This patch introduces `Chunk::lazy_previous` which is a key feature to
support lazy-loading of a `LinkedChunk`. When a chunk is loaded, if it
is the first, it keeps in memory whether it has a previous chunk or not.
Thus, it is possible to insert new chunk in front of the `LinkedChunk`,
and `Update`s will correctly continue to link chunks between them (with
`NewItemsChunk` and `NewGapChunk`).
Example, imagine the following chunks: [0] <-> [1] <-> [2]. If [2] is
the only one being loaded. Then its previous chunk, [1], is loaded from
the store (because [2]'s previous is [1] in the store). Then [1] is
replaced by [3] and [4]. We get this: [4] <-> [3] <-> [1] <-> [2]. If
the `Update::New*Chunk` for [4] doesn't contain a `previous`, the store
is out of sync: in the store, [4] has no previous, but [0] still has [1]
for its `next`.
With this `lazy_previous`, the links are correctly computed.
While implementing user verification on Element X I realized that the
`IdentityStatusChanges` stream does not notify us when an user becomes
`Verified`, which is a shame as it's perfect for powering app updates
after verifying users (i.e. all the decorations we show throughout the
app: room header, room details, room member list, room member profile
etc.)
Had a look at the existing code and, while that seems completely
intentional, there is no reason why we can't expand its purview.
This adds a task to compile the benchmarks in CI, without running them,
and with the lowest level of optimization that's available (the `dev`
profile).
As recommended by BCP 195.
It shouldn't be a problem with rustls that only supports TLS 1.2 and 1.3, but with native-tls it depends on the implementation.

This should be the most common case, and is already the only case
supported by the higher level APIs like `url_for_oidc` and
`login_with_qr_code`. It simplifies the API because we can call
`restore_registered_client` directly from `register_client`, which was a
TODO.

This patch adds and implements the
`EventCacheStore::filter_duplicated_events` method. It is implemented on
the `MemoryStore` and the `SqliteEventCacheStore`.
This method remove the unique events and reutrn the duplicated events.
This patch updates `RoomEventCache::subscribe` to be infallible. This
method wasn't able to return something else than an `Ok`. The return
type has been updated from `Result<T>` to `T`.
The `RoomEvents` doesn't hold the `Deduplicator` instance now, it's the
role of the `RoomEventCacheState`. This slightly simplifies the code, in
a few cases.
