Merge from gnulib: lib/gnulib.mk, m4/*.m4.

(open-network-stream): Add the keyword :always-query-capabilities.

This is for the case where you want to force a `plain' network
connection, but the protocol still requires the capabilitiy command
(i.e., SMTP and EHLO).

Integer overflow and signedness fixes (Bug#8873).

* ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.

(GET_CCL_RANGE, IN_INT_RANGE): Use it.

* fileio.c (emacs_lseek): Work around GCC bug 43772.

* character.h, charset.h: Use verify_expr, not verify_true.

Merge from trunk.

Refactor, replacing a sequence of nested if forms by a cond form.

Merge from trunk.

Renamed `process-alive-p' to `process-live-p' for consistency with other `-live-p' functions.

* window.el (display-buffer-alist): Trim default value to avoid
popping up a new frame (Bug#8857) or reusing an arbitrary window
on another frame.
(display-buffer): Do not fall back on popping up a new frame in
batch mode (Bug#8857).

* fileio.c: Don't assume EMACS_INT fits in off_t.

(emacs_lseek): New static function.
(Finsert_file_contents, Fwrite_region): Use it.
Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.

* fns.c (Fload_average): Don't assume 100 * load average fits in int.

* fns.c (Fcopy_sequence): Don't assume vector length fits in int.

* fns.c (Fnthcdr, Fsort): Don't assume list length fits in int.

* fns.c: Don't overflow int when computing a list length.

(Fsafe_length): Return a float if the value is not representable
as a fixnum.  This shouldn't happen except in contrived situations.
Use same QUIT_COUNT_HEURISTIC as Flength now does.

* fns.c (Flength): Don't overflow int when computing a list length.

Use EMACS_INT, not int, to avoid unwanted truncation on 64-bit hosts.
Check for QUIT every 1024 entries rather than every other entry;
that's faster and is responsive enough.  Report an error instead of
overflowing an integer.

* alloc.c: Check that resized vectors' lengths fit in fixnums.

(header_size, word_size): New constants.
(allocate_vectorlike): Don't check size overflow here.
(allocate_vector): Check it here instead, since this is the only
caller of allocate_vectorlike that could cause overflow.
Check that the new vector's length is representable as a fixnum.

Fix resize and change of scroll bar width for Gtk3.

* configure.in: Add emacsgtkfixed.o to GTK_OBJ if HAVE_GTK3.

* src/emacsgtkfixed.c, src/emacsgtkfixed.h: New files.

* src/gtkutil.c: Include src/emacsgtkfixed.h if HAVE_GTK3.
(int_gtk_range_get_value): Move to the scroll bar part of the file.
(style_changed_cb): Call update_theme_scrollbar_width and call
x_set_scroll_bar_default_width and xg_frame_set_char_size for
all frames.
(xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
Call gtk_window_set_resizable if HAVE_GTK3.
(x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
and height if HAVE_GTK3 (Bug#8505).
(scroll_bar_width_for_theme): New variable.
(update_theme_scrollbar_width): New function.
(xg_get_default_scrollbar_width): Move code to
update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
(xg_initialize): Call update_theme_scrollbar_width.

* src/gtkutil.h (xg_get_default_scrollbar_width): Remove argument.

* src/xfns.c (x_set_scroll_bar_default_width): Remove argument to
xg_get_default_scrollbar_width.

* fns.c (next_almost_prime): Don't return a multiple of 3 or 5.

The previous code was bogus.  For example, next_almost_prime (32)
returned 39, which is undesirable as it is a multiple of 3; and
next_almost_prime (24) returned 25, which is a multiple of 5 so
why was the code bothering to check for multiples of 7?

* bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.

* eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.

Merge from trunk.

Variadic C functions now count arguments with ptrdiff_t.

This partly undoes my 2011-03-30 change, which replaced int with size_t.
Back then I didn't know that the Emacs coding style prefers signed int.
Also, in the meantime I found a few more instances where arguments
were being counted with int, which may truncate counts on 64-bit
machines, or EMACS_INT, which may be unnecessarily wide.
* lisp.h (struct Lisp_Subr.function.aMANY)
(DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
Arg counts are now ptrdiff_t, not size_t.
All variadic functions and their callers changed accordingly.
(struct gcpro.nvars): Now size_t, not size_t.  All uses changed.
* bytecode.c (exec_byte_code): Check maxdepth for overflow,
to avoid potential buffer overrun.  Don't assume arg counts fit in 'int'.
* callint.c (Fcall_interactively): Check arg count for overflow,
to avoid potential buffer overrun.  Use signed char, not 'int',
for 'varies' array, so that we needn't bother to check its size
calculation for overflow.
* editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
* eval.c (apply_lambda):
* fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
(struct textprop_rec.argnum): Now ptrdiff_t, not int.  All uses changed.
(mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.

