* Fix#2335 (delete job flooding)
The problem was:
- You are offline, and an ephemeral message is due to delete.
- load_imap_deletion_job() is called and returns a deletion job for it.
- The job fails because, well, we are offline.
- The job is saved into the database.
- load_imap_deletion_job() is called again, and so on.
* Add test
ct.name was insufficient, as authname, overridden name and email address
fallback were not taken into account.
Dropping this condition increases performance by 25% according to the
benchmark.
Also add a test for search_msgs.
It reduces the time by ~20% according to `search_msgs` benchmark.
Sorting by IDs is sufficient for global search as IDs increase in the
order of message reception.
the user-given contact name may be set to an empty string;
in this case the authname or the email is used for the contact
and also for the name of possibly existing chats.
this works well for `dc_chat_get_name()` as that just uses
`dc_contact_get_display_name()` for single-chats.
it did not work for `dc_get_chatlist(query)` as that
uses the database for performance reasons -
however, in the database, the empty string is written
instead of the display name is written for a chat.
this is fixed by this pr by also using
dc_contact_get_display_name() when updating the chats-table
(similar to `dc_create_chat_by_contact_id()`)

This patch adds seamless support for "Mixed Up" Encryption, repairing
mangled Autocrypt messages without notifying the user.
&str queries are not persistent by default. To make queries persistent,
they have to be constructed with sqlx::query.
Upstream sqlx does not contain the change that make all queries
persistent, but it is not needed anymore. but
fix #2073fix#2292 (I think)
- Messages can be assigned to any chat by the References and In-Reply-To, also to 1:1 chats; this has higher priority than the group id because with ad-hoc groups, it can happen that two devices have different group ids for the same conversation thread.
- If `From` is not in the chat (we call this "shadow sender"), `OverrideSenderDisplayname` is set. This communicates to the UI that:
- A `~`should be added in front of the sender's displayname.
- Also in 1:1 chats, the sender's displayname and avatar is shown, as if this was a group.
The "Unknown sender for this chat" messages are completely removed for unprotected groups.
For protected chats, everything stays as it was before.
POSTPONED:
- Maybe (if it turns out to be still necessary):
- The ad-hoc group id is computed by the the References, instead of the member list, as it is currently done
- How do we prevent that the message can't be assigned to the correct chat as the parent message was deleted?
Switches from rusqlite to sqlx to have a fully async based interface
to sqlite.

fix#2188
Also, if we notice that the server started reusing old UIDs, _also_ do a `ResyncFolders`, because the server likely forgot to change uid_validity
save subject for messages:
- new api `dc_msg_get_subject()`,
- when quoting, use the subject of the quoted message as the new subject, instead of the
last subject in the chat
