This patch changes the capacity of the internal buffer of
`ObservableVector` for `SlidingSyncList::room_list` from 16 to 4096.
With an increased capacity, we reduce the probability to send a
`VectorDiff::Reset` to subscribers. `Reset` are happening quite often
for apps using `matrix-sdk`, and it impacts their performance. This
patch tries to improve this situation. This `room-list` contains
`RoomListEntry`, which is can cheap in terms of memory, compared to the
impact of sending `Reset`s too often. That's a tradeoff.
* bindings: Ignore silently malformed userId in migration of tracked users
* Clean: collect will now never fail

* crypto: implement more primitives for the MemoryStore to work in tests
* crypto: change the shape of the `CryptoStoreLock` API
In particular:
- make the lock work across multiple threads of the same process trying to acquire it,
using `num_holders`.
- add a mechanism to get the lock only once (for the NSE process, in case the main app
had acquired the lock before).
* client: add a cross-process crypto store lock, enable it with `Encryption::enable_cross_process_store_lock`
* client: make `preshare_room_key` a critical section of the cross-process lock
* sliding sync: make it possible to define different timeouts for a `SlidingSyncInstance`
This will be handy for the NSE process on iOS, which has very little time to wait for the proxy's responses.
* feat: implement the `EncryptionSync` API (renamed from `Notification` API)
* fixup! client: add a cross-process crypto store lock, enable it with `Encryption::enable_cross_process_store_lock`
* feat: allow disabling e2ee / to-device in the RoomList API
* feat: use same SS id for main/NSE process, reload to-device token from disk before each encryption sync
* fix: better error handling if restoring the to-device token failed
* feat: add logs for the locking functions
* test: add a few tests for encryption sync
* feat: add `reload_caches` method in the `EncryptionSync` + FFI bindings
* chore: clean up FFI loop
* encryption sync: Remove unused errors, specialize some errors
* feat: include termination reason in the encryption sync loop
* feat: add more logs
* chore: fmt + clippy + doc
* comment: precise only in the presence of another process
* Tweak `room_list` APIs to include `_with_encryption` variants
* chore: rustfmt
This patch moves `RoomListService::entries` and `::filtered_entries`
inside `RoomList`. It also implements `RoomList::new`. Finally,
it implements `RoomListService::all_rooms` and re-implement
`RoomListService::invites`.
Basically:
```rust
// 1.
room_list.entries().await?
// 2.
room_list.invites().await?
```
becomes:
```rust
// 1.
room_list.all_rooms().await?.entries()
// 2.
room_list.invites().await?.entries()
```
`all_rooms` and `invites` both return a `RoomList`.
