The one hardship is that lazy-loading updates must NOT affect the order
tracker, otherwise its internal state will be incorrect (disynchronized
from the store) and thus return incorrect values upon shrink/lazy-load.
In this specific case, some updates must be ignored, the same way we do
it for the store using `let _ = store_updates().take()` in a few places.
The author considered that a right place where to flush the pending
updates was at the same time we flushed the updates-as-vector-diffs,
since they would be observable at the same time.
This is a new data structure that will help figuring out a local,
absolute ordering for events in the current linked chunk. It's designed
to work even if the linked chunk is being lazily loaded, and it provides
a few high-level primitives that make it possible to work nicely with
the event cache.
In the next patch, we're going to introduce another user of
`UpdatesToVectorDiff` which doesn't require accumulating the
`VectorDiff` updates; so as to make it optional, let's generalize the
algorithm with a trait, that carries the same semantics.
No changes in functionality.
It doesn't belong there anymore, because it's not used within the event
cache itself. It's used in the timeline, and I think it's nice to keep
it available for external users as well, so it now lives in its own
`matrix-sdk/src/paginators` module. Next step is to move the thread
loader in there as well.
It avoids using different versions in several places for consistency. It
also allows to be able to change it in a single place when needed.
This also bumps the fallback to v11 everywhere, since it is the default
version for new rooms since Matrix 1.14 and it has the sanest redaction
rules.

Process:
- set style_edition to 2024 in .rustfmt.toml
- run `cargo fmt`
- undo .rustfmt.toml change
- run `cargo fmt` again
- manually rewrap some strings
The `/auth_metadata` endpoint has been supported by Synapse for 6 months
now so there shouldn't be any homeserver that still depend exclusively
on it. This endpoint is also part of Matrix 1.15.
Support for this endpoint has been removed from Ruma so this is
necessary before an upgrade of the dependency.

It turns out that downstream clients can and do call
`Client::join_room_by_id()` rather than `Room::join`, so we need to do
the room key history import in the lower-level method.

The previous code would parse the entire bundled event, only to look at
its type indirectly. We can do better than this, and only look at the
type instead. This brings a few benefits:
- it is faster, as we don't have to deserialize the entire event
- while the spec seems to indicate that the latest thread event has a
`room_id`, it seems that, under some circumstances, it does not, as
indicated by some rageshakes. As such, not parsing as `AnyMessageLike`
(which mandates a room id) makes it more robust to the absence of a
room id in there, marking more events as latest events.
This prevents us from having to add type constraints on the dynamic type
and instead only having to specify the type constraint at the call site.

This can be used to invalidate the persisted state on disk related to
the sliding sync positions. It's useful to do so when clearing up all
the caches, since the sliding sync `pos`itions are stored in the crypto
store (to benefit from the cross-process lock).
