* emacs.c (close_output_streams): Use strerror, not emacs_strerror,
as we can't assume that emacs_strerror is initialized, and strerror
is good enough here.
(main): Invoke atexit earlier, to catch earlier instances of
sending data to stdout and exiting, e.g., "emacs --version >/dev/full".

Fixes: debbugs:9574

(keyDown): Remap keypad keys to X11 virtual key codes.

Fixes: debbugs:8680

* admin/merge-gnulib (GNULIB_MODULES): Add close-stream.
* lib/close-stream.c, lib/close-stream.h, lib/fpending.c
* lib/fpending.h, m4/close-stream.m4, m4/fpending.m4:
New files, from gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* src/emacs.c: Include <close-stream.h>.
(close_output_streams): New function.
(main): Pass it to atexit, so that Emacs closes stdout and stderr
and handles errors appropriately.
(Fkill_emacs): Don't worry about flushing, as close_output_stream
does that now.

Fixes: debbugs:9574

The symptom is a diagnostic "GLib-WARNING **: In call to
g_spawn_sync(), exit status of a child process was requested but
SIGCHLD action was set to SIG_IGN and ECHILD was received by
waitpid(), so exit status can't be returned."  The diagnostic
is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
The real bug is a race condition between Emacs and glib: Emacs
does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
so that glib can't find it.  Work around the bug by invoking
waitpid only on subprocesses that Emacs itself creates.
* process.c (create_process, record_child_status_change):
Don't use special value -1 in pid field, as the caller now must
know the pid rather than having the callee infer it.  The
inference was sometimes incorrect anyway, due to another race.
(create_process): Set new 'alive' member if child is created.
(process_status_retrieved): New function.
(record_child_status_change): Use it.
Accept negative 1st argument, which means to wait for the
processes that Emacs already knows about.  Move special-case code
for DOS_NT (which lacks WNOHANG) here, from caller.  Keep track of
processes that have already been waited for, by testing and
clearing new 'alive' member.
(CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
now does this internally.
(handle_child_signal): Let record_child_status_change do all
the work, since we do not want to reap all exited child processes,
only the child processes that Emacs itself created.
* process.h (Lisp_Process): New boolean member 'alive'.

Fixes: debbugs:8855

* lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
(VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
Define only as macros.  There's no longer any need to also define
these symbols as enums or as constants, since we now assume
gcc -g3 when debugging.

* src/process.c (wait_reading_process_output): Avoid a race condition
with SIGIO delivery.

Fixes: debbugs:11536

* src/buffer.c (cursor_type): Untabify docstring.

Fixes: debbugs:11633

* widget.c (resize_cb): New function.
(EmacsFrameRealize): Add resize_cb as event handler.
(EmacsFrameResize): Check if all is up to date before changing frame
size.

Fixes: debbugs:12733

 src/xdisp.c (init_from_display_pos): Fix initialization of the bidi
 iterator when starting in the middle of a display or overlay
 string.

(FRAME_CAN_HAVE_SCROLL_BARS): Remove.

(Fwindow_body_width, Fwindow_body_height): Simplify a bit.
* font.c (Ffont_at): Likewise.

(EmacsFrameRealize): Add resize_cb as event handler.
(EmacsFrameResize): Check if all is up to date before changing frame

 src/w32fns.c (CaptureStackBackTrace_proc): New typedef.
 (BACKTRACE_LIMIT_MAX): New macro.
 (w32_backtrace): New function.
 (emacs_abort): Use w32_backtrace when the user chooses not to
 attach a debugger.  Update the text of the abort dialog.

* dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
Use decode_any_window.
* fringe.c (Ffringe_bitmaps_at_pos): Likewise.
* xdisp.c (Fformat_mode_line): Likewise.
* font.c (Ffont_at): Use decode_live_window.
* indent.c (Fcompute_motion, Fvertical_motion): Likewise.
* window.c (decode_next_window_args): Likewise.
(decode_any_window): Remove static.
* window.h (decode_any_window): Add prototype.
* lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
* window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
respectively.

