This is a streamlined version of Lisp_Save_Value, which contains just
a pointer, as that is all Lisp_Save_Values are used for any more.
With the previous changes, these objects are not primarily used as
save values, so just call them "Misc" rather than "Save".
* src/alloc.c (make_misc_ptr): New function.
(mark_object): Mark Lisp_Misc_Ptr too.
* src/lisp.h (Lisp_Misc_Ptr): New constant.
(struct Lisp_Misc_Ptr): New type.
(make_mint_ptr, mint_ptrp, xmint_pointer):
Use Lisp_Misc_Ptr, not Lisp_Save_Value.
(union Lisp_Misc): Add Lisp_Misc_Ptr.
* src/print.c (print_object): Print Lisp_Misc_Ptr.
Instead of using __builtin_assume_aligned (P, GCALIGNMENT) to
tell GCC that P has alignment 8, use (T *) P where T is the
type of the pointed-to object, to tell GCC that P has native
alignment. This is simpler, matches the intent better, and
should help simplify future improvements. Some of these
changes are to pacify gcc -Wnull-dereference, since GCC is
smarter about pointers now that Emacs no longer uses
__builtin_assume_aligned; these minor changes should improve
code efficiency slightly. On Fedora 28 x86-64 with default
optimization this patch shrinks the size of the Emacs text
segment by 0.36%.
* src/conf_post.h (__has_builtin, __builtin_assume_aligned):
Remove; no longer used.
* src/dbusbind.c (XD_OBJECT_TO_DBUS_TYPE):
Pacify -Wnull-dereference by using XCAR instead of CAR_SAFE
and XCDR instead of CDR_SAFE when this is safe.
* src/fileio.c (Fexpand_file_name):
* src/font.c (clear_font_cache):
Pacify -Wnull-dereference by removing unnecessary NILP test.
* src/keyboard.c (xevent_start): New function.
(read_char, read_key_sequence): Pacify -Wnull-dereference by
using xevent_start instead of EVENT_START.
* src/lisp.h (lisp_h_XUNTAG): Remove; XUNTAG is always a macro
now, since it can no longer be implemented as a function.
(XUNTAG): New third argument CTYPE. All uses changed.
Cast result to CTYPE * instead of using __builtin_assume_aligned.
Simplify by using LISP_WORD_TAG.
(LISP_WORD_TAG): New macro.
(TAG_PTR): Use it.
* src/menu.c (x_popup_menu_1):
Pacify -Wnull-dereference by using XCAR instead of Fcar and
XCDR instead of Fcdr where this is safe.
Suggested by Eli Zaretskii (Bug#20890#31).
* src/font.h (font_data_structures_may_be_ill_formed): New function.
* src/ftfont.c (ftfont_close):
* src/ftcrfont.c (ftcrfont_close): Use it.
* src/lisp.h (vectorlike_headed): Change from struct to union.
All uses changed. Since it has only one member, this does not
change semantics. This is designed to simplify future changes
needed to fix bugs like Bug#29040. All uses changed.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
This simplifies the code a bit, and makes the structs more
shareable and less likely to become corrupt.

Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change

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.

Lisp_Object *, since Qfoo is no longer an object whose address can be
taken. All uses changed.
* eval.c (run_hook): New function. Most uses of Frun_hooks changed to
use it, so that they no longer need to take the address of a Lisp sym.
