This method will retrieve the database sizes if available and expose it in the client.
Note: the actual database size measuring is only implemented for the SQLite based stores
This patch removes some logs around the cross-process lock methods. This
is called pretty often by the cross-process lock task, which pollute the
log files.
The supported versions are necessary for querying almost all endpoints,
but after homeserver auto-discovery the well-known info is only
necessary to get the MatrixRTC foci advertised by the homeserver. So it
shouldn't be necessary to always request both at the same time.
Besides:
- Not all clients support MatrixRTC, so they don't need the well-known
info.
- The well-known info is only supposed to be used for homeserver
auto-discovery before login. In fact, the MatrixRTC MSC was changed to
use a new endpoint for this.
- We don't have access to the server name after restoring the Client, so
the well-known lookup is more likely to fail.

This patch removes the `connection::Config` type. It was “inspired”
from `deadpool_sqlite`, but we can clearly remove it by using our own
`SqliteStoreConfig` type. It simplifies the way we open a database.
This patch replaces `deadpool-sqlite` by our own implementation in
`crate::connection`. It still uses `deadpool` but the object manager has
a different implementation.
This patch adds `CrossProcessLockGeneration`. A lock generation is an
integer incremented each time the lock is taken by another holder. If
the generation changes, it means the lock is _dirtied_. This _dirtying_
aspect is going to be expanded in the next patches. This patch focuses
on the introduction of this _generation_.
The `CrossProcessLock::try_lock_once` method, and
the `TryLock::try_lock` method, both returns a
`Option<CrossProcessLockGeneration>` instead of a `bool`: `true` is
replaced by `Some(_)`, `false` by `None`.
This patch introduces a write-only connection in `SqliteStateStore`
_à la_ `SqliteEventCacheStore`. The idea is to get many read-only
connections, and a single write-only connections behind a lock, so that
there is a single writer at a time.
This patch renames the `acquire` method to `read`, and it introduces a
new `write` connection.