* termhooks.h (struct input_event): Remove padding field.
Adjust comment.
* keyboard.c (event_to_kboard): Simplify because frame_or_window
member is never cons for a long time.  Adjust comment.
(mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
SELECTION_CLEAR_EVENT has no Lisp_Objects to mark.  Add comment.
* xterm.c (handle_one_xevent): Do not initialize frame_or_window
field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.

 src/w32proc.c (getpgrp, setpgid): New functions.

 nt/inc/unistd.h (setpgid, getpgrp): Provide prototypes.
 nt/config.nt (GETPGRP_VOID): Define to 1.

* callproc.c (setpgrp): Remove macro, as we now use setpgid
and it is configured in conf_post.h.
(Fcall_process): Don't invoke both setsid and setpgid; the former
is enough, if it exists.
* callproc.c (Fcall_process, child_setup):
* process.c (create_process): Use setpgid.
* conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
for the real thing.
* dispnew.c (init_display): Initialize the foreground group
if we are running a tty display.
* emacs.c (main): Do not worry about setpgrp; init_display does it now.
* lisp.h (init_foreground_group): New decl.
* sysdep.c (inherited_pgroup): New static var.
(init_foreground_group, tcsetpgrp_without_stopping)
(narrow_foreground_group, widen_foreground_group): New functions.
(init_sys_modes): Narrow foreground group.
(reset_sys_modes): Widen foreground group.

Fixes: debbugs:12697

* window.el (quit-restore-window): If the window has been
created on an existing frame and ended up as the sole window on
that frame, do not delete it (Bug#12764).

* minibuf.c (read_minibuf): Restore current buffer since
choose_minibuf_frame calling Fset_frame_selected_window may
change it (Bug#12766).

Fixes: debbugs:12733

font.c (Ffont_at): If WINDOW is specified and it is not displaying the current buffer, signal an error.

cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode): In
preparation for fixing bug#12739, move these functions from
here...

* coding.h, coding.c: ... to here, and compile them only when
WINDOWSNT or HAVE_NTGUI.  Moving these functions out of cygw32
proper lets us write cygw32-agnostic code for the HAVE_NTGUI case.

 src/w32proc.c (TIMER_TICKS_PER_SEC): New macro.
 (timer_loop, getitimer, setitimer): Use it instead of
 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
 'clock'.
 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
 literal 10000.

(last_appdefined_event_data): New variable
(last_appdefined_event): Remove.
(ns_select): Initialize t from last_appdefined_event_data instead
of [last_appdefined_event data1].
(sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
remove last_appdefined_event.

Fixes: debbugs:12698

 src/w32proc.c (sys_spawnve): Avoid compiler warning about format mismatch.
 (timer_loop): Remove unused variable.

 Avoid overflow in w32 implementation of interval timers.  When
 possible, for ITIMER_PROF count only times the main thread
 actually executes.

 src/w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
 ULONGLONG types.  Likewise for all the other data which was
 previously clock_t.
 (GetThreadTimes_Proc): New typedef.
 (w32_get_timer_time): New function, returns a suitable time value
 for the timer.
 (timer_loop): Enter critical section when accessing ULONGLONG
 values of the itimer_data struct, as these accesses are no longer
 atomic.  Call 'w32_get_timer_time' instead of 'clock'.
 (init_timers): Initialize s_pfn_Get_Thread_Times.
 (start_timer_thread): Don't assign itimer->caller_thread here.
 (getitimer): Assign itimer->caller_thread here.
 (setitimer): Always call getitimer to get the value of ticks_now.

 src/w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
 mouse movement events if the menu bar is active.  This avoids
 producing a busy "hour-glass" cursor by Windows if the mouse
 pointer is positioned over a tooltip shown for some menu item.

* emacs.c (shut_down_emacs) [!DOS_NT]:
* sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
* term.c (dissociate_if_controlling_tty) [!DOS_NT]:
Use pid_t, not int, to store process IDs, as 'int'
is not wide enough on a few platforms (e.g., AIX and IRIX).

* display.texi (Font Lookup): Remove font-list-limit.

* lisp/startup.el (command-line):
* lisp/cus-start.el: Don't refer to font-list-limit.

* lisp/faces.el (font-list-limit): Define as an obsolete variable.

* xfaces.c (Vfont_list_limit): Move unused variable to faces.el.

(nsfont_draw): Turn off LCD-smoothing.
