When there are no parent references,
Delta Chat inserts Message-ID into References.
Such references should be ignored
because otherwise fully downloaded message
may be assigned to the same chat as previously incorrectly assigned
partially downloaded message.
Fixes receive_imf::tests::test_create_group_with_big_msg
Chat-Group-ID always correctly identifies the chat
message was sent to, while In-Reply-To and References
may point to a message that has itself been incorrectly
assigned to a chat.
This protects Bob (the joiner) of sending unexpected-unencrypted messages during an otherwise nicely
running SecureJoin.
If things get stuck, however, we do not want to block communication -- the chat is just
opportunistic as usual, but that needs to be communicated:
1. If Bob's chat with Alice is `Unprotected` and a SecureJoin is started, then add info-message
"Establishing guaranteed end-to-end encryption, please wait..." and let `Chat::can_send()` return
`false`.
2. Once the info-message "Messages are guaranteed to be e2ee from now on" is added, let
`Chat::can_send()` return `true`.
3. If after SECUREJOIN_WAIT_TIMEOUT seconds `2.` did not happen, add another info-message "Could not
yet establish guaranteed end-to-end encryption but you may already send a message" and also let
`Chat::can_send()` return `true`.
Both `2.` and `3.` require the event `ChatModified` being sent out so that UI pick up the change wrt
`Chat::can_send()` (this is the same way how groups become updated wrt `can_send()` changes).
SECUREJOIN_WAIT_TIMEOUT should be 10-20 seconds so that we are reasonably sure that the app remains
active and receiving also on mobile devices. If the app is killed during this time then we may need
to do step 3 for any pending Bob-join chats (right now, Bob can only join one chat at a time).
`ChatId::lookup_by_contact()` returns `None` for blocked chats, so it should be only used if we need
to filter out blocked chats, e.g. when building a chatlist.
E.g. the multi-device synchronisation creates the "Saved Messages" chat as blocked, in this case the
chat icon wasn't updated before and the user avatar was displayed instead.
this PR checks if the quotes are used in a reasonable way:
- quoted messages should be send to the same chat
- or to one-to-one chats
if the quote's chat ID is not the same than the sending chat _and_ the
sending chat is not a one-to-one chat, sending is aborted.
usually, the UIs does not allow quoting in other ways, so, this check is
only a "last defence line" to avoid leaking data in case the UI has
bugs, as recently in
https://github.com/deltachat/deltachat-android/issues/3032
@iequidoo @link2xt @adbenitez i am not 100% sure about this PR, maybe
i've overseen a reasonable usecase where other quotes make sense

Otherwise, e.g. if a message is a large GIF, but its viewtype is set to `Image` by the app, this GIF
will be recoded to JPEG to reduce its size. GIFs and other special viewtypes must be always detected
and sent as is.
