RefPtr should have a release method

[imtrobin]

Hi, like std unique_ptr, RefPtr should have a release method so we can manage the smart ptr ourselves

@imtrobin please give more description, for example why need this, what will happen if not

Now, it seem like assigning it to null ,but std ptr do not allow this kind of auto conversions because it is potentiall dangerous as it prevents some accidental pointer conversions.

There are some old discussions on why std ptr is designed to be explicit,
