ade39fe026 fix: do not set WantsMdn param for outgoing messages
This bug sometimes results in sending read receipts to self in
multi-device setups.

It happens consistently in a setup where the first device is
configured to move messages to DeltaChat folder and the second device
is not. When both devices receive BCC-self message simultaneously, the
first device moves the message to DeltaChat folder, while the second
device tries to mark the message as seen in the Inbox. Regardless of
whether the second device marks the message as seen successfully or
fails because the message is already moved by the first device,
`Job.markseen_msg_on_imap()` sends the read receipt to the From
address.

20bf41b4e6 Set timestamps for system messages
Previously system messages were always added to the end of the chat,
even if the message triggering them was sent earlier.  This is
especially important for messages about disappearing timer reset
triggered by classic email messages, as they should be placed right
after the message resetting the timer.

065b574d93 Remove deaddrop chat
Contact request chats are not merged into a single virtual "deaddrop"
chat anymore. Instead, they are shown in the chatlist the same way as
other chats, but sending of messages to them is not allowed and MDNs
are not sent automatically until the chat is "accepted" by the user.

New API:
- dc_chat_is_contact_request(): returns true if chat is a contact
request.  In this case option to accept and block the chat via
dc_accept_chat() and dc_block_chat() should be shown in the UI.
- dc_accept_chat(): accept contact request and unblock the chat
- dc_block_chat(): decline contact request and block the chat

Removed API:
- dc_create_chat_by_msg_id(): deprecated 2021-02-07 in favor of
  dc_decide_on_contact_request()
- dc_marknoticed_contact(): deprecated 2021-02-07 in favor of
  dc_decide_on_contact_request()
- dc_decide_on_contact_request(): this call requires a message ID from
  deaddrop chat as input. As deaddrop chat is removed, this call can't
  be used anymore.
- dc_msg_get_real_chat_id(): use dc_msg_get_chat_id() instead, the
  only difference between these calls was in handling of deaddrop chat
- removed DC_CHAT_ID_DEADDROP and DC_STR_DEADDROP constants

f820671d53 Use Auto-Submitted: auto-generated header to identify bots
New `dc_msg_is_bot()` C API and corresponding `Message.is_bot()`
Python API can be used to check if incoming message is sent by a bot,
e.g. to avoid two echo bots replying indefinitely to each other.

"Bot" flag is not set for outgoing messages, but may be set for
BCC-self messages. For now documentation says that `dc_msg_is_bot()`
return value is unspecified for outgoing messages. It can be better
specified later if needed for specific applications, e.g. sharing an
account with a helper bot.

Fix https://github.com/deltachat/deltachat-android/issues/1940, fix https://github.com/deltachat/deltachat-core-rust/issues/2220 (I assume these are the same bug)

The problem was:
- Gmail adds a header `Bcc: <self-address>` to our bcc-self message
- `to_id` was just set to the first recipient, in this case _self_
- it was seen that `to_id` is _self_, so it's a self-sent message

adac903818 Debloat the binary by using less AsRef arguments
Using `impl AsRef<str>` as the argument instead of `&str` makes it
possible to call the function with `&str`, `String` and other types
that implement `AsRef` trait.

The cost of it is that compiled binary contains mulitple versions of
the same function, one for each variant of types. If function contains
multiple generic `impl AsRef` arguments, the number of versions possibly
compiled into binary grows exponentially with the number of arguments.

Simple way to avoid it is to call `.as_ref()` on the caller side to
convert the argument to `&str`. In most cases even adding a `&` and
relying on `Deref` coercion is sufficient.

This patch changes many functions that accepted `impl AsRef<str>` and
`impl AsRef<Path>` to accept `&str` and `&Path` instead.

In some places `.clone()` calls are removed. Calling `.clone()` on
`String` and passing `String` to a function accepting `impl
AsRef<str>` is completely unnecessary as `&str` reference could be
passed instead. There is no clippy warning against it yet, but
changing argument type to `&str` allowed to find these cases.

The result of debloating is not impressive, several hundred kilobytes
are saved, which is about 3% of the `.so` binary, but the code is
cleaner too.

0fa90a81e5 prefer X-Microsoft-Original-Message-ID, if set
outlooks SMTP-server change the Message-ID of messages
and put the original Message-ID to X-Microsoft-Original-Message-ID.

the changed Message-ID has some issues:

- outgoing messages with bcc_self enabled are shown twice
  as the self-copy got the changed Message-ID while the database uses
  the original one

- read receipts do not work as they refer to the changed message id

- in general, sender and recipient see different Message-IDs

the issues can be fixed by

(1) let all receivers use the original Message-ID

	this is what this pr is doing
    and this should fix all issues with delta-to-delta communication,
	including groups, group-images etc.
    there may be issues left in communication
	with other MUAs as they are using another Message-ID.

(2) ftr: updating the Message-ID in the database of the sender to the new one

	this requires bcc_self always enabled (which is not the case)
    and may also result easily in race conditions
    (Bob answers before Alice sees its self-sent message),
    however, has the advantage of better compatibility with other MUA.

if needed, the compatibility with other MUA could be improved by remembering
both Messages-IDs, maybe we could treat the modified as References or so,
however, i think, this could be part of another PR if we know better about
real, in the wild issues.

