process.c: rb_daemon should not raise
* process.c (rb_daemon): should not raise exceptions, since
proc_daemon() will deal with errors.
* process.c (fork_daemon): kill the other threads all and abandon the
kept mutexes.
* process.c (fork_daemon): kill the other threads all and abandon the
kept mutexes.
* process.c (rb_daemon): daemon(3) is implemented with fork(2).
Therefore it needs rb_thread_atfork(). (and revert r41903)

* process.c (redirect_dup2): set standard handles when new fd is stdio,
because if there is no allocated console at the moment Windows does
not automatically associate it for child process's standard handle.
this is adhoc workaround.
reported by Martin Thiede at [ruby-core:48542] [Bug #7239].
* io.c (rb_cloexec_dup2): ditto.

* include/ruby/win32.h (rb_w32_aspawn_flags): add the declaration of
new function.
* process.c (enum): add EXEC_OPTION_PGROUP and move the position
above for the usage in proc_spawn_n().
* process.c (proc_spawn_n): add an argument to pass new option
`new_pgroup`. The option specifies CREATE_NEW_PROCESS_GROUP flag to
CreateProcessW(). This flag is necessary for the usage of
Process.kill on the subprocess on Windows.
* process.c (rb_exec_arg_addopt): ditto.
* process.c (rb_spawn_process): ditto.
* process.c (documentation for rb_f_spawn): add documentation for new
option `new_pgroup` of spawn.
* test/ruby/test_process.rb (TestProcess#test_execopts_new_pgroup):
add tests for option `new_pgroup`.
* test/ruby/test_thread.rb
(TestThreadGroup#test_thread_timer_and_interrupt):
add option `new_pgroup: true` to spawn on Windows. It's needed for
Process.kill on a subprocess.
* win32/win32.c (CreateChild): add an argument to pass
dwCreationFlags of CreateProcessW().
* win32/win32.c (rb_w32_spawn): ditto.
* win32/win32.c (rb_w32_aspawn_flags): add new function to pass
dwCreationFlags.
* win32/win32.c (rb_w32_aspawn): refactor to move the content to
rb_w32_aspawn_flags().
[ruby-core:43245][Bug #6131]
* test/ruby/test_thread.rb
(TestThreadGroup#test_thread_timer_and_interrupt): skip on Windows.
Process.kill cannot kill a subprocess if CREATE_NEW_PROCESS_GROUP
flag is not specified in a call to CreateProcessW().
* win32/win32.c (CreateChild): revert the usage of
CREATE_NEW_PROCESS_GROUP flag for compatibility.

spawned process.
* process.c (proc_spawn_v): fix missing argument, and try with
/bin/sh only if failed with ENOEXEC.

no waiting thread. If there are 2 or more runnable threads,
the timer thread does polling. Avoid polling makes power save
for several computers (0.2W per a Ruby process, when I measured).
If outside-event such as signal or Thread#kill was occuerred
when the timer thread does not do polling, then wake-up
the timer thread using communication-pipe (the timer thread
waits this communication-pipe with select(2)).
The discussion about this modification can be found from the post
[ruby-core:33456] and other related posts.
Note that Eric Wong and KOSAKI Motohiro give us the huge
contributions for this modification. Thanks.
* thread_pthread.c (rb_thread_wakeup_timer_thread): add a function.
This function wakes up the timer thread using communication-pipe.
* thread.c (rb_thread_stop_timer_thread): add a parameter which
specify closing communication-pipe or not.
* thread.c (rb_thread_terminate_all): do not stop timer thread here
(ruby_cleanup() terminate timer thread).
* signal.c: wake up timer thread using
rb_thread_wakeup_timer_thread() from signal handler.
* eval.c (ruby_cleanup): use rb_thread_stop_timer_thread(1).
* process.c: use rb_thread_stop_timer_thread(0)
(reuse communication-pipe).
* thread_win32.c (rb_thread_wakeup_timer_thread): add a dummy
function.
* vm_core.h: add and fix decl. of functions.

for avoiding a race.
* process.c (sig_do_nothing): new function.

* compile.c, eval.c, iseq.c, object.c, parse.y, proc.c, process.c,
thread.c, vm.c, vm_eval.c, vm_insnhelper.c, vm_method.c: don't
declare internal functions.
Note that rb_method_entry_eq() is defined in vm_method.c but
there was a declaration in proc.c with different const-ness.
Now it is declared in method.h with same const-ness to the
definition.
* object.c (rb_mod_module_exec): don't declare functions declared in
include/ruby/intern.h.

before calling execve(). Because r31760 reintroduced an issue that
system() may hang up (i.e. [ruby-dev:12261]).
* process.c (save_sigpipe, restore_sigpipe): new.

this also supports Windows which doesn't have sysconf(3).
* process.c (maxgroups): use get_sc_ngroups_max.
* process.c (proc_setmaxgroups): ditto.

ArgumentError if fd >= 3 on Windows because the feature is not
supported.
* test/ruby/test_process.rb (test_execopts_redirect): remove meaningless
argument.

* process.c (rb_exec_arg_addopt): Use NUM2MODET() instead
NUM2LONG because clang makes compile error by this narrowing
conversion.
* process.c (rb_run_exec_options_err): ditto.
