Cheng Zhao 06cf0406fe Dereference remote objects with native code
Previously we rely on the v8util.setDestructor to dereference the remote
objects in JavaScript, however as documented in V8, it is forbidden to
call V8 APIs in object's destructor (e.g. the weak callback), and doing
so would result in crashs.

This commit removes the JavaScript setDestructor method, and avoids
doing the dereference work with V8.
