This patch uses a new `async-once-cell` crate to make `Room::timeline`
and `Room::sneaky_timeline` by making them lazy. Their values are
computed lazily, on-demand, when calling the `Room::timeline` method or
`Room::latest_event`.
This extension was enabled by both ElementX apps by default, along with the e2ee / to-device extensions that will be handled
by the new Notification API. To maintain the current behavior, it's important to re-enable this extension before getting
RoomList in production.

* sliding sync: infer the storage key from the loop id and user id
* chore: rename `sync_id` to `id`
* chore: check that the sliding sync id is less than 16 chars
* chore: rejigger the storage key creation logic
Now the prefix is visible only in the `format_storage_key_prefix` function, and other `format_storage_key` function will be based off that.
* chore: update sliding sync README with API updates and fix outdated information
* chore: clippy + fix test

This patch handles errors from the Sliding Sync loop properly.
When an error is received, the `RoomList` state machine enters the
`Terminated` state. Immediately after that, the sync stream is stopped.
When the sync stream is restarted, the next state will be calculated.
When the current state is `Terminated`, the next state is the state
that led to the `Terminated` state. To avoid having a “first” huge sync
(imagine a room list of 1000 rooms, you don't want to “resume” from an
error with a first sync for 1000 rooms), lists are partially “reset”
depending of the state where the machine is in.
An important test has been added to test all possibles cases with errors
and list' states.
First off, `SlidingSync::sync_once` no longer returns
`Option<UpdateSummary>` but `UpdateSummary`. It simplifies the rest of
the patch.
Next, `SlidingSync::sync` returns either `Ok(…)` and continues to sync,
or it returns `Err(…)` and it stops the sync stream immediately. No more
error could be returned with the stream to continue syncing.
Finally, the `UnknownPos` error no longer emits an err, but silently
skip over the sync-loop until the threshold is reached; which in this
case will generate a proper error.
This patch changes `RoomInner` to have an `room:
Option<matrix_sdk::room::Room>` field to `room: matrix_sdk::room::Room`.
`room` is not longer an `Option`.
Then, it's easier to have a new `timeline: Timeline` field, along with a
`sneaky_timeline: Timeline` field. Both are used by the new
`Room::timeline()` and `Room::latest_event()` method.
This patch implements `RoomList::room`, which returns a `Result<Room>`:
the room ay or may not exist.
A new `Room` type is created. It wraps an `Arc<RoomInner>` type, so that
it's cheap to clone it.
The `RoomInner` type owns a `SlidingSyncRoom` and
`matrix_sdk::room::Room` type. If some API or data are missing on
the former, the latter acts as a backup. This is the case for the
`Room::name` method which makes it best to return a name to the caller.
This patch lands the first design of the `Input` API. An `Input` is
something external that can be understood by the `RoomList` state
machine. The first inpuput is `Viewport` to change the “viewport” of the
`RoomList`, which translates to the change of the ranges of one specific
Sliding Sync list.
This patch implements `RoomList::update_entries_stream_filter` which
allows to… change the… entries stream filter. This patch also provides a
test for that. How nice it is.
