Sticky encryption rule, requiring that all replies to encrypted messages
are encrypted, applies only to messages with a quote now.

This code is inconsistent with EncryptHelper::should_encrypt, which uses
quorum rule.
UI does not display or use encryption state in-between preparing and
sending message anyway.
In addition, "sticky encryption" rule, which required all replies to
encrypted messages to be encrypted, is dropped. It is going to be
restored with the introduction of quoting.
both are not used in productive:
- chat-id "in-creation" was dropped completely already in core-c
as it does not allow assigning messages to chats in time.
- message flag "starred" was added at some point and never used.
ux-wise, "disappearing messages" promises to clean up a chat -
this does not fit well with "starring" messages.
"saved messages" chat seems to be superior in that regard.
but anyway, it is not used but comes at maintainance costs,
so it is better to delete its functionality for now.
(the db entries, however, are left for now,
that might be more tricky to remove)
Address is used to generate Message-Id.
Previously error toast was shown, but MsgId was returned from
chat::prepare_msg anyway. Now chat::prepare_msg returns an error.
error!() is removed, because FFI library shows errors via
.unwrap_or_log_default().
When run against host that is not in the provider database or has multiple
IMAP servers listed, this test fails because one error is returned for
each server.
* Mention in dc_event_get_data2_str method that it can also return 0
* Update deltachat-ffi/deltachat.h

Previously, standard Autocrypt rule was used to determine whether
encryption is enabled: if at least one recipient does not prefer
encryption, encryption is disabled.
This rule has been problematic in large groups, because the larger
is the group, the higher is the chance that one of the users does not
prefer encryption.
New rule requires a majority of users to prefer encryption. Note that it
does not affect 1:1 chats, because it is required that *strictly* more
than a half users in a chat prefer encryption.
partly, we wrote '@return None.' for void functions,
however, some linter complain about that (recently swift)
and they're right, it does not make much sense.
