subscr_conn: introduce usage tokens for ref error tracking When hunting a conn use count bug, it was very hard to figure out who's (not) using the conn. To ease tracking down this bug and future bugs, explicitly name what a conn is being reserved for, and track in a bit mask. Show in the DREF logs what uses and un-uses a conn. See the test expectation updates, which nicely show how that clarifies the state of the conn in the logs. On errors, log them, but don't fail hard: if one conn use/un-use fails, we don't want to crash the entire MSC before we have to.