* callint.c (Fcall_interactively): Don't use index var as event count.

Print theme summaries in *Custom Themes* buffer.

* lisp/cus-theme.el (describe-theme-1): Use custom-theme-p.
(custom-theme-summary): New function.
(customize-themes): Use it.

* etc/themes/light-blue-theme.el:
* etc/themes/misterioso-theme.el:
* etc/themes/tango-dark-theme.el:
* etc/themes/tango-theme.el:
* etc/themes/tsdh-dark-theme.el:
* etc/themes/tsdh-light-theme.el:
* etc/themes/wheatgrass-theme.el:
* etc/themes/wombat-theme.el: Tweak summaries for better listability.

* etc/themes/dichromacy-theme.el: New theme.

* vm-limit.c (check_memory_limits): Fix incorrect extern function decls.

* mem-limits.h (SIZE): Remove; no longer used.

Merge from trunk.

cus-dep fix for build failure first occurring with 2011-06-13T08:21:09Z!rudalics@gmx.at

The symptom was `make custom-dep' failing with "Unknown terminal type".
This is caused by `display-buffer' trying to pop-up a frame in batch mode.
I think this cus-dep change may be just papering over the immediate
manifestation of the underlying problem.

* lisp/cus-dep.el (custom-make-dependencies): Use up command-line-args-left.

* xterm.c (x_alloc_nearest_color_1): Go back to original algorithm.

Make help and view-mode work with new buffer display facilities.

(help-window-setup-finish): Remove.
(help-window-display-message, help-window-setup)
(with-help-window): Major rewrite based on new
display-buffer-window variable.

* help-mode.el (help-mode-finish): Remove help-window related
code.

* view.el (view-exits-all-viewing-windows): Remove reference to
view-return-to-alist in doc-string.

(view-buffer-other-window): Call pop-to-buffer-other-window and
simplify code.  Ignore second argument.
(view-buffer-other-frame): Call pop-to-buffer-other-frame and
simplify code.  Ignore second argument.
(view-return-to-alist-update): Make obsolete.
(view-mode-enter): Rename second argument to QUIT-RESTORE.
Rewrite using quit-restore window parameters.
(view-mode-exit): Rename second argument to EXIT-ONLY.  Rewrite
using quit-restore-window.
(View-exit, View-exit-and-edit, View-leave, View-quit)
(View-quit-all, View-kill-and-leave): Call view-mode-exit with
appropriate arguments.

Merge from trunk.

* xterm.c (x_alloc_nearest_color_1): Use a more-precise algorithm

for nearest color, one that neither overflows nor relies on unsigned
arithmetic.

Remove unnecessary casts.

* xterm.c (x_term_init):
* xfns.c (x_set_border_pixel):
* widget.c (create_frame_gcs): Remove casts to unsigned long etc.
These aren't needed now that we assume ANSI C.

* sound.c (Fplay_sound_internal): Remove cast to unsigned long.

It's more likely to cause problems (due to unsigned overflow)
than to cure them.

* dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.

* unexelf.c (unexec): Don't assume BSS addr fits in unsigned.

* xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.

* keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.

* lisp.h (CHAR_TABLE_SET): Omit now-redundant test.

* lread.c (Fload): Don't compare a possibly-garbage time_t value.

GLYPH_CODE_FACE returns EMACS_INT, not int.

* dispextern.h (merge_faces):
* xfaces.c (merge_faces):
* xdisp.c (get_next_display_element):
(next_element_from_display_vector): Don't assume EMACS_INT fits in int.

* character.h (CHAR_VALID_P): Remove unused parameter.

* fontset.c, lisp.h, xdisp.c: All uses changed.

* editfns.c (Ftranslate_region_internal): Omit redundant test.

* fns.c (concat): Minor tuning based on overflow analysis.

This doesn't fix any bugs.  Use int to hold character, instead
of constantly refetching from Emacs object.  Use XFASTINT, not
XINT, for value known to be a character.  Don't bother comparing
a single byte to 0400, as it's always less.

* floatfns.c (Fexpt): Omit unnecessary cast to unsigned.

* fileio.c (make_temp_name): Omit unnecessary cast to unsigned.

* editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT

for characters.

* doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.

