(query-replace-read-from): Add the last incremental search string
to the list of default values accessible via M-n.
(map-query-replace-regexp): Use `read-regexp'.
(query-replace, query-replace-regexp, query-replace-regexp-eval)
(map-query-replace-regexp, replace-string, replace-regexp):
Fix docstrings to replace mentions of `query-replace-interactive'
with alternatives.

OpenBSD problem reported by Han Boetes.
* profiler.c (setup_cpu_timer): Check for failure of timer_settime
and/or setitimer.
(Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
* syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
like OpenBSD, which has timer_settime but does not declare it.
OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
whether to use itimerspec-related primitives. All uses of
HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
* progmodes/python.el (python-syntax-propertize-function):
Simplify and enhance the regexp for unescaped quotes. Now it also
matches quotes in weird situations like the single quote in
"something\"'".
(python-syntax-stringify): Simplify num-quotes detecting code.
src/w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
consistent with the change in return value of 'safe_strsignal'.
nt/preprep.c (RVA_TO_PTR): Cast the result to 'void *', to avoid
compiler warnings when using the value.
* lisp/profiler.el (profiler-sampling-interval): Change units
from ms to ns, multiplying the default by 1000000 so that
it remains 1 ms.
(profiler-report-cpu-line-format): Give enough room for
the maximum counters on 64-bit hosts.
(profiler-report-render-calltree-1): Call them "CPU samples",
not "Time (ms)", since they are not milliseconds now (and
never really were).
* src/profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
Give extra weight to samples after overruns, to attempt to count
the time more accurately.
(setup_cpu_timer): Change sampling interval units from ms to ns, since
the underlying primitives nominally do ns.
(Fprofiler_cpu_start): Document the change. Mention that
the sampling intervals are only approximate.
* src/buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
(Fmake_overlay): Remove redundant tests.
* src/coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
case for the special 0 coding-system.
* src/frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
* lisp/vc/log-edit.el (log-edit-font-lock-keywords): Allow hyphens in
header names.
(log-edit-toggle-header): New function.
(log-edit-extract-headers): Accept function values in HEADERS alist.
* lisp/vc/vc-git.el (vc-git-log-edit-toggle-signoff): New function.
(vc-git-log-edit-toggle-amend): New function.
(vc-git-log-edit-toggle-signoff): New function.
(vc-git-log-edit-mode): New major mode.
(vc-git-log-edit-mode-map): Keymap for it.
(vc-git-checkin): Handle "Amend" and "Sign-Off" headers.
A signal can arrive in the middle of a malloc, and Emacs's signal
handler can invoke strsignal, which can invoke malloc, which is
not portable. This race condition bug makes Emacs hang on GNU/Linux.
Fix it by altering the signal handler so that it does not invoke
strsignal.
* emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
* process.c (status_message): Use const pointer, in case strsignal
is #defined to safe_strsignal.
* sysdep.c (sys_siglist, init_signals): Always define and
initialize a substitute sys_siglist if the system does not define
one, even if HAVE_STRSIGNAL.
(safe_strsignal): Rename from strsignal. Always define,
using sys_siglist. Return a const pointer.
* syssignal.h (safe_strsignal): New decl.
(strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
lib-src/make-docfile.c (write_globals): Special-case
Fexit_recursive_edit and Fabort_recursive_edit as well, as
functions that are _Noreturn, to be consistent with
src/keyboard.c.
nt/preprep.c (RVA_TO_PTR): Use 'unsigned char *' instead of
'void *', for pointer arithmetics.
(OFFSET_TO_RVA, RVA_TO_OFFSET, RVA_TO_SECTION_OFFSET): Enclose all
macro arguments in parentheses.
src/unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
(RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
(RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
as the previous version used 'void *'.
src/ralloc.c (ROUNDUP): Fix last change.
(MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
'size_t'.
Fixes: debbugs:12544
src/w32proc.c (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
return results.
[!HAVE_SETITIMER]: Behave as the previous version that didn't
support timers.
src/w32proc.c <disable_itimers>: New static flag.
(init_timers): Initialize it to zero, after creating the critical
sections used by the timer threads.
(term_timers): Set to 1 before deleting the critical sections.
(getitimer, setitimer): If disable_itimers is non-zero, return an
error indication without doing anything. Reported by Fabrice
Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
