feat: Make broadcast lists create their own chat - UIs need to ask for
the name when creating broadcast lists now (see
https://github.com/deltachat/deltachat-android/pull/2653)
That's quite a minimal approach: Add a List-ID header to outgoing
broadcast lists, so that the receiving Delta Chat shows them as a
separate chat, as talked about with @r10s and @hpk42.
Done:
- [x] Fix an existing bug that the chat name isn't updated when the
broadcast/mailing list name changes (I already started this locally)
To be done in other PRs:
- [ ] Right now the receiving side shows "Mailing list" in the subtitle
of such a chat, it would be nicer if it showed "Broadcast list" (or
alternatively, rename "Broadcast list" to "Mailing list", too)
- [ ] The UIs should probably ask for a name before creating the
broadcast list, since it will actually be sent over the wire. (Android

BREAKING CHANGE: This means that UIs need to ask for the name when creating a broadcast list, similar to https://github.com/deltachat/deltachat-android/pull/2653.
This is needed to test periodic re-gossiping in existing chats.
Also add a test for verified groups on that even if "member added" message is missed by a device of
newly added member, after re-gossiping Autocrypt keys to the group it successfully learns these keys
and marks other members as verified.
Previously it was required that a directory path is provided to the import API.
Now it is possible to point directly to the .asc file containing a secret key.
This allows UI to present a file selection dialog to the user
and let select the file directly.
Selecting a directory is still supported for backwards compatibility.
It can be used e.g. as a default in the file saving dialog. Also display the original filename in
the message info. For these purposes add Param::Filename in addition to Param::File and use it as an
attachment filename in sent emails.
Opening the same account (context) from multiple processes is dangerous, can result in duplicate
downloads of the same message etc. Same for account manager, attempts to modify the same
accounts.toml even if done atomically with may result in corrupted files as atomic replacement
procedure does not expect that multiple processes may write to the same temporary file.
accounts.toml cannot be used as a lockfile because it is replaced during atomic update. Therefore, a
new file next to accounts.toml is needed to prevent starting second account manager in the same
directory.
But iOS needs to be able to open accounts from multiple processes at the same time. This is required
as the "share-to-DC extension" is a separate process by iOS design -- this process may or may not be
started while the main app is running. Accounts are not altered however by this extension, so let's
add to the `Accounts::new()` constructor an `rdwr` parameter which allows to read the accounts
config w/o locking the lockfile.
