Speed up state res in rare case we don't have all events (#16116)
If we don't have all the auth events in a room then not all state events will have a chain cover index. Even so, we can still use the chain cover index on the events that do have it, rather than bailing and using the slower functions.

This situation should not arise for newly persisted rooms, as we check we have the full auth chain for each event, but can happen for existing rooms.

Fix database performance of read/write worker locks (#16061)
We were seeing serialization errors when taking out multiple read locks.

The transactions were retried, so isn't causing any failures.

Introduced in #15782.

Allow config of the backoff algorithm for the federation client. (#15754)
Adds three new configuration variables:

* destination_min_retry_interval is identical to before (10mn).
* destination_retry_multiplier is now 2 instead of 5, the maximum value will
  be reached slower.
* destination_max_retry_interval is one day instead of (essentially) infinity.

Capping this will cause destinations to continue to be retried sometimes instead
of being lost forever. The previous value was 2 ^ 62 milliseconds.

Re-introduce the outbound federation proxy (#15913)
Allow configuring the set of workers to proxy outbound federation traffic through (`outbound_federation_restricted_to`).

This is useful when you have a worker setup with `federation_sender` instances responsible for sending outbound federation requests and want to make sure *all* outbound federation traffic goes through those instances. Before this change, the generic workers would still contact federation themselves for things like profile lookups, backfill, etc. This PR allows you to set more strict access controls/firewall for all workers and only allow the `federation_sender`'s to contact the outside world.

Remove experimental MSC2716 implementation to incrementally import history into existing rooms (#15748)
Context for why we're removing the implementation:

 - https://github.com/matrix-org/matrix-spec-proposals/pull/2716#issuecomment-1487441010
 - https://github.com/matrix-org/matrix-spec-proposals/pull/2716#issuecomment-1504262734

Anyone wanting to continue MSC2716, should also address these leftover tasks: https://github.com/matrix-org/synapse/issues/10737

Closes https://github.com/matrix-org/synapse/issues/10737 in the fact that it is not longer necessary to track those things.

Modify StoreKeyFetcher to read from server_keys_json. (#15417)
Before this change:

* `PerspectivesKeyFetcher` and `ServerKeyFetcher` write to `server_keys_json`.
* `PerspectivesKeyFetcher` also writes to `server_signature_keys`.
* `StoreKeyFetcher` reads from `server_signature_keys`.

After this change:

* `PerspectivesKeyFetcher` and `ServerKeyFetcher` write to `server_keys_json`.
* `PerspectivesKeyFetcher` also writes to `server_signature_keys`.
* `StoreKeyFetcher` reads from `server_keys_json`.

This results in `StoreKeyFetcher` now using the results from `ServerKeyFetcher`
in addition to those from `PerspectivesKeyFetcher`, i.e. keys which are directly
fetched from a server will now be pulled from the database instead of refetched.

An additional minor change is included to avoid creating a `PerspectivesKeyFetcher`
(and checking it) if no `trusted_key_servers` are configured.

The overall impact of this should be better usage of cached results:

* If a server has no trusted key servers configured then it should reduce how often keys
  are fetched.
* if a server's trusted key server does not have a requested server's keys cached then it
  should reduce how often keys are directly fetched.

Fix spinloop during partial state sync when a prev event is in backoff (#15351)
Previously, we would spin in a tight loop until
`update_state_for_partial_state_event` stopped raising
`FederationPullAttemptBackoffError`s. Replace the spinloop with a wait

Delete stale non-e2e devices for users, take 3 (#15183)
This should help reduce the number of devices e.g. simple bots the repeatedly login rack up.

We only delete non-e2e devices as they should be safe to delete, whereas if we delete e2e devices for a user we may accidentally break their ability to receive e2e keys for a message.

Attempt to delete more duplicate rows in receipts_linearized table. (#14915)
The previous assumption was that the stream_id column was unique
(for a room ID, receipt type, user ID tuple), but this turned out to be
incorrect.

Now find the max stream ID, then map this back to a database-specific
row identifier and delete other rows which match the (room ID, receipt type,
user ID) tuple, but *not* the row ID.

Make sqlite database migrations transactional again, part two (#14926)
#14910 fixed the regression introduced by #13873 where sqlite database
migrations would no longer run inside a transaction. However, it
committed the transaction before Synapse updated its bookkeeping of
which migrations have been run, which means that migrations may be run
again after they have completed successfully.

Leave the transaction open at the end of `executescript`, to restore the
old, correct behaviour. Also make the PostgreSQL behaviour consistent
with SQLite.

Fixes #14909.