* data.c (Faset): If ARRAY is a string, check that NEWELT is a char.

Without this fix, on a 64-bit host (aset S 0 4294967386) would
incorrectly succeed when S was a string, because 4294967386 was
truncated before it was used.

* chartab.c (Fchar_table_range): Use CHARACTERP to check range.

Otherwise, an out-of-range integer could cause undefined behavior
on a 64-bit host.

* composite.c: Use int, not EMACS_INT, for characters.

(fill_gstring_body, composition_compute_stop_pos): Use int, not
EMACS_INT, for values that are known to be in character range.
This doesn't fix any bugs but is the usual style inside Emacs and
may generate better code on 32-bit machines.

Make sure a 64-bit char is never passed to ENCODE_CHAR.

This is for reasons similar to the recent CHAR_STRING fix.
* charset.c (Fencode_char): Check that character arg is actually
a character.  Pass an int to ENCODE_CHAR.
* charset.h (ENCODE_CHAR): Verify that the character argument is no
wider than 'int', as a compile-time check to prevent future regressions
in this area.

* character.c (char_string): Remove unnecessary casts.

Make sure a 64-bit char is never passed to CHAR_STRING.

Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
by silently ignoring the top 32 bits, allowing some values
that were far too large to be valid characters.
* character.h: Include <verify.h>.
(CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
arguments are no wider than unsigned, as a compile-time check
to prevent future regressions in this area.
* data.c (Faset):
* editfns.c (Fchar_to_string, general_insert_function, Finsert_char):
(Fsubst_char_in_region):
* fns.c (concat):
* xdisp.c (decode_mode_spec_coding):
Adjust to CHAR_STRING's new requirement.
* editfns.c (Finsert_char, Fsubst_char_in_region):
* fns.c (concat): Check that character args are actually
characters.  Without this test, these functions did the wrong
thing with wildly out-of-range values on 64-bit hosts.

Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.

These casts should not be needed on 32-bit hosts, either.
* keyboard.c (read_char):
* lread.c (Fload): Remove casts to unsigned.

* lisp.h (UNSIGNED_CMP): New macro.

This fixes comparison bugs on 64-bit hosts.
(ASCII_CHAR_P): Use it.
* casefiddle.c (casify_object):
* character.h (ASCII_BYTE_P, CHAR_VALID_P):
(SINGLE_BYTE_CHAR_P, CHAR_STRING):
* composite.h (COMPOSITION_ENCODE_RULE_VALID):
* dispextern.h (FACE_FROM_ID):
* keyboard.c (read_char): Use UNSIGNED_CMP.

* term/xterm.el (terminal-init-xterm): Still more simplifications.

* term/xterm.el (terminal-init-xterm): More simplifications.

* term/xterm.el (terminal-init-xterm): Misc simplifications.

* term/xterm.el (terminal-init-xterm): `version' may be nil.  (Bug#8838)

* tramp.texi (Customizing Completion): Mention authinfo-style files.
(Password handling): `auth-source-debug' is good for debug messages.

* leim/SKK-DIC/SKK-JISYO.L: Add proper coding tag.

* leim/MISC-DIC/cangjie-table.b5, leim/MISC-DIC/cangjie-table.cns,
* leim/MISC-DIC/pinyin.map, leim/MISC-DIC/ziranma.cin: Likewise.

Fix make_frame, introduce Vtemp_buffer_show_specifiers, cleanup doc-strings.

* frame.c (make_frame): Call other_buffer_safely instead of
other_buffer.

* window.c (temp_output_buffer_show): Call display_buffer with
second argument Vtemp_buffer_show_specifiers and reset latter
immediately after the call.
(Vtemp_buffer_show_specifiers): New variable.
(auto_window_vscroll_p, next_screen_context_lines)
(Vscroll_preserve_screen_position): Remove leading asterisks from
doc-strings.

* leim/Makefile.in (TIT_BIG5): Renamed from TIT-BIG5.

Restore window-safely-shrinkable-p but avoid using it in calendar.el.

* window.el (window-safely-shrinkable-p): Restore function which
was inadvertently removed in change from 2011-06-11.  Declare as
obsolete.

* calendar/calendar.el (calendar-generate-window): Use
window-iso-combined-p instead of combination of one-window-p and
window-safely-shrinkable-p.

Fix minor problems found by GCC 4.6.0 static checking.

* buffer.c (Qclone_number): Remove for now, as it's unused.
(record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
(record_buffer): Remove unused local.

if HAVE_GPM.
* menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
* process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
