Make PerformJoin responsible for sending invite to RS input (#1277)

Browse source 
* Make PerformJoin send input membership event

* Invite input room events in separate goroutine

* Don't limit roomserver input events using request context

* Synchronous input room events

* Nope, that didn't work

* oops send state key to GetMembership

* Don't generate stripped state in client API more times than necessary, generate output events on receiving end of federated invite

* Commit membership updater changes

* Tweaks
