When native_cond_timedwait() return 0 by spurious wakeup, we
don't have to neither 1) call timer_thread_function and 2)
exit the timer thread.

APIs to modularize GVL implementation.
* thread_pthread.c, thread_pthread.h: Two GVL implementations.
(1) Simple locking GVL which is same as existing GVL.
(2) Wake-up queued threads. The wake-up order is simple FIFO.
(We can make several queues to support exact priorities, however
this causes some issues such as priority inversion and so on.)
This impl. prevents spin-loop (*1) caused on SMP environemnts.
*1: Only one Ruby thread acqures GVL again and again.
Bug #2359 [ruby-core:26694]
* thread_win32.c, thread_win32.h: Using simple lock
not by CRITICAL_SECTION but by Mutex.

* vm.c (ruby_vm_destruct): ditto.

* thread_pthread.c (get_stack, ruby_stack_overflowed_p): both side
should be same type. [Bug #3145]

patched by KOSAKI Motohiro [ruby-dev:40309]
* thread_pthread.c (ruby_init_stack): use get_stack
on platforms which have pthread_attr_get_np.
(FreeBSD, DragonFlyBSD and NetBSD)
This is because FreeBSD and DragonFly BSD must use
pthread_attr_get_np to get stack size of main thread,
but Mac OS X and Linux with LinuxThreads must use getrlimit.
