Function makeObjectShared

Set a special refcount in the object to make it "shared": * incrRefCount and decrRefCount() will test for this special refcount * and will not touch the object. This way it is free to access shared * objects such as small integers from different threads without any * mutex. * * A common patter to create shared objects: * * robj *myobject = makeObjectShared(createObject(...)); * */