29f184b4c4 Strongly type stock strings
This changes the internal stock strings API to be more strongly typed,
ensuring that the caller can not construct the stock string in the
wrong way.

The old approach left it to the callers to figure out how a stock
string should be created, now each stock string has their specific
arguments and callers can not make mistakes.  In particular all the
subtleties and different ways of calling stock_system_msg() disappear.

This could not use a trait for stock strings, as this would not allow
having per-message typed arguments.  So we needed a type per message
with a custom method, only by convention this method is .stock_str().
The type is a enum without variants to avoid allowing someone to
create the type.

Sadly the fallback string and substitutions are still far away from
each other, but it is now only one place which needs to know how to
construct the string instead of many.

396ec131fc Implement receiving mailing lists (#1964)
* Copypaste-merge my old work

* Start implementing mailinglists the new way

* Create pseudo contact

* Fine-tune docs

* Remove some unnecessary changes

* style

* Make a stock str

* Fix a crash. Yes, this line caused a panic when reconfiguring on Android

(without a reasonable error log). Also, I could not receive any messages
anymore.

* rfmt

* Add tests and make them pass

* Even more tests

* rfmt

* Enhance test and fix bug

* Don't update the sender name when prefetching because maybe it's a mailing list

* Use an enum instead of numbers for the decision

* Don't remove anyone from mailing lists

* Fix bug in the regex

* Adjust error msg

* Compile error after rebase

* Correctly emit event

* Add dc_msg_is_mailing_list so that you can find out whether messages in the deaddrop belong to mailing lists.

* Add received headers to unit tests

* Comments, small tweaks

* Use dc_msg_get_override_sender_name instead of dc_msg_get_sender_name

* Add dc_msg_get_sender_first_name() because sometimes the first name was not correctly shown in mailing lists

* small fixes, don't let the user modify mailing list groups

* Hide contacts for addresses like noreply@github.com and reply+AEJ...@reply.github.com

When testing mailing lists, I noticed that sometimes a mailing list
contact got a name (like, hocuri <noreply@github.com>). It turned out
that ages ago, I had accidentally written an email to - in this example
- hocuri <noreply@github.com> and it had been added to the contacts
list.

This hides email addresses from the contacts list that are obviously not
meant to be written at and prevents updating the names.

* Comment, clippy

* Replace u32 with ChatId

* Resolve lost of small issues from the reviews

* remove dc_msg_get_sender_first_name

* add dc_msg_get_real_chat_id()

this allows to check if a contact request belongs to a mailing list
and to show name/avatar/whatever of the mailinglist.

another approach was to duplicate some chat-apis for messages
(eg. dc_msg_is_mailing_list()) however that would require far more new apis.

the idea to change the behavior of dc_msg_get_chat_id() would be
more clean, however, that easily breaks existing implementations
and can led to hard to find bugs.

* remove now unused Message.is_mailing_list()

* if a name for a mailing list is missing, use List-ID

* fix comment

* fix error message

* document how dc_get_chat_contacts() works for mailing lists

* refine decide api (#2185)

* add DC_DECIDE* constants to deltachat.h, tweak documentation

* use StartChat/Block/NotNow instead of Yes/Never/NotNow

* decide_on_contact_request works on ctx/msg-id

functions working on message-objects
usually do not read or write directly on the database.

therefore, decide_on_contact_request()
should not work with message-objects as well,
it is even a bit misleading, as eg. chat-id of the object is not modified.

instead, the function works on context,
similar to dc_send_msg(), dc_create_chat() and so on.
for now, i moved it to context, could maybe be part od MsgId.

* Update src/chatlist.rs

Co-authored-by: Hocuri <hocuri@gmx.de>

* refine documentation

* re-add accidentally deleted Param::MailingList

* remove pseudo-contact in domain @mailing.list

1. the pseudo-contact was added to the mailing list contacts,
   which is not needed.
   might be that we want to add the recent contacts there in a subsequent pr
   (we do not know all contacts of a mailing list)

2. the pseudo-contact was used to block
   mailing lists; this is done by setting the chat to Blocked::Manually now

3- the pseudo-contact was used for unblocking;
   as it is very neat not to require additional ui for mailing list unblocking,
   might be that we introduce a similar pseudo-contact for this limited purpose
   in a subsequent pr, however, the pseudo-contact needs to exist only
   during unblocking then, maybe also the special domain is not needed,
   we'll see :)

* Move dc_decide_on_contact_request() up to the dc_context section as it's a member of dc_context now

More specifically, to the "handle messages" section

* re-introduce Chattype::Mailinglist (#2195)

* re-introduce Chattype::Mailinglist

* exhaustive chattype-check in fetch_existing_msgs() and get_summary2()

* exhaustive chattype-check in ndn_maybe_add_info_msg()

* exhaustive chattype-check in message::fill()

* remove dc_chat_is_mailing_list() from ffi
