Make federation catchup send last event from any server. (#9640)
Currently federation catchup will send the last *local* event that we
failed to send to the remote. This can cause issues for large rooms
where lots of servers have sent events while the remote server was down,
as when it comes back up again it'll be flooded with events from various
points in the DAG.

Instead, let's make it so that all the servers send the most recent
events, even if its not theirs. The remote should deduplicate the
events, so there shouldn't be much overhead in doing this.
Alternatively, the servers could only send local events if they were
also extremities and hope that the other server will send the event
over, but that is a bit risky.

Ensure we use a copy of the event content dict before modifying it in serialize_event (#9585)
This bug was discovered by DINUM. We were modifying `serialized_event["content"]`, which - if you've got `USE_FROZEN_DICTS` turned on or are [using a third party rules module](17cd48fe51/synapse/events/third_party_rules.py (L73-L76)) - will raise a 500 if you try to a edit a reply to a message.

`serialized_event["content"]` could be set to the edit event's content, instead of a copy of it, which is bad as we attempt to modify it. Instead, we also end up modifying the original event's content. DINUM uses a third party rules module, which meant the event's content got frozen and thus an exception was raised.

To be clear, the problem is not that the event's content was frozen. In fact doing so helped us uncover the fact we weren't copying event content correctly.

Fix bad naming of storage function (#9637)
We had two functions named `get_forward_extremities_for_room` and
`get_forward_extremeties_for_room` that took different paramters. We
rename one of them to avoid confusion.

Prep work for removing `outlier` from `internal_metadata` (#9411)
* Populate `internal_metadata.outlier` based on `events` table

Rather than relying on `outlier` being in the `internal_metadata` column,
populate it based on the `events.outlier` column.

* Move `outlier` out of InternalMetadata._dict

Ultimately, this will allow us to stop writing it to the database. For now, we
have to grandfather it back in so as to maintain compatibility with older
versions of Synapse.

Pass SSO IdP information to spam checker's registration function (#9626)
Fixes https://github.com/matrix-org/synapse/issues/9572

When a SSO user logs in for the first time, we create a local Matrix user for them. This goes through the register_user flow, which ends up triggering the spam checker. Spam checker modules don't currently have any way to differentiate between a user trying to sign up initially, versus an SSO user (whom has presumably already been approved elsewhere) trying to log in for the first time.

This PR passes `auth_provider_id` as an argument to the `check_registration_for_spam` function. This argument will contain an ID of an SSO provider (`"saml"`, `"cas"`, etc.) if one was used, else `None`.

Don't go into federation catch up mode so easily (#9561)
Federation catch up mode is very inefficient if the number of events
that the remote server has missed is small, since handling gaps can be
very expensive, c.f. #9492.

Instead of going into catch up mode whenever we see an error, we instead
do so only if we've backed off from trying the remote for more than an
hour (the assumption being that in such a case it is more than a
transient failure).

Optimise missing prev_event handling (#9601)
Background: When we receive incoming federation traffic, and notice that we are missing prev_events from 
the incoming traffic, first we do a `/get_missing_events` request, and then if we still have missing prev_events,
we set up new backwards-extremities. To do that, we need to make a `/state_ids` request to ask the remote
server for the state at those prev_events, and then we may need to then ask the remote server for any events
in that state which we don't already have, as well as the auth events for those missing state events, so that we
can auth them.

This PR attempts to optimise the processing of that state request. The `state_ids` API returns a list of the state
events, as well as a list of all the auth events for *all* of those state events. The optimisation comes from the
observation that we are currently loading all of those auth events into memory at the start of the operation, but
we almost certainly aren't going to need *all* of the auth events. Rather, we can check that we have them, and
leave the actual load into memory for later. (Ideally the federation API would tell us which auth events we're
actually going to need, but it doesn't.)

The effect of this is to reduce the number of events that I need to load for an event in Matrix HQ from about
60000 to about 22000, which means it can stay in my in-memory cache, whereas previously the sheer number
of events meant that all 60K events had to be loaded from db for each request, due to the amount of cache
churn. (NB I've already tripled the size of the cache from its default of 10K).

Unfortunately I've ended up basically C&Ping `_get_state_for_room` and `_get_events_from_store_or_dest` into
a new method, because `_get_state_for_room` is also called during backfill, which expects the auth events to be
returned, so the same tricks don't work. That said, I don't really know why that codepath is completely different
(ultimately we're doing the same thing in setting up a new backwards extremity) so I've left a TODO suggesting
that we clean it up.

Link to the List user's media admin API from media Admin API docs (#9571)
Earlier [I was convinced](https://github.com/matrix-org/synapse/issues/9565) that we didn't have an Admin API for listing media uploaded by a user. Foolishly I was looking under the Media Admin API documentation, instead of the User Admin API documentation.

I thought it'd be helpful to link to the latter so others don't hit the same dead end :)

Prevent the config-lint script erroring out on any sample_config changes (#9562)
I noticed that I'd occasionally have `scripts-dev/lint.sh` fail when messing about with config options in my PR. The script calls `scripts-dev/config-lint.sh`, which attempts some validation on the sample config.

 It does this by using `sed` to edit the sample_config, and then seeing if the file changed using `git diff`.

The problem is: if you changed the sample_config as part of your commit, this script will error regardless.

This PR attempts to change the check so that existing, unstaged changes to the sample_config will not cause the script to report an invalid file.
