Federation sender refactor (#1621) 

* Refactor federation sender, again

* Clean up better

* Missing operators

* Try to get overflowed events from database

* Fix queries

* Log less

* Comments

* nil PDUs/EDUs shouldn't happen but guard against them for safety

* Tweak logging

* Fix transaction coalescing

* Update comments

* Check nils more

* Remove channels as they add extra complexity and possibly will deadlock

* Don't hold lock while sending transaction

* Less spam about sleeping queues

* Comments

* Bug-fixing

* Don't try to rehydrate twice

* Don't queue in memory for blacklisted destinations

* Don't queue in memory for blacklisted destinations

* Fix a couple of bugs

* Check for duplicates when pulling things out of the database

* Durable transactions, some more refactoring

* Revert "Durable transactions, some more refactoring"

This reverts commit 5daf924eaaefec5e4f7c12c16ca24e898de4adbb.

* Fix deadlock
