Do not show warning when using super in GenServer.child_spec/1
Support the new handle_continue/2 callback on Erlang/OTP 21+
Warn if super is used in any of the GenServer callbacks

Raise a more meaningful exit if you try to GenServer.call/3 yourself
Ensures cast/2 returns :ok if locally registered process is not found
Add GenServer.stop/1 for shutting down servers reliably
