* 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.

This makes the contact ID its own newtype instead of being a plain
u32. The change purposefully does not yet try and reap any benefits
from this yet, instead aiming for a boring change that's easy to
review. Only exception is the ToSql/FromSql as not doing that yet
would also have created churn in the database code and it is easier to
go straight for the right solution here.
- Replace .ok_or_else() and .map_err() with anyhow::Context where possible.
- Use .context() to check Option for None when it's an error
- Resultify Chatlist.get_chat_id()
- Add useful .context() to some errors
- IMAP error handling cleanup
* add basic multi-device-sync functions
* generate json
* add context.parse_sync_items()
* add context.execute_sync_items()
* piggyback sync-commands message, add body for human-readable part
* avoid double json renderings
* mimeparser parses incoming .json sync-files
* do not piggyback sync-files
* execute sync items
* return status of send_sync_msg()
* send sync messages as multipart/report
* add a per-item-timestamp and also allow adding other per-item-fields in the future
* if the self-chat does not exist, create it blocked/hidden
* create tokens closer to real qr-code needs
* respect bcc_self setting, add test for that
* sync qr code tokens after promoting groups
* send sync-messages only if an experimental switch is set
* trigger send_sync_msg() after sending messages and after creating/redraw/revive qr-code
* add DC_STR_* constants to deltachat.h
* adapt to refactored qr module as of #2729
* tweak test
* use SendSyncMsgs config name instead of SendExperimentalSyncMsgs - we can remove or rename the config nevertheless, but have the option to keep it without renaming
* tweak docs
* remove currently unused effective timestamp calculation
* clarify when send_sync_msg() is called
* make sure, sync-messages are encrypted and are sent by SELF
* tweak docs, fix typos
