Restart the IO scheduler if needed to make the new config value effective (for `MvboxMove,
OnlyFetchMvbox, SentboxWatch` currently). Also add `set_config_internal()` which doesn't affect
running the IO scheduler. The reason is that `Scheduler::start()` itself calls `set_config()`,
although not for the mentioned keys, but still, and also Rust complains about recursive async calls.
When a key is gossiped for the contact in a verified chat,
it is stored in the secondary verified key slot.
The messages are then encrypted to the secondary verified key
if they are also encrypted to the contact introducing this secondary key.
Chat-Group-Member-Added no longer updates the verified key.
Verified group recovery only relies on the secondary verified key.
When a message is received from a contact
signed with a secondary verified key,
secondary verified key replaces the primary verified key.
When verified key is changed for the contact
in response to receiving a message
signed with a secondary verified key,
"Setup changed" message is added
to the same chat where the message is received.
* Small performance improvement by not unnecessarily loading the peerstate
* Remove wrong info message "{contact} verified" when scanning a QR code with just an email
I think that this was a bug in the original C code and then slipped
through two refactorings.
This adds functionality to send and receive a backup over the network
using a QR code.
The sender or provider prepares the backup, sets up a server that
waits for clients. It provides a ticket in the form of a QR code
which contains connection and authentication information.
The receiver uses the QR code to connect to the provider and fetches
backup, restoring it locally.
This allows to distinguish exceptions,
such as database errors, from invalid user input.
For example, if the From: field of the message
does not look like an email address, the mail
should be ignored. But if there is a database
failure while writing a new contact for the address,
this error should be bubbled up.
