* src/xwidget.h (struct xwidget): New fields `embedder' and
`embedder-view'.
