merge revision(s) r34038,34099:

* thread_pthread.c (ubf_select): call rb_thread_wakeup_timer_thread()
	  only when it is not timer_thread. [Bug #5757] [ruby-dev:44985]
	  patched by Tomoyuki Chikanaga.

	* thread_pthread.c (ping_signal_thread_list): remove return value.

	* thread_pthread.c (check_signal_thread_list): add a new function to
	  check if signal thread list is empty.

	* thread_pthread.c (thread_timer): check signal thread list after
	  timer_thread_function(). main thread might be added into signal thread
	  list during timer_thread_function().
