Merge tag 'v1.87.0' into develop

Please note that this will be the last release of Synapse that is compatible with
Python 3.7 and earlier.
This is due to Python 3.7 now having reached End of Life; see our [deprecation policy](https://matrix-org.github.io/synapse/v1.87/deprecation_policy.html)
for more details.

- Pin `pydantic` to `^1.7.4` to avoid backwards-incompatible API changes from the 2.0.0 release.
  Resolves matrix-org#15858.
  Contributed by @PaarthShah. ([\matrix-org#15862](matrix-org#15862))

- Split out 2022 changes from the changelog so the rendered version in GitHub doesn't timeout as much. ([\matrix-org#15846](matrix-org#15846))

- Improve `/messages` response time by avoiding backfill when we already have messages to return. ([\matrix-org#15737](matrix-org#15737))
- Add spam checker module API for logins. ([\matrix-org#15838](matrix-org#15838))

- Fix a long-standing bug where media files were served in an unsafe manner. Contributed by @joshqou. ([\matrix-org#15680](matrix-org#15680))
- Avoid invalidating a cache that was just prefilled. ([\matrix-org#15758](matrix-org#15758))
- Fix requesting multiple keys at once over federation, related to [MSC3983](matrix-org/matrix-spec-proposals#3983). ([\matrix-org#15770](matrix-org#15770))
- Fix joining rooms through aliases where the alias server isn't a real homeserver. Contributed by @tulir @ Beeper. ([\matrix-org#15776](matrix-org#15776))
- Fix a bug in push rules handling leading to an invalid (per spec) `is_user_mention` rule sent to clients. Also fix wrong rule names for `is_user_mention` and `is_room_mention`. ([\matrix-org#15781](matrix-org#15781))
- Fix a bug introduced in 1.57.0 where the wrong table would be locked on updating database rows when using SQLite as the database backend. ([\matrix-org#15788](matrix-org#15788))
- Fix Sytest environmental variable evaluation in CI. ([\matrix-org#15804](matrix-org#15804))
- Fix forgotten rooms missing from initial sync after rejoining them. Contributed by Nico from Famedly. ([\matrix-org#15815](matrix-org#15815))
- Fix sqlite `user_filters` upgrade introduced in v1.86.0. ([\matrix-org#15817](matrix-org#15817))

- Document `looping_call()` functionality that will wait for the given function to finish before scheduling another. ([\matrix-org#15772](matrix-org#15772))
- Fix a typo in the [Admin API](https://matrix-org.github.io/synapse/latest/usage/administration/admin_api/index.html). ([\matrix-org#15805](matrix-org#15805))
- Fix typo in MSC number in faster remote room join architecture doc. ([\matrix-org#15812](matrix-org#15812))

- Remove experimental [MSC2716](matrix-org/matrix-spec-proposals#2716) implementation to incrementally import history into existing rooms. ([\matrix-org#15748](matrix-org#15748))

- Replace `EventContext` fields `prev_group` and `delta_ids` with field `state_group_deltas`. ([\matrix-org#15233](matrix-org#15233))
- Regularly try to send transactions to other servers after they failed instead of waiting for a new event to be available before trying. ([\matrix-org#15743](matrix-org#15743))
- Fix requesting multiple keys at once over federation, related to [MSC3983](matrix-org/matrix-spec-proposals#3983). ([\matrix-org#15755](matrix-org#15755))
- Allow for the configuration of max request retries and min/max retry delays in the matrix federation client. ([\matrix-org#15783](matrix-org#15783))

 This is called a **faster join**, also known as a **partial join**. In these
 notes we'll usually use the word "partial" as it matches the database schema.

+
+_First introduced in Synapse v1.87.0_
+
+```python
+async def check_login_for_spam(
+    user_id: str,
+    device_id: Optional[str],
+    initial_display_name: Optional[str],
+    request_info: Collection[Tuple[Optional[str], str]],
+    auth_provider_id: Optional[str] = None,
+) -> Union["synapse.module_api.NOT_SPAM", "synapse.module_api.errors.Codes"]
+```
+
+Called when a user logs in.
+
+The arguments passed to this callback are:
+
+* `user_id`: The user ID the user is logging in with
+* `device_id`: The device ID the user is re-logging into.
+* `initial_display_name`: The device display name, if any.
+* `request_info`: A collection of tuples, which first item is a user agent, and which
+  second item is an IP address. These user agents and IP addresses are the ones that were
+  used during the login process.
+* `auth_provider_id`: The identifier of the SSO authentication provider, if any.
+
+If multiple modules implement this callback, they will be considered in order. If a
+callback returns `synapse.module_api.NOT_SPAM`, Synapse falls through to the next one.
+The value of the first callback that does not return `synapse.module_api.NOT_SPAM` will
+be used. If this happens, Synapse will not call any of the subsequent implementations of
+this callback.
+
+*Note:* This will not be called when a user registers.

+### `federation`
+
+The federation section defines some sub-options related to federation.
+
+The following options are related to configuring timeout and retry logic for one request,
+independently of the others.
+Short retry algorithm is used when something or someone will wait for the request to have an
+answer, while long retry is used for requests that happen in the background,
+like sending a federation transaction.
+
+* `client_timeout`: timeout for the federation requests. Default to 60s.
+* `max_short_retry_delay`: maximum delay to be used for the short retry algo. Default to 2s.
+* `max_long_retry_delay`: maximum delay to be used for the short retry algo. Default to 60s.
+* `max_short_retries`: maximum number of retries for the short retry algo. Default to 3 attempts.
+* `max_long_retries`: maximum number of retries for the long retry algo. Default to 10 attempts.
+
+Example configuration:
+```yaml
+federation:
+  client_timeout: 180s
+  max_short_retry_delay: 7s
+  max_long_retry_delay: 100s
+  max_short_retries: 5
