Merge branch 'sv/sasl-fix-get_status' into dev
* sv/sasl-fix-get_status: Prepare patch release fix sys:get_status backward compatibility for sasl release_handler_1 OTP-8619 sv/sasl-fix-get_status In R13B04 sys:get_status was modified to invoke format_status/2 in the callback module if the module exports that function. This resulted in a change to the term returned from calling sys:get_status on the supervisor module, since supervisor is a gen_server and gen_server exports format_status. The sasl release_handler_1 module had a dependency on the pre-R13B04 term returned by sys:get_status when invoked on a supervisor, so the R13B04 change broke that dependency. This problem has been fixed by change release_handler_1 to handle both the pre-R13B04 and R13B04 terms that sys:get_status can return from a supervisor.
