* src/process.c (wait_reading_process_output) [WINDOWSNT]:
* src/keyboard.c (handle_async_input) [DOS_NT]: Ifdef away the
code that is not needed on MS-Windows. (Bug#50403) (Bug#51820)
* src/keyboard.c (handle_async_input): Call gobble_input
unconditionally, not just if USABLE_SIGIO is defined. This makes
process_pending_signals do something useful on systems that have
to poll for input. (Bug#51820)
* src/process.c (wait_reading_process_output) [!USABLE_SIGIO]: If
we're waiting for input, don't use a timeout of more than 25 msec
in the call to select. (Bug#50043)
This serves to eliminate the huge black bar displayed when the
offscreen widget has been resized (and as such the damage event
signal is sent), but the X window hasn't.

* src/callproc.c (emacs_spawn) <fork_done>: Define the label only
if USABLE_POSIX_SPAWN is defined, to avoid a compiler warning.
(cherry picked from commit a8fc080851)
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.
Backported from commit a60053f836.
Unlike that commit, only define USABLE_POSIX_SPAWN on macOS, because
there posix_spawn is much faster than vfork.
Don't merge to master.
* 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

(emacs_spawn): Use posix_spawn if possible.
(cherry picked from commit a60053f836)
* 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.
