Here we split on_receive_pdu into two functions (on_receive_pdu and process_pulled_event), rather than having both cases in the same method. There's a tiny bit of overlap, but not that much.
If the new /hierarchy API does not exist on all destinations,
fallback to querying the /spaces API and translating the results.
This is a backwards compatibility hack since not all of the
federated homeservers will update at the same time.
* Include outlier status in `str(event)`
In places where we log event objects, knowing whether or not you're dealing
with an outlier is super useful.
* Remove duplicated logging in get_missing_events
When we process events received from get_missing_events, we log them twice
(once in `_get_missing_events_for_pdu`, and once in `on_receive_pdu`). Reduce
the duplication by removing the logging in `on_receive_pdu`, and ensuring the
call sites do sensible logging.
* log in `on_receive_pdu` when we already have the event
* Log which prev_events we are missing
* changelog
Instead of wrapping the JSON into an object, this creates concrete
instances for Transaction and Edu. This allows for improved type
hints and simplified code.
If the federation client receives an M_UNABLE_TO_AUTHORISE_JOIN or
M_UNABLE_TO_GRANT_JOIN response it will attempt another server
before giving up completely.
Improves type hints for:
* parse_{boolean,integer}
* parse_{boolean,integer}_from_args
* parse_json_{value,object}_from_request
And fixes any incorrect calls that resulted from unknown types.
This is to help with performance, where trying to connect to thousands
of hosts at once can consume a lot of CPU (due to TLS etc).

Fixes#9490
This will break a couple of SyTest that are expecting failures to be added to the response of a federation /send, which obviously doesn't happen now that things are asynchronous.
Two drawbacks:
Currently there is no logic to handle any events left in the staging area after restart, and so they'll only be handled on the next incoming event in that room. That can be fixed separately.
We now only process one event per room at a time. This can be fixed up further down the line.
The idea here is to stop people sending things that aren't joins/leaves/knocks through these endpoints: previously you could send anything you liked through them. I wasn't able to find any security holes from doing so, but it doesn't sound like a good thing.
* Room version 7 for knocking.
* Stable prefixes and endpoints (both client and federation) for knocking.
* Removes the experimental configuration flag.

Also add support for giving a callback to generate the JSON object to
verify. This should reduce memory usage, as we no longer have the event
in memory in dict form (which has a large memory footprint) for extend
periods of time.
