Various changes:
- removed "in_use" from being passed to ATS, no longer needed as we tell ATS when we cannot follow a suggestion by removing the address; simplifies the code a lot - better handling of state machine, fallback to primary session if address switch to new session timed out - nicer logging - more comments - new testcase failures, because of #3652, #3651 and #3650 (or more that i missed).
