This patch extracts fields from `RoomEventCacheState` and move them
into `RoomEventCacheStateLock`. This lock provides 2 methods: `read`
and `write`, respectively to acquire a read-only lock, and a write-only
lock, represented by the `RoomEventCacheStateLockReadGuard` and the
`RoomEventCacheStateLockWriteGuard` types.
All “public” methods on `RoomEventCacheState` now are facade to the read
and write guards.
This refactoring makes the code to compile with the last change in
`EventCacheStore::lock`, which now returns a `EventCacheStoreLockState`.
The next step is to re-load `RoomEventCacheStateLock` when the lock is
dirty! But before doing that, we need this new mechanism to centralise
the management of the store lock.
This allows custom message-like events (created by the `EventContent` macro from ruma) to be added to the timeline if they are explicitly allowed when building the timeline with a custom `event_filter`.
The custom event content is not available directly to the consumer, but it can still fetch it from the matrix-sdk client with its `event_id`, or display a "this type of event is not supported".

Fixes#5598.
This patch improves throughput by +710% in `room_list_service` sorters
and filters. It introduces a new `room_list_service::Room` type that
derefs to `matrix_sdk::Room`. However, it **caches** some data from
`matrix_sdk::Room`. Why doing so? Because filters, but more specifically
sorters!, are calling methods on `matrix_sdk::Room`, so likely on
`matrix_sdk::RoomInfo`, quite intensively. `RoomInfo` is behind a
`SharedObservable`, which means it's behind a lock. Each time a sorter
sorts 2 rooms, the lock on `RoomInfo` can be called twice or more.
By caching the data, `RoomInfo` is reached once per refresh data, but
not during the filtering nor the sorting. It greatly reduces contention
on the `RoomInfo` lock, which improves the throughput by +710%, and the
time by -87%.
The cached data are refreshed in `merge_stream_and_receiver` when
(i) the stream of `Room` is updated, or when (ii) the stream of
`RoomInfoNotableUpdate` is updated. It's a central place it happens,
which isolates the behaviour.
This ensures that we're using the same color despite what your color
scheme of your terminal is. Some color schemes might produce unreadable
combinations of foreground color and background color.
This patch updates `RoomListService::subscribe_to_rooms` to call
`LatestEvents::listen_to_room` automatically. This method becomes async,
which propagates to a couple of callers.
The idea is that when one is interested by a specific room, a
subscription will be applied. This is an opportunity to also “activate”
the computation of the `LatestEvent` for this specific room, so that the
user doesn't have to do that manually (except if room subscription is
never used).
This patch simplifies the selected read receipt rendering by the fact
that we can simply fetch the selected timeline item instead of the event
ID and then do a search for the selected item.
