Let we make adaptor invalidate if adaptor stop

Let we make adaptor invalidate if adaptor stop

There was some issue when we try to destruct some singletone class
during application shutting down.

Since Adaptor still available, some singletone class try to access another
singletone class inside of it's destructor. It might make some problem.

To avoid it, let we check that adaptor is stopped at IsAvailable() API.

And also, Let we clean-up all registered processor at Stop timing,
to avoid unmatched behaviour after we change IsAvailable return false even
Core alive.
