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.

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-return-to-alist): Make obsolete.
(view-buffer): Call pop-to-buffer-same-window and remove
undo-window code.
(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.
(view-end-message): Use quit-restore window parameter.

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.

(Vscroll_preserve_screen_position): Remove leading asterisks from
doc-strings.

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
