This patch implements `LatestEvent::update_with_send_queue`.
It introduces an intermediate type, for the sake of clarity,
`LatestEventValuesForLocalEvents`.
The difficulty here is to keep a buffer of `LatestEventValue`s requested
by the `SendQueue`. Why? Because we want the latest event value, but we
only receive `RoomSendQueueUpdate`s, we can't iterate over local events
in the `SendQueue` like we do for the `EventCache` to re-compute the
latest event if a local event has been cancelled or updated.
A particular care must also be applied when a local event is wedged:
this local event and all its followings must be marked as wedged too,
so that the `LatestEventValue` is `LocalIsWedged`. Same when the local
event is unwedged.
This patch splits the `LatestEventValue` type into `LatestEventValue`
+ `LatestEventKind`. Basically, all variants in `LatestEventValue` are
moved inside the new `LatestEventKind` enum. `LatestEventValue` keeps
`None`, and see the new `Remote`, `LocalIsSending` and `LocalIsWedged`
variants.
This patch also extracts the message-like handling of `find_and_map`
(now renamed `find_and_map_timeline_event`) into its own function:
`find_and_map_any_message_like_event_content`. This is going to be
handful for the send queue part.
This patch updates `compute_latest_events` to broadcast a
`RoomSendQueueUpdate` onto `LatestEvent`. It introduces the new
`update_with_send_queue` method.
This patch renames the `update` methods to `update_with_event_cache`
in the `latest_events` module. It frees the road to introduce
`update_with_send_queue`.
This patch updates `LatestEvents` to listen to the updates from the
`SendQueue`. The `listen_to_event_cache_and_send_queue_updates` function
contains the important change. A new `LatestEventQueueUpdate` enum is
added to represent either an update from the event cache, or from the
send queue.
So far, `compute_latest_events` does nothing in particular, apart from
panicking with a `todo!()` when a send queue update is met.
Allows `Backups::maybe_download_room_key` to accept any T:
JsonCastable<EncryptedEvent>, which will be required for state events to
trigger fetching the room key.
Implements JsonCastable<EncryptedEvent> for
OriginalSyncStateRoomEncryptedEventContent.
Implements JsonCastable<AnyStateEvent> for RoomEncryptedEventContent.
Modifies `OlmMachine::decrypt_room_event_inner` to call a new method
`OlmMachine::verify_packed_state_key` which, if the event is a state
event, verifies that the original event's state key, when unpacked,
matches the state key and event type in the decrypted event content.
Introduces MegolmError::StateKeyVerificationFailed and
UnableToDecryptReason::StateKeyVerificationFailed which are thrown when
the verification fails.

This commit also refactors out what would be common code between
::encrypt and ::encrypt_state to a helper ::encrypt_inner.

When a room is joined, a corresponding index is created.
When a message is received via sync or via a back-pagination, it is
added to the corresponding room's index.
