Removing a relay now takes effect immediately:
- the profile stops fetching and advertising it,
- secondary devices immediately apply the removal through the transport sync,
Upgrading removes unpublished relays and triggers keyupdates.
BREAKING CHANGE: set_transport_unpublished() is removed: UIs call delete_transport() when the user removes a relay.
BREAKING CHANGE: list_transports_ex() and the TransportListEntry type are removed: use list_transports().
BREAKING CHANGE: delete_transport() no longer refuses to remove the primary transport: it refuses only to remove the last one and re-elects the sending transport as needed.
BREAKING CHANGE: TransportsModified is now also emitted on the device modifying the transports, not only on devices applying the synced change.
Deprecated: DC_STR_PHASING_OUT
When the published relay list changes, key-contacts are informed with an
unsigned message carrying the re-signed key, encrypted to a chunk of contacts
at a time. It is shaped like a receipt notification naming no message, so that
cores which know nothing about keyupdates trash it as well.
See the src/keyupdate.rs module docs for the design.
Requests now register before testing for shutdown,
so either the reader loop or the caller answers them.
Also failed start() winds down its threads, ignoring a broken pipe on stdin.
Adds following stock strings:
- You were removed by %1$s.
- You were added by %1$s.
and implicit equivalents:
- You were removed.
- You were added.

previously only 10 messages were sent but if joinining did not succeed (due to slow CI sometimes) nothing would be received and the test would hang.
Also cleans up the tests to not set webxdc realtime config (true by default) and restructure helpers to reduce redundant code.
Devices no longer implicitely use the From address of sync messages
to determine their primary transport. Receivers have no concept of it and own devices
may disagree on which relay is reachable because of VPN or different networks:
1. Make setting a primary transport (`configured_addr`) a per-device non-synced operation.
2. Transport rows (add/remove/unpublish) keep syncing like before.
3. A device reelects a primary if a sync message unpublished/removed the current primary
if there is a better candidate.
4. `TransportsModified` event is emitted at most once on an incoming transport sync message.
Users will notice the change in that changing primary transport in settings/advanced/relays
will not synchronize to other devices anymore.
Unifies internal naming of single/direct/1:1/normal chats
to match the naming used in the API.

Alternative to https://github.com/chatmail/core/pull/8355/, fixes
https://github.com/chatmail/core/issues/8329
This fixes the following bug:
Scanning QR for existing contact doesn't update relay list
Two chat partners suddenly lost connectivity to all of their relays. They added another relay, which is accessible, and set it as main. Of course, they still couldn't communicate, because there was no way to announce a new relay list to each other (clients know only about old relays so they try to send updates there).
That's why the friends used a different channel (e.g. met IRL) to send their QR codes once again.
Expected behavior: They would expect that clients update their relay lists according to the contact info inside the QR codes, and they can continue talking in Delta.
Actual behavior: But Delta Chat client doesn't update a list of announced relays on scanning a QR in case a contact already exists. It simply opens the existing chat without altering any contact info.

Fix https://github.com/chatmail/core/issues/8195
Supersedes https://github.com/chatmail/core/pull/8217
The most interesting change is in `delete_expired_imap_messages()`
because there, messages are marked for deletion on single-device
chatmail profiles.
The logic in `delete_expired_imap_messages()` was wrong before, and
pre-messages were not deleted at all. This is fixed by also querying
`pre_rfc724_mid` in addition to `rfc724_mid` from the `msgs` table.
In order not to make the SQL statement too complex, I split it into two.
WRT tests:
- `test_immediate_autodelete()` tests the auto-deletion;
`test_imap_autodelete_fully_downloaded_msg()` tests that even for a
message that is split into pre- and post-message, both messages are
deleted.
- A lot of tests test that if bcc_self is on, messages are not
auto-deleted. E.g. `test_one_account_send_bcc_setting()` and
`test_markseen_message_and_mdn()` relies on the fact that messages stay
on the server when bcc_self is on.
- Unfortunately, it is not possible to test that messages are only
deleted for chatmail servers, because we don't have any tests that use a
non-chatmail server.
Messages are iterated over in fetch_new_msg_batch()
and largest_uid_fetched variable is updated there
assuming that messages come in the order of increasing UID.
If UIDs are not increasing, it is possible
that largest_uid_fetched will be updated
even though smaller UID is not fetched yet
and the message will be lost.
INTERNALDATE sorting was introduced to
deal with email providers such as Gmail
that keep INTERNALDATE but not the UID
order when moving the messages.
Since we don't move the messages anymore
after commit 04c0e7da16,
there is no need for ordering by INTERNALDATE.
We don't want to send an outgoing message from the 2nd device (`ac1_clone`) before receiving the
incoming one and expect that the messages will be ordered correctly on the 1st device (`ac1`). Let's
ensure the correct message order locally in the first place. I checked logs of a failed test run and
it indeed happened that `ac1_clone` sent the message earlier, so it can't reference the incoming
message and `tweak_sort_timestamp()` does nothing on `ac1`, so the messages can't be ordered
correctly considering that smeared clocks on the devices are diferent.
I assume that the problem was that sometimes, alice2 or fiona doesn't
accept alice's smeared timestamp, because `calc_sort_timestamp()`
doesn't allow the timestamp of a received message to be in the future. I
tried this patch:

// get newest message for this chat
```
...maybe this patch makes sense anyways, but you still get the problem
that the message sent by alice2 (i.e. the add-fiona message) will have
an earlier timestamp than the message sent by alice, because alice
already sent more messages, and therefore has more timesmearing-seconds.
It's unsure it makes sense to modify calc_sort_timestamp() this way because if some chat member has the clock in the future (even unintentionally), their fresh messages will be sorted to the bottom relatively to others' fresh messages. Maybe it's even better to limit the message timestamp ("Date") by the current system time there.
To really fix the problem, we could send a serial number together with the timestamp, that distinguishes two messages sent in the same second. But since we haven't gotten complaints about message ordering since some time, let's just leave things as they are.
Since all this timesmearing is a bit best-effort right now, I decided to
instead just make the test more relaxed.
Rpc.start() now calls get_system_info() after launching the server
to verify it started successfully. If the server exits early (e.g.
due to an invalid accounts directory), the core error message from
stderr is captured and included in the raised JsonRpcError.
The reader_loop now unblocks pending RPC requests when the server
closes stdout, so callers never hang on a dead server.
Export JsonRpcError from the deltachat_rpc_client package.
Add test_early_failure verifying that Rpc.start() raises with
the actual core error message for invalid accounts directories.
Timestamp renewal was introduced in 1dbf924c6a "feat:
chat::resend_msgs: Guarantee strictly increasing time in the Date header" so that re-sent messages
can be deduplicated on the reciver side, but the deduplication logic doesn't depend on "Date"
anymore.
Iroh-Gossip-Topic is sent in a post-message. Post-message goes to trash,
so topic should be associated with the existing pre-message that is
updated rather than with the post-message.
Fix https://github.com/chatmail/core/issues/7835.
The problem was most probably:
- `ac1_clone` receives the sync message, sends `TRANSPORTS_MODIFIED`
event, and launches a task that will restart IO
- After IO was stopped, but before it is started again,
`ac1_clone.add_transport_from_qr(qr)` is called
- this check fails:
```rust
ensure!(
!self.scheduler.is_running().await,
"cannot configure, already running"
);
```
Existing test relies on folder scanning.
We are going to remove the option to not show emails
(<https://github.com/chatmail/core/issues/7631>)
so the test will be removed eventually anyway.
