Don't show a contact as verified if their key changed in the meantime
If a contact's key changed since the verification, then it's very
unlikely that they still have the old, verified key. So, don't show them
as verified anymore.
This also means that you can't add a contact like this to a verified
group, which is good.
The documentation actually already described this (new) behavior:
```rust
/// and if the key has not changed since this verification.
```
so, this adapts the code to the documentation.
This commit adds new stock strings
"I added member ...",
"I removed member ..." and
"I left the group" that are sent over the network
and are visible in classic MUAs like Thunderbird.
Member name in these messages uses authname
instead of the display name,
so the name set locally does not get leaked when
a member is added or removed.
* 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.
Moved custom ToSql trait including Send + Sync from lib.rs to sql.rs.
Replaced most params! and paramsv! macro usage with tuples.
Replaced paramsv! and params_iterv! with params_slice!,
because there is no need to construct a vector.
To handle backups the UIs have to make sure they do stop the IO
scheduler and also don't accidentally restart it while working on it.
Since they have to call start_io from a bunch of locations this can be
a bit difficult to manage.
This introduces a mechanism for the core to pause IO for some time,
which is used by the imex function. It interacts well with other
calls to dc_start_io() and dc_stop_io() making sure that when resumed
the scheduler will be running or not as the latest calls to them.
This was a little more invasive then hoped due to the scheduler. The
additional abstraction of the scheduler on the context seems a nice
improvement though.
It seems .abort() does not work on the recently seen loop
in some cases, e.g. if it is busy looping in a separate thread.
In my case after account reconfiguration recently seen loop
kept running and issuing warnings about closed interrupt channel.
Exit from recently seen loop on errors to avoid using 100% CPU
in such cases.
Derive Debug, PartialEq and Eq for Peerstate,
so `verifier` is included in Debug output and compared.
Store verifier as empty string
instead of NULL in the database.
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.
* Because both only make problems with mailing lists, it's easiest to just disable them. If we want, we can make them work properly with mailing lists one day and re-enable them, but this needs some further thoughts.
Part of #3701
* Use load_from_db() in more tests
* clippy
* Changelog
* Downgrade warning to info, improve message
* Use lifetimes instead of cloning
* allow deleting referenced contacts in UI
we are quite often getting requests of users
who want to get rid of some contact in the "new chat" list.
there is already a "delete" option,
but it does not work for referenced contacts -
however, it is not obvious for users that a contact is in use,
esp. of some mailing list or larger chat, old contacts, whatever.
this pr revives an old idea [^1] of "soft deleting" referenced contacts -
this way, the user can remove the annoying entry
without the need to understand complicated things
and finally saying that deletion is impossible :)
once the contact is reused, it will reappear,
however, this is already explained in the confirmation dialog of the UIs.
technically, this pr was simpler as expected as we already have
a Origin::Hidden, that is just reused here.

* update rust doccomment
* update changelog
* avoid races on contact deletion
chats may be created between checking for "no chats" and contact deletion.
this is prevented by putting the statement into an EXCLUSIVE transaction.
* fix failing python test
Very small PR; Motivation: Easier navigation using Go-To-definition.
Because, using go-to-definition of rust-analyzer on parse() doesn't take you to the actual parse() implementation but its trait definiton. On the other hand, it's very easy to find EmailAddress::new().
