Don't hold destination queues in memory forever (#1769)
* Don't hold destination queues in memory forever

* Close channels

* Wake queue when created, otherwise cleanup doesn't get called in all cases

* Clean up periodically, we hit a race condition otherwise

* Tweaks

* Don't create queues for blacklisted hosts

* Check blacklist properly

bugfix: continue sending PDUs if ones are added whilst sending another PDU (#1187)
* Add a bit more logging to the fedsender

* bugfix: continue sending PDUs if ones are added whilst sending another PDU

Without this, the queue goes back to sleep on `<-oq.notifyPDUs` which won't
fire because `pendingPDUs` is already > 0. This should fix a flakey sytest.

* Break if no txn is sent

* Tweak federation sender wake-ups

* Update comments

* Remove break or that'll kill the parent loop
