RB_RESERVED_FD_P): added. This C API is to limit to access
fds which are used by RubyVM internal. In this version of
CRuby, return 1 if fd is communication pipe.
If your application needs to close all file descriptors to
preent resource leak, skip internal fds using this C API.
We also define a macro RB_RESERVED_FD_P(fd). So you can write
#ifndef RB_RESERVED_FD_P
#define RB_RESERVED_FD_P(fd) 0
#endif
for Ruby 1.9.2 or previous version to write compatible extensions.
See [ruby-core:37727]
* thread_win32.c (rb_reserved_fd_p): added (return 0 for any fds).
* io.c (rb_io_initialize): raise ArgumentError if given fd is reserved by Ruby.

return stack start addres, but stack base address. Thus,
we need to add stack size for getting stack start address.
And, we don't have to decrease guard size twice.
* thread_pthread.c (thread_start_func_1): don't use inaccurate
stack start guess if native_thread_init_stack() can be used.

OS X. [Bug #1813] [ruby-core:24540]
* signal.c (ruby_signal): SIGBUS use alternative stack too.
* signal.c (sigbus): On Mac, thread stack overflow makes SIGBUS
instead of SIGSEGV. thus, added stackoverflow check.
* signal.c (default_handler): get rid of compilation warning.
* signal.c (Init_signal): ditto.

In timer thread, signal handler shoul use it.
The patch is contributed by Eric Wong <normalperson@yhbt.net>.
Refs: [ruby-core:37644] and [ruby-core:37647]
* thread_pthread.c: use rb_async_bug_errno().
And replace all fprintf() to write().

Make "buff" as static. (Maybe) "buff" can be shared between
any caller (any threads) because no one use the read values.
And remove const value "buff_size", and define CCP_READ_BUFF_SIZE
macro.

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.

* thread.c (rb_thread_stop_timer_thread): add a parameter which
specify closing communication-pipe or not.

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.
