Put a bit less pressure on the garbage collector by defining a
macro that is like AUTO_STRING but also allows null bytes in strings,
and by extending AUTO_STRING to work with any unibyte string.

Use AUTO_STRING if possible. This is doable more often now
that AUTO_STRING works on any unibyte string.
Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.
Omit ‘#include "foo.h"’ unless the file needs foo.h (Bug#21707).
In a few cases, add ‘#include "foo.h"’ if the file needs foo.h
but does not include it directly. As a general rule, a source
file should include foo.h if it needs the interfaces that foo.h
defines.

Although \( is needed in docstrings in Elisp code, it is not needed in
docstrings in C code, since C function definitiions do not start with
a parenthesis. The backslashes made the docstrings a bit harder to
read and to format in columns. Also, some C docstrings had ( in
column 1 and this did not appear to be causing any problems. So,
simplify C docstrings by replacing \( with ( and \) with ).
This removes the need for GCPRO1 etc. Suggested by Stefan Monnier in:
http://lists.gnu.org/archive/html/emacs-devel/2015-08/msg00918.html
* doc/lispref/internals.texi (Writing Emacs Primitives):

* src/eval.c (gcpro_level) [DEBUG_GCPRO]:

(BYTE_MARK_STACK, GCPRO1, GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6)
(GCPRO7, UNGCPRO, RETURN_UNGCPRO):
Remove. All uses removed. The code now assumes
GC_MARK_STACK == GC_MAKE_GCPROS_NOOPS.
* src/bytecode.c (relocate_byte_stack):
Rename from unmark_byte_stack, since it now only relocates.
All callers changed.
* src/frame.c (make_frame): Add an IF_LINT to pacify GCC 5.2
with GCPROs removed.
* src/systime.h: Use EMACS_LISP_H as the canary instead of GCPRO1.

* doc/lispref/internals.texi (Stack-allocated Objects):
Adjust to match the revised, less error-prone macros.
* src/frame.h (AUTO_FRAME_ARG): Rename from FRAME_PARAMETER.
* src/lisp.h (AUTO_CONS): Rename from scoped_cons.
(AUTO_LIST1): Rename from scoped_list1.
(AUTO_LIST2): Rename from scoped_list2.
(AUTO_LIST3): Rename from scoped_list3.
(AUTO_LIST4): Rename from scoped_list4.
(AUTO_STRING): Rename from SCOPED_STRING.
* src/frame.h (AUTO_FRAME_ARG):
* src/lisp.h (AUTO_CONS, AUTO_LIST1, AUTO_LIST2, AUTO_LIST3)
(AUTO_LIST4, AUTO_STRING):
Prepend a new argument 'name'.
Declare a variable instead of yielding a value.
All uses changed.
* src/lisp.h (STACK_CONS, AUTO_CONS_EXPR): New internal macros.
The build_local_string macro was used in two ways: (1) string
literals for which scoped allocation suffices, and (2) file name
components, where it's not safe in general to assume bounded-size
ASCII data. Simplify by defining a new macro SCOPED_STRING that
allocates a block-scope string, and by using SCOPED_STRING for (1)
and build_string for (2). Furthermore, actually use stack
allocation only for objects known to have sufficient alignment.
This simpler implementation means Emacs can make
USE_STACK_LISP_OBJECTS the default unless GC_MARK_STACK !=
GC_MAKE_GCPROS_NOOPS.
* lisp.h (GCALIGNED): Align even if !USE_STACK_LISP_OBJECTS,
for fewer differences among implementations.
(struct Lisp_String): Now GCALIGNED.
(USE_STACK_LISP_OBJECTS): Default to true, since the
implementation no longer insists on a nonempty GCALIGNED.
But make it false if GC_MARK_STACK != GC_MAKE_GCPROS_NOOPS.
(SCOPED_CONS_INITIALIZER): Remove, since it's no longer needed
separately. Move definiens to scoped_cons. The old definition
was incorrect when GCALIGNED was defined to be empty.
(union Aligned_String): New type.
(USE_STACK_CONS, USE_STACK_STRING): New constants, so that the
implementation ports to compilers that don't align strictly enough.
Don't worry about the union sizes; it's not worth bothering about.
(scoped_cons, scoped_list1, scoped_list3, scoped_list4):
Rewrite using USE_STACK_CONS.
(scoped_cons): Assume the use of union Aligned_Cons.
(lisp_string_size, make_local_string, build_local_string): Remove.
Unless otherwise specified, all callers of build_local_string
changed to use SCOPED_STRING.
(SCOPED_STRING): New macro.
* data.c (wrong_choice):
* menu.c (single_menu_item):
* process.c (Fformat_network_address):
Hoist use of SCOPED_STRING out of a scope, so that its returned
object lives long enough.
* fileio.c (Fexpand_file_name): Use build_string, not SCOPED_STRING,
as the string might be long or might not be ASCII.
* configure.ac (HAVE_STATEMENT_EXPRESSIONS): Remove.
For USE_STACK_LISP_OBJECTS, we always assume __GNUC__.
* lisp.h (union Aligned_Cons) [!GCALIGNED]: Define as such.
(SCOPED_CONS_INITIALIZER): New macro.
(scoped_cons) [USE_STACK_LISP_OBJECTS]: Use it.
(USE_LOCAL_ALLOCA): Remove.
(local_cons, local_list1, local_list2, local_list3, local_list4):
Remove. Stack overflow checking makes them too slow.
(make_local_vector): Likewise. Also we just don't have enough
users for it.
(enum LISP_STRING_OVERHEAD): Remove.
(local_string_init, local_vector_init): Remove prototypes.
(make_local_string, build_local_string): Redesign to target short
compile-time string constants, fall back to regular string allocation
where appropriate.
(lisp_string_size): New function.
(verify_ascii) [ENABLE_CHECKING]: Add prototype.
* alloc.c (local_string_init, local_vector_init): Remove.

