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.

* 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.

profiler-sample-interval.
(profiler-sampling-interval): Default to 10.

(profiler-find-profile-other-window): New command.
(profiler-find-profile-other-frame): New command.
(profiler-profile): Introduce API-level data structure.

src/w32proc.c (sig_mask, crit_sig): New static variables.
(sys_signal): Support SIGALRM and SIGPROF.
(sigemptyset, sigaddset, sigfillset, sigprocmask)
(pthread_sigmask, setpgrp): Moved here from w32.c. sigaddset,
sigfillset, and sigprocmask are no longer no-ops.
(sigismember): New function.
(struct itimer_data): New definition.
(ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)
(crit_prof): New static variables.
(MAX_SINGLE_SLEEP): New definition.
(timer_loop, stop_timer_thread, term_timers, init_timers)
(start_timer_thread, getitimer, setitimer): New functions.
(alarm): No longer a no-op, calls setitimer.
src/w32.c (term_ntproc): Call term_timers.
(init_ntproc): Make sure all signals are unblocked at startup, to
erase any traces of dumping. Call init_timers.
src/w32fns.c (hourglass_timer, HOURGLASS_ID): Remove.
Windows-specific code to display the hourglass mouse pointer is no
longer used.
(w32_wnd_proc): Remove code that handled the WM_TIMER message due
to hourglass timer expiration.
(start_hourglass, cancel_hourglass, DEFAULT_HOURGLASS_DELAY):
Remove, no longer used.
(w32_note_current_window, show_hourglass, hide_hourglass): New
functions, in support of hourglass cursor display similar to other
window systems.
(syms_of_w32fns): Don't initialize hourglass_timer.
src/xdisp.c (start_hourglass, cancel_hourglass): Now used on
WINDOWSNT as well.
(start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
src/w32.h (init_timers, term_timers): Add prototypes.
nt/inc/sys/time.h (ITIMER_REAL, ITIMER_PROF): Define.
(struct itimerval): Define.
(getitimer, setitimer): Add prototypes.
nt/inc/ms-w32.h <sigset_t> [_MSVC_VER]: Make the typedef consistent
with MinGW.
(SA_RESTART, SIGPROF): Define.
nt/config.nt (HAVE_SETITIMER): Define to 1.

src/profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
HAVE_TIMER_SETTIME is defined.

* profiler.c: Don't include stdio.h, limits.h, sys/time.h,
signal.h, setjmp.h. Include systime.h instead.
(saturated_add): New function.
(record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
(record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
(profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
New static vars.
(enum profiler_cpu_running): New enumn.
(profiler_cpu_running): Now of that enum type, not bool.
All uses changed to store the new value.
(handle_profiler_signal): Rename from sigprof_handler_1,
for consistency with other handlers. Do not check whether
cpu_log is a hash-table if garbage collecting, since it
doesn't matter in that case.
(deliver_profiler_signal): Rename from sigprof_handler,
for consistency with other handlers.
(setup_cpu_timer): New function, with much of what used to be in
Fprofiler_cpu_start. Check for out-of-range argument.
Prefer timer_settime if available, and prefer
thread cputime clocks, then process cputime clocks, then
monotonic clocks, to the old realtime clock. Use make_timeval
to round more-correctly when falling back to setitimer.
(Fprofiler_cpu_start): Use it.
(Fprofiler_cpu_stop): Prefer timer_settime if available.
Don't assume that passing NULL as the 2nd argument of setitimer
is the same as passing a pointer to all-zero storage.
Ignore SIGPROF afterwards.
(malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
* sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
non-fatal signal handlers. Ignore SIGPROF on startup.
* syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
in profiler.c, since sysdep.c now uses it.

(profiler-reset, profiler--report-cpu): Don't signal an error if the
cpu profiler is not available.

if it wasn't.

* src/profiler.c (evict_lower_half): Fix typo.
(PROFILER_CPU_SUPPORT): Check and define if cpu-profiler is supported.
Don't compile the cpu-profiler code, if not supported.

* src/lisp.h (sample_profiler_running, gc_probe): Don't declare.
