Ensure Rollback Mechanism:
A rollback's function is a function to rollback a state before ensure's
function execution.
When the jump of callcc is across the scope of rb_ensure,
ensure's functions and rollback's functions are executed appropriately
for keeping consistency.
Current API is unstable, and only internal use.
ruby_register_rollback_func_for_ensure(ensure_func,rollback_func)
This API create relation ensure's function to rollback's function.
By registered rollback's function, it is executed When jumpping into
corresponding rb_ensure scope.
