Add support for additional memory checks using AddressSanitizer.
When Emacs is compiled with AddressSanitizer support, enable
poisoning/unpoisoning freed/unused Lisp objects and other internal
memory management structures. If enabled, this will mark freed bytes
that have been put on free lists for future use and initially
allocated memory blocks/chunks as "poisoned", triggering an ASan error
if they are accessed improperly. Structures are unpoisoned when they
have been taken off their respective free lists. Additionally, add
optional macros for performing unaligned loads, which when enabled by
defining USE_SANITIZER_UNALIGNED_LOAD will use ASan provided functions
for loading from unaligned addresses, which may help catch bugs that
AddressSanitizer might otherwise miss.

* configure.ac: Check for the existence of address and common
sanitizer API headers.

* src/lisp.h (UNALIGNED_LOAD_SIZE): New macro. If enabled, and the
necessary sanitizer API is available, define it to
__sanitizer_unaligned_load(64|32) depending on the word size of the
architecture.

* src/fns.c [HAVE_FAST_UNALIGNED_ACCESS] (Fstring_lessp): Use
'UNALIGNED_LOAD_SIZE' to perform unaligned loads from the two strings.

* src/alloc.c (ASAN_POISON_ABLOCK, ASAN_UNPOISON_ABLOCK)
(ASAN_POISON_INTERVAL_BLOCK, ASAN_UNPOISON_INTERVAL_BLOCK)
(ASAN_POISON_INTERVAL, ASAN_UNPOISON_INTERVAL)

(ASAN_UNPOISON_VECTOR_BLOCK, ASAN_POISON_SYMBOL_BLOCK)
(ASAN_UNPOISON_SYMBOL_BLOCK, ASAN_POISON_SYMBOL)
(ASAN_UNPOISON_SYMBOL) [ADDRESS_SANITIZER]: New macros. When
address sanitization is enabled, define them to poison/unpoison
objects.

(lisp_align_malloc): Poison newly allocated blocks on `free_ablock',
unpoison ablocks taken from it respectively.
(lisp_align_free): Poison individual ablocks when they are put on the
free list, unpoison them when an entire `ablocks' chunk is being
freed.

(make_interval): Poison interval blocks on initial allocation,
unpoison individual intervals on allocation and removal from
`interval_free_list'.
(sweep_intervals): Unpoison interval blocks before sweeping, poison
dead/unmarked intervals.

(allocate_string): Poison string blocks on initial allocation,
unpoison Lisp_Strings on removal from the free list.
(allocate_string_data): Poison `sblock' data on initial allocation,
unpoison individual `sdata' contents on allocation or removal from the
free list. Call `ASAN_PREPARE_LIVE_SDATA' on the new `sdata' struct.
(sweep_strings): Unpoison string blocks before sweeping them,
poisoning dead strings and their sdata afterwards.
(compact_small_strings): Call `ASAN_PREPARE_LIVE_DATA' on the `sdata'
to where compacted strings to moved to.
(pin_string): Call `ASAN_PREPARE_DEAD_SDATA' on `old_sdata'.

(make_float): Poison float blocks on allocation, unpoisoning
individual Lisp_Floats on allocation or removal from
`float_free_list'.
(sweep_floats): Unpoison float blocks before sweeping, poison
dead/unmarked floats.

(free_cons): Poison `ptr'.
(Fcons): Poison cons blocks on allocation, unpoisoning individual
Lisp_Cons on allocation or removal from `cons_free_list'.
(sweep_conses): Poison dead/unmarked conses.

(setup_free_list): Poison vectors put on `vector_free_lists'.
(allocate_vector_from_block): Unpoison vectors taken from the free
list, poison excess vector bytes when vectors allocated from the free
list are larger than requested.
(sweep_vectors): Unpoison vector blocks before sweeping them.

(Fmake_symbol): Poison symbol blocks on initial allocation,
unpoisoning individual Lisp_Symbols on allocation or removal from
`symbol_free_list'.
(sweep_symbols): Unpoison symbol blocks before sweeping, poisoning
dead/unmarked symbols.

(live_string_holding, live_cons_holding, live_symbol_holding)
(live_float_holding): When compiling with address sanitization and GC
poisoning enabled, return NULL if the passed address is poisoned, or
if the Lisp object it resides in is poisoned, avoiding a
use-after-poison trigger if these functions are called on a pointer

244346c744 Reimplement Lisp_Object as pointer-to-incomplete
This makes Lisp_Object values opaque pointers instead of integers,
which helps avoid the same sort of typos that
CHECK_LISP_OBJECT_TYPE helps to avoid, without having to wrap
pointers inside structures.  This also looks forward to supporting
-fcheck-pointer-bounds.
* etc/DEBUG:
* src/.gdbinit (Lisp_Object_Printer.to_string):
Lisp_Object can be a pointer type now.
* src/alloc.c (macro_XPNTR, XPNTR):
* src/emacs-module.c (value_to_lisp_bits, lisp_to_value_bits):
* src/lisp.h (lisp_h_XLI, lisp_h_XIL):
(lisp_h_XUNTAG) [USE_LSB_TAG]:
(XUNTAG) [!USE_LSB_TAG]:
(Lisp_Object, TAG_PTR, make_lisp_symbol):
Support new Lisp_Object implementation as a pointer to an
incomplete type.  Keep pointers pointers, as much as possible.
* src/alloc.c (macro_XPNTR_OR_SYMBOL_OFFSET, XPNTR_OR_SYMBOL_OFFSET):
Remove.  All uses replaced by plain XPNTR.
* src/emacs-module.c: Work around GCC bug 83162.
* src/lisp.h (LISP_WORDS_ARE_POINTERS, lisp_h_XLP, lisp_h_XPL):
(XLP, XPL) [DEFINE_KEY_OPS_AS_MACROS]:
New macros.
(Lisp_Word, untagged_ptr, Lisp_Word_tag): New types.
(XLP, XPL): New inline functions.
(TAG_PTR): Now expands to an initializer, not an expression.
All uses changed.
(TAG_SYMOFFSET, XLI_BUILTIN_LISPSYM): Remove.  All uses removed.
(LISPSYM_INITIALLY): Redo in terms of the new TAG_PTR.
(NIL_IS_ZERO): Redo without XLI_BUILTIN_LISPSYM.
* src/xwidget.c (webkit_javascript_finished_cb): Use XPL
instead of XIL with a non-EMACS_INT arg.
(Fxwidget_webkit_execute_script): Use XLP instead of XLI
followed by two conversions.

bc511a64f6 Prefer HTTPS to FTP and HTTP in documentation
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.

a815e5f195 Remove interpreter’s byte stack
This improves performance overall on my benchmark on x86-64,
since the interpreted program-counter resides in a machine
register rather than in RAM.
* etc/DEBUG, src/.gdbinit: Remove xbytecode GDB command, as there
is no longer a byte stack to decode.
* src/bytecode.c (struct byte_stack, byte_stack_list)
(relocate_byte_stack): Remove.  All uses removed.
(FETCH): Simplify now that pc is now local (typically, in a
register) and no longer needs to be relocated.
(CHECK_RANGE): Remove.  All uses now done inline, in a different way.
(BYTE_CODE_QUIT): Remove; now done by op_relative_branch.
(exec_byte_code): Allocate a copy of the function’s bytecode,
so that there is no problem if GC moves it.
* src/lisp.h (struct handler): Remove byte_stack member.
All uses removed.
* src/thread.c (unmark_threads): Remove.  All uses removed.
* src/thread.h (struct thread_state): Remove m_byte_stack_list member.
All uses removed.  m_stack_bottom is now the first non-Lisp field.
