804bd221b2 crypto: Improve key imports. 
This patch changes so key imports load all existing sessions at once
instead loading a single session for each session we are importing. It
removes the need to lock the session when we check the first known index
and exposes the total number of sessions the key export contained.

5d0ff961b2 crypto: Check the Olm message hash if we fail to decrypt an Olm message. 
Wether by accident (the next_batch token doesn't get stored properly) or
by malicious intent (the server replays a message) an Olm encrypted to-device
message may appear multiple times.

This is usually fine since nothing bad happens, we don't decrypt the message
and the message gets thrown away.

Since the introduction of Olm session unwedging an undecryptable message
leads to the creation of a new fresh Olm session. To avoid this we
remember which Olm messages we already decrypted so they don't trigger
an unwedging dance.

7cab7cadc9 crypto: Rework the cryptostore. 
This modifies the cryptostore and storage logic in two ways:
    * The cryptostore trait has only one main save method.
    * The receive_sync method tries to save all the objects in one
    `save_changes()` call.

This means that all the changes a sync makes get commited to the store
in one transaction, leaving us in a consistent state.

This also means that we can pass the Changes struct the receive sync
method collects to our caller if the caller wishes to store the room
state and crypto state changes in a single transaction.