* coding.c (MAX_LOOKUP_MAX): New constant.

This fixes a portability problem, namely, alloca result
passed to another function. All uses changed.

not MAX_ALLOCA - 1.

(call_process_cleanup) [MSDOS]: Ifdef away portions not relevant
for MSDOS.
(call_process) [MSDOS]: Fix call sequence of dostounix_filename.
Use temporary file template that is compatible with mkostemp.
Move vfork-related portions under #ifndef MSDOS.
(syms_of_callproc): Unify templates of MSDOS and WINDOWSNT.
lisp/term/pc-win.el (x-list-fonts, x-get-selection-value): Provide
doc strings, as required by snarf-documentation.

msdos/sed1v2.inp: Update Sed scripts for Emacs 24.4.
msdos/inttypes.h: Add PRIdMAX.
msdos/INSTALL: Update for Emacs 24.4.
msdos/sedadmin.inp: New file.
src/w32menu.c (w32_popup_dialog): Don't condition the whole function
on HAVE_DIALOGS. If the dialog is "simple", pop up a message box
to show it; otherwise return 'unsupported--w32-dialog' to signal
to the caller that emulation with menus is necessary. This
resurrects code inadvertently deleted by the 2013-10-08 commit.
(syms_of_w32menu): DEFSYM Qunsupported__w32_dialog.
src/w32term.h (w32_popup_dialog): Prototype is no longer conditioned
by HAVE_DIALOGS.
src/menu.c (Fx_popup_dialog): Don't condition the call to
w32_popup_dialog on HAVE_DIALOGS. If w32_popup_dialog returns a
special symbol 'unsupported--w32-dialog', emulate the dialog with
a menu by calling x-popup-menu.
src/menu.h (Qunsupported__w32_dialog): New extern variable.
src/menu.c (Fx_popup_menu): When invoking tty_menu_show, temporarily
switch to single keyboard. Prevents daemon crashes when a new
client connects while we show a TTY menu in an existing client.
* buffer.h (struct buffer_text, struct buffer):
* frame.h (struct frame):
* window.h (struct window):
Avoid 'bool foo : 1;', as it's not portable to pre-C99 compilers,
as described in ../lib/stdbool.in.h. Use 'unsigned foo : 1;' instead.
* menu.c (syms_of_menu): Define x-popup-dialog, removing a
no-longer-valid use of HAVE_MENUS.
* xdisp.c (propagate_buffer_redisplay): Now static.
* dispnew.c (save_current_matrix): Omit unnecessary casts.
* dispnew.c (update_frame_with_menu): Mark debug local as used.
* keyboard.c, keyboard.h (Qmouse_movement): Now static.
* keyboard.c (read_menu_command): Remove unused local.
* lisp.h (read_menu_command): New decl.
* menu.c, menu.h (menu_item_width): Arg is now unsigned char *, for
benefit of STRING_CHAR_AND_LENGTH. All uses changed.
Return ptrdiff_t, not int.
* term.c (tty_menu_struct): 'allocated' member is now ptrdiff_t,
not int, for benefit of xpalloc.
(tty_menu_create, tty_menu_make_room): Simplify by using xzalloc
and xpalloc.
(have_menus_p): Remove; unused.
(tty_menu_add_pane, tty_menu_add_selection): Change signedness of
local char * pointer to pacify STRING_CHAR_AND_LENGTH.
(tty_menu_add_selection, tty_menu_locate, tty_meny_destroy):
Now static.
(save_and_enable_current_matrix): Omit unnecessary casts.
(read_menu_input): Omit local extern decl (now in lisp.h).
Don't access uninitialized storage if mouse_get_xy fails.
(tty_menu_activate): Mark local as initialized, for lint.
(tty_menu_activate, tty_meny_show): Remove unused locals.
