> Frame unwinding requested by jvmtiPopFrame() function is established by suspended thread itself during it's staying in safe point. For this purpose safe point callback can be used.
> See HARMONY-1420 for brief top-level pop frame implementation design.
> Proposed patch:
> 1. Exports hythread_set_safepoint_callback() from thead manager.
> 2. Implements the callback function to perform frame unwinding.
> 3. Adds poppable attribute to those m2n frames that can be popped.
