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.

Merge from trunk.

* movemail.c: Fix race condition and related bugs (Bug#8836).

(main) [!MAIL_USE_SYSTEM_LOCK]: Prefer mkstemp to mktemp, as this
fixes some race conditions.  Report mkstemp/mktemp errno rather
than a possibly-garbage errno.  Reinitialize the template each
time through the loop, as earlier mkstemp/mktemp calls could have
trashed it.  Pass 0600 (not 0666) to mktemp, for consistency
with mkstemp; the permissions don't matter anyway.

* image.c (gif_load): Fix omitted cast error introduced by 2011-06-06 change.

 src/ window.c (resize_window_apply): Make definition be "static" to
 match the prototype.

Move window resize code from window.c to window.el.

* alloc.c (inhibit_garbage_collection): Set gc_cons_threshold to max value.

Previously, this ceilinged at INT_MAX, but that doesn't work on
64-bit machines.

* alloc.c (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.

* alloc.c: (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)

(n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
These were 'int' variables that could overflow on 64-bit hosts;
they were never used, so remove them instead of repairing them.

* alloc.c: Use EMACS_INT, not int, to count objects.

(total_conses, total_markers, total_symbols, total_vector_size)

(total_free_floats, total_floats, total_free_intervals, total_intervals)
(total_strings, total_free_strings):
Now EMACS_INT, not int.  All uses changed.
(Fgarbage_collect): Compute overall total using a double, so that
integer overflow is less likely to be a problem.  Check for overflow
when converting back to an integer.

* alloc.c (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT

when a (possibly-narrower) signed value would do just as well.
We prefer using signed arithmetic, to avoid comparison confusion.

* alloc.c (allocate_vectorlike): Check for ptrdiff_t overflow.

* alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.

* alloc.c: Catch some string size overflows that we were missing.

(XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
for convenience in STRING_BYTES_MAX.
(STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
The definition here is exact; the one in lisp.h was approximate.
(allocate_string_data): Check for string overflow.  This catches
some instances we weren't catching before.  Also, it catches
size_t overflow on (unusual) hosts where SIZE_MAX <= min
(PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
and ptrdiff_t and EMACS_INT are both 64 bits.
* character.c, coding.c, doprnt.c, editfns.c, eval.c:

Qget_mru_window, Qresize_root_window,
Qresize_root_window_vertically, Qsafe, Qabove, Qbelow,
Qauto_buffer_name; staticpro them.

A few new functions and rewrites in window.el.
