* thread.c, vm_core.h: make gvl_acquire/release/init/destruct
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.
Bug #3890 [ruby-dev:42315]
* vm.c (ruby_vm_destruct): ditto.
