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.
`OutPreparing` is deprecated since 2024-12-07, replace it with `OutFailed`, such messages are
probably not interesting anymore. `OutMdnRcvd` is not used in the db for new messages since
a30c6ae1f7, `OutDelivered` is stored instead.
This avoids creating 1:1 chat on a second device when joining a channel.
Now when joining a channel there may be no 1:1 chat with the inviter
when the channel is created. In this case we still create the channel
as unblocked even if 1:1 chat would be a contact request
because joining the channel is an explicit action
and it is not possible to add someone who did not scan a QR
to the channel manually.

`test_import_encrypted_bak_into_encrypted_acct` CFFI test fails because
it tests that trying to import an encrypted account with a wrong
passphrase into an already-encrypted database will fail, but leave the
already-encrypted database (esp, leave it with the same password).
But in order to reset the database after a failed login attempt, I'm
using this code:
```rust
context.sql.close().await;
fs::remove_file(context.sql.dbfile.as_path())
.await
.log_err(context)
.ok();
context
.sql
.open(context, "".to_string()) // <-- NOTE THIS LINE
.await
.log_err(context)
.ok();
```
We're not remembering the password, so, we can't just pass the correct
password there.
Since password-protected databases are not really supported anyways, we
decided to just skip the test.
I also tried two tricks for deleting everything [found on
Stackoverflow](https://stackoverflow.com/questions/525512/drop-all-tables-command),
but neither of them managed to actually reset the database (i.e. they
led to a failed Rust test, because asserting
`!context2.is_configured().await?` failed):
```rust
context
.sql
.call_write(|conn| {
let mut stmt = conn.prepare(
"select 'drop table ' || name || ';' from sqlite_master where type = 'table';",
)?;
let mut iter = stmt.query(())?;
while iter.next()?.is_some() {}
Ok(())
})
.await
.log_err(context)
.ok();
context
.sql
.run_migrations(context)
.await
.log_err(context)
.ok();
```
```rust
context
.sql
.transaction(|t| {
t.execute_batch(
"
PRAGMA writable_schema = 1;
delete from sqlite_master where type in ('table', 'index', 'trigger');
PRAGMA writable_schema = 0",
)?;
Ok(())
})
.await
.log_err(context)
.ok();
context
.sql
.run_migrations(context)
.await
.log_err(context)
.ok();
```

this PR cleans up with some easy, deprecated stuff.
i roughly checked that they are no longer in use - by these checks,
other deprecated function were kept, eg.
dc_provider_new_from_email_with_dns() and dc_chat_is_protected() is
still used by deltatouch - to not add noise there, we remove them here
on the next cleanup ...
for DC_STR_*, however, if they are in used, the corresponding lines
should just be removed
this will cleanup https://c.delta.chat/deprecated.html as well
All users of this function expect a nonempty list to be returned, otherwise they fail with hard to
understand errors like "No connection attempts were made", so it's better to fail early if DNS
resolution failed and the cache doesn't contain resolutions as well.
