Create unprotected group in test_create_protected_grp_multidev
The test is renamed accordingly.
SystemMessage::ChatE2ee is added in encrypted groups
regardless of whether they are protected or not.
Previously new encrypted unprotected groups
had no message saying that messages are end-to-end encrypted
at all.
This mechanism replaces `Chat-Verified` header.
New parameter `_verified=1` in `Autocrypt-Gossip`
header marks that the sender has the gossiped key
verified.
Using `_verified=1` instead of `_verified`
because it is less likely to cause troubles
with existing Autocrypt header parsers.
This is also how https://www.rfc-editor.org/rfc/rfc2045
defines parameter syntax.
MX record lookup was only used to detect Google Workspace domains.
They can still be configured manually.
We anyway do not want to encourage creating new profiles
with Google Workspace as we don't have Gmail OAUTH2 token anymore
and new users can more easily onboard with a chatmail relay.
This allows to send send messages when disconnected
using `send_msg_sync` to create a dedicated connection
and send a single message.
The command can be used for measuring
the duration of SMTP connection establishment.
darwin.apple_sdk.frameworks is deprecated and does nothing according to
<https://nixos.org/manual/nixpkgs/stable/#sec-darwin-legacy-frameworks>
libiconv dependency also does not seem to be needed for `libdeltachat`,
I have checked that `nix build .#libdeltachat` still succeeds on macOS.
Before, the color was computed from the address, but as we've switched to fingerprint-based contact
colors, this logic became stale. Now `deltachat::contact::get_color()` is used. A test would be nice
to have, but as now all the logic is in Core, this isn't critical as there are Core tests at least.
Any control information from the message
should only be downloaded when the message
is fully downloaded to avoid processing it twice.
Besides, "partial" messages may actually be full messages
with an error that are only processed as partial
to add a message bubble allowing to download the message later.
In-Reply-To may refer to non-call message
as we do not control the sender.
It may also happen that call message
was received by older version and processed
as text, in which case correct In-Reply-To
appears to be referring to the text message.
Emitting an `AccountsItemChanged` event is needed for UIs to know when `Contact::get_color()` starts
returning the true color for `SELF`. Before, an address-based color was returned for a new account
which was changing to a fingerprint-based color e.g. on app restart. Now the self-color is our
favorite gray until own keypair is generated or imported e.g. via ASM.
