ruby_vm_global_state_version and related macros
from vm_core.h to vm_insnhelper.h.

when ruby_vm_global_state_version overflows.
TODO: vm_clear_all_inline_method_cache() is only place holder.
We need to implement it ASAP.
* vm_method.c (vm_clear_global_method_cache): added.

possible for an object to survive until its surrounding object
space is about to be freed. Those objects, if any, remains not
leaked for the rest of a process life. This is problematic
because for instance a T_DATA object may have its own destructor
to terminate something.
* vm.c (ruby_vm_destruct): ruby_current_vm termination should be
somewhere after rb_objspace_free for above reason.

hook a VM termination. Right now, because the VM we have is
process global, most extensions do not deallocate resources and
leave them to Operating System's reaping userland processes. But
in a future we plan to have multiple VMs to run simultaneously in
a single process (MVM project). At that stage we can no longer
rely on OSes and have to manage every resources to be reclaimed
properly. So it is. For a forward-compatibility reason this API
is introduced now, encouraging you to be as gentle as you can for
your resources; that is, tidy up your room.
* include/ruby/vm.h: ditto.
* vm_core.h (rb_vm_struct): new field.
* vm.c (vm_init2): initialize above new field.

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.

added. Unlinked method entries are collected to
vm->unlinked_method_entry_list. On the GC timing, mark all method
entries which are on all living threads. Only non-marked method
entries are collected. This hack prevents releasing living method
entry.
[Performance Consideration] Since this Method Entry GC (MEGC)
doesn't occuer frequently, MEGC will not be a performance bottleneck.
However, to traverse living method entries, every control frame push
needs to clear cfp->me field. This will be a performance issue
(because pushing control frame is occurred frequently).

* cont.c (fiber_init): init cfp->me.
* gc.c (garbage_collect): kick rb_sweep_method_entry().
* method.h (rb_method_entry_t): add a mark field.
* vm.c (invoke_block_from_c): set passed me.
* vm.c (rb_thread_mark): mark cfp->me.
* vm_core.h (rb_thread_t): add a field passed_me.

* vm_insnhelper.c (vm_push_frame): clear cfp->me at all times.
