 src/xfaces.c (x_free_gc) [HAVE_X_WINDOWS, HAVE_NTGUI]: Don't pass

not int, for benefit of xpalloc.
(tty_menu_create, tty_menu_make_room): Simplify by using xzalloc
and xpalloc.

* xdisp.c (redisplay_internal): When updating all frames with zero
windows_or_buffers_changed, assume that only the windows that shows
current buffer should be really updated.

for file I/O, thus reducing an enormous memory usage for large buffers.
See http://lists.gnu.org/archive/html/emacs-devel/2013-10/msg00180.html.
* coding.h (struct coding_system): New member raw_destination.

All uses of 'size_t' and 'SIZE_MAX' changed to use them, when
they're talking about words in Lisp bool vectors.
(BITS_PER_BITS_WORD): Rename from BITS_PER_SIZE_T.  All uses changed.

Do this by using the Gnulib modules for this.
This should generate faster code on non-GCC, non-MSC platforms,
and make the code a bit more portable, at least in theory.

(popcount_size_t_msc, popcount_size_t_gcc):
Remove; now done by Gnulib.
(popcount_size_t): Now a macro that defers to Gnulib.
(count_trailing_zero_bits): Return int, for consistency with
Gnulib and because Emacs prefers signed to unsigned int.
Don't assume that size_t is either unsigned int or unsigned long
or unsigned long long.
(size_t_to_host_endian): Do not assume that size_t is either
exactly 32 or exactly 64 bits wide.
* src/lisp.h (BITS_PER_SIZE_T): Define consistently with BITS_PER_LONG
etc., so that it's now an enum constant, not a macro.
No need to assume that it's either 32 or 64.

on >= 10.7.

Use bool for boolean.

* alloc.c (valid_pointer_p) [!WINDOWSNT]: Remove now-unnecessary cast.
* sysdep.c (emacs_read, emacs_write, emacs_write_sig):
Buffer arg is now void *, not char *.  This matches plain
'read' and 'write' better, and avoids a constraint violation
on Solaris 9 with Oracle Studio.

memset to explicit loop.  Otherwise copy largest possible chunk
from initialized to uninitialized part, thus allowing the longer
memcpy runs and reducing the number of loop iterations.

(ns_update_auto_hide_menu_bar): Remove runtime check.
Don't auto hide dock unless menubar is also auto hidden.

hide toolbar.
(windowDidEnterFullScreen:): If presentation options are zero,
set them here (Bug#15388).

uses find_newline instead of scan_newline and so doesn't move point.

On Fedora 19 x86-64, the new bswap_64 needs 1 instruction,
whereas the old swap64 needed 30.
* admin/merge-gnulib (GNULIB_MODULES): Add byteswap.

Use byteswap.h's macros to swap bytes.
* src/lisp.h (swap16, swap32, swap64): Remove.
All uses replaced by bswap_16, bswap_32, bswap_64.

to work around local variables getting clobbered by longjmp.
Port to pre-C99, which doesn't allow decls after stmts.

In other words, take on the behavior of eassert_and_assume.
This makes Emacs 0.2% smaller on my platform (Fedora 19, x86-64).
(eassert_and_assume): Remove.  All uses replaced by eassert.

* src/conf_post.h (__has_builtin, assume): Remove; gnulib now does these.
* src/lisp.h: Include <verify.h>, for 'assume'.

This also incorpoprates:
2013-10-02 verify: new macro 'assume'

(handlerlist, lisp_eval_depth): Not static any more.
(internal_catch, internal_condition_case, internal_condition_case_1)
