Currently we have a rblist__delete() which is used to delete a rblist.
While rblist__delete() will free the pointer of rblist at the end.
It's inconvenience for user to delete a rblist which is not allocated
by something like malloc(). For example, the rblist is defined in a
data structure.
This patch creates a new function rblist__exit() which is similar
as rblist__delete() but it will not free the pointer of rblist.
