Use fully-qualified PersistedEventPosition when returning RoomsForUser (#17265)
Use fully-qualified `PersistedEventPosition` (`instance_name` and `stream_ordering`) when returning `RoomsForUser` to facilitate proper comparisons and `RoomStreamToken` generation.

Fix deduplicating of membership events to not create unused state groups. (#17164)
We try and deduplicate in two places: 1) really early on, and 2) just
before we persist the event. The first case was broken due to it
occuring before the profile information was added, and so it thought the
event contents were different.

The second case did catch it and handle it correctly, however doing so
creates a redundant state group leading to bloat.

Fixes #3791

Replaces all usages of StreamIdGenerator with MultiWriterIdGenerator (#17229)
Replaces all usages of `StreamIdGenerator` with `MultiWriterIdGenerator`, which is safer.

Move towards using MultiWriterIdGenerator everywhere (#17226)
There is a problem with `StreamIdGenerator` where it can go backwards
over restarts when a stream ID is requested but then not inserted into
the DB. This is problematic if we want to land #17215, and is generally
a potential cause for all sorts of nastiness.

Instead of trying to fix `StreamIdGenerator`, we may as well move to
`MultiWriterIdGenerator` that does not suffer from this problem (the
latest positions are stored in `stream_positions` table). This involves
adding SQLite support to the class.

This only changes id generators that were already using
`MultiWriterIdGenerator` under postgres, a separate PR will move the
rest of the uses of `StreamIdGenerator` over.

Fix slipped logging context when media rejected (#17239)
When a module rejects a piece of media we end up trying to close the
same logging context twice.

Instead of fixing the existing code we refactor to use an async context
manager, which is easier to write correctly.

Support MSC3916 by adding unstable media endpoints to _matrix/client (#17213)
[MSC3916](https://github.com/matrix-org/matrix-spec-proposals/blob/rav/authentication-for-media/proposals/3916-authentication-for-media.md)
adds new media endpoints under `_matrix/client`. This PR adds the
`/preview_url`, `/config`, and `/thumbnail` endpoints. `/download` will
be added in a follow-up PR once the work for the federation `/download`
endpoint is complete (see
https://github.com/element-hq/synapse/pull/17172).

Should be reviewable commit-by-commit.

Add Sliding Sync /sync/e2ee endpoint for To-Device messages (#17167)
This is being introduced as part of Sliding Sync but doesn't have any sliding window component. It's just a way to get E2EE events without having to sit through a big initial sync  (`/sync` v2). And we can avoid encryption events being backed up by the main sync response or vice-versa.

Part of some Sliding Sync simplification/experimentation. See [this discussion](https://github.com/element-hq/synapse/pull/17167#discussion_r1610495866) for why it may not be as useful as we thought.

Bring auto-accept invite logic into Synapse (#17147)
This PR ports the logic from the
[synapse_auto_accept_invite](https://github.com/matrix-org/synapse-auto-accept-invite)
module into synapse.

I went with the naive approach of injecting the "module" next to where
third party modules are currently loaded. If there is a better/preferred
way to handle this, I'm all ears. It wasn't obvious to me if there was a
better location to add this logic that would cleanly apply to all
incoming invite events.

Relies on https://github.com/element-hq/synapse/pull/17166 to fix linter
errors.

Removed request_key from the SyncConfig (moved outside as its own function parameter) (#17201)
Removed `request_key` from the `SyncConfig` (moved outside as its own function parameter) so it doesn't have to flow into `_generate_sync_entry_for_xxx` methods. This way we can separate the concerns of caching from generating the response and reuse the `_generate_sync_entry_for_xxx` functions as we see fit. Plus caching doesn't really have anything to do with the config of sync.

Apply user email & picture during OIDC registration if present & selected (#17120)
This change will apply the `email` & `picture` provided by OIDC to the
new user account when registering a new user via OIDC. If the user is
directed to the account details form, this change makes sure they have
been selected before applying them, otherwise they are omitted. In
particular, this change ensures the values are carried through when
Synapse has consent configured, and the redirect to the consent form/s
are followed.

I have tested everything manually. Including: 
- with/without consent configured
- allowing/not allowing the use of email/avatar (via
`sso_auth_account_details.html`)
- with/without automatic account detail population (by un/commenting the
`localpart_template` option in synapse config).

Ensure that incoming to-device messages are not dropped (#17127)
... when workers are unreachable, etc.

Fixes https://github.com/element-hq/synapse/issues/17117.

The general principle is just to make sure that we propagate any
exceptions to the JsonResource, so that we return an error code to the
sending server. That means that the sending server no longer considers
the message safely sent, so it will retry later.

In the issue, Erik mentions that an alternative solution would be to
persist the to-device messages into a table so that they can be retried.
This might be an improvement for performance, but even if we did that,
we still need this mechanism, since we might be unable to reach the
database. So, if we want to do that, it can be a later follow-up.

55b0aa847a Fix GHSA-3h7q-rfh9-xm4v
Weakness in auth chain indexing allows DoS from remote room members
through disk fill and high CPU usage.

A remote Matrix user with malicious intent, sharing a room with Synapse
instances before 1.104.1, can dispatch specially crafted events to
exploit a weakness in how the auth chain cover index is calculated. This
can induce high CPU consumption and accumulate excessive data in the
database of such instances, resulting in a denial of service.

Servers in private federations, or those that do not federate, are not
affected.

bugfix: make msc3967 idempotent (#16943)
MSC3967 was updated recently to make it more robust to network failures:

> there is an existing cross-signing master key and it exactly matches
the cross-signing master key provided in the request body. If there are
any additional keys provided in the request (self signing key, user
signing key) they MUST also match the existing keys stored on the
server. In other words, the request contains no new keys. If there are
new keys, UIA MUST be performed.


https://github.com/matrix-org/matrix-spec-proposals/blob/hughns/device-signing-upload-uia/proposals/3967-device-signing-upload-uia.md#proposal

This covers the case where the 200 OK is lost in transit so the client
retries the upload, only to then get UIA'd.

Fix bug in /sync response for archived rooms (#16932)
This PR fixes a very, very niche edge-case, but I've got some more work
coming which will otherwise make the problem worse.

The bug happens when the syncing user leaves a room, and has a sync
filter which includes "left" rooms, but sets the timeline limit to 0. In
that case, the state returned in the `state` section is calculated
incorrectly.

The fix is to pass a token corresponding to the point that the user
leaves the room through to `compute_state_delta`.

Patch the db conn pool sooner in tests (#17017)
When running unit tests, we patch the database connection pool so that
it runs queries "synchronously". This is ok, except that if any queries
are launched before we do the patching, those queries get left in limbo
and never complete.

To fix this, let's change the way we do the switcheroo, by patching out
the method which creates the connection pool in the first place.
