2c7d51f98f feat: add "e2ee encrypted" info message to all e2ee chats (#7008)
this PR adds a info message "messages are end-to-end-encrypted" also for
chats created by eg. vcards. by the removal of lock icons, this is a
good place to hint for that in addition; this is also what eg. whatsapp
and others are doing

the wording itself is tweaked at
https://github.com/deltachat/deltachat-android/pull/3817 (and there is
also the rough idea to make the message a little more outstanding, by
some more dedicated colors)

~~did not test in practise, if this leads to double "e2ee info messages"
on secure join, tests look good, however.~~ EDIT: did lots of practise
tests meanwhile :)

most of the changes in this PR are about test ...

ftr, in another PR, after 2.0 reeases, there could probably quite some
code cleanup wrt set-protection, protection-disabled etc.

0a73c2b7ab feat: Show broadcast channels in their own, proper "Channel" chat (#6901)
Part of #6884 

----

- [x] Add new chat type `InBroadcastChannel` and `OutBroadcastChannel`
for incoming / outgoing channels, where the former is similar to a
`Mailinglist` and the latter is similar to a `Broadcast` (which is
removed)
- Consideration for naming: `InChannel`/`OutChannel` (without
"broadcast") would be shorter, but less greppable because we already
have a lot of occurences of `channel` in the code. Consistently calling
them `BcChannel`/`bc_channel` in the code would be both short and
greppable, but a bit arcane when reading it at first. Opinions are
welcome; if I hear none, I'll keep with `BroadcastChannel`.
- [x] api: Add create_broadcast_channel(), deprecate
create_broadcast_list() (or `create_channel()` / `create_bc_channel()`
if we decide to switch)
  - Adjust code comments to match the new behavior.
- [x] Ask Desktop developers what they use `is_broadcast` field for, and
whether it should be true for both outgoing & incoming channels (or look
it up myself)
- I added `is_out_broadcast_channel`, and deprecated `is_broadcast`, for
now
- [x] When the user changes the broadcast channel name, immediately show
this change on receiving devices
- [x] Allow to change brodacast channel avatar, and immediately apply it
on the receiving device
- [x] Make it possible to block InBroadcastChannel
- [x] Make it possible to set the avatar of an OutgoingChannel, and
apply it on the receiving side
- [x] DECIDE whether we still want to use the broadcast icon as the
default icon or whether we want to use the letter-in-a-circle
- We decided to use the letter-in-a-circle for now, because it's easier
to implement, and I need to stay in the time plan
- [x] chat.rs: Return an error if the user tries to modify a
`InBroadcastChannel`
- [x] Add automated regression tests
- [x] Grep for `broadcast` and see whether there is any other work I
need to do
- [x] Bug: Don't show `~` in front of the sender's same in broadcast
lists

----

Note that I removed the following guard:

```rust
        if !new_chat_contacts.contains(&ContactId::SELF) {
            warn!(
                context,
                "Received group avatar update for group chat {} we are not a member of.", chat.id
            );
        } else if !new_chat_contacts.contains(&from_id) {
            warn!(
                context,
                "Contact {from_id} attempts to modify group chat {} avatar without being a member.",
                chat.id,
            );
        } else [...]
```

i.e. with this change, non-members will be able to modify the avatar.
Things were slightly easier this way, and I think that this is in line
with non-members being able to modify the group name and memberlist
(they need to know the Group-Chat-Id, anyway), but I can also change it
back.

416131b4a2 feat: key-contacts
This change introduces a new type of contacts
identified by their public key fingerprint
rather than an e-mail address.

Encrypted chats now stay encrypted
and unencrypted chats stay unencrypted.
For example, 1:1 chats with key-contacts
are encrypted and 1:1 chats with address-contacts
are unencrypted.
Groups that have a group ID are encrypted
and can only contain key-contacts
while groups that don't have a group ID ("adhoc groups")
are unencrypted and can only contain address-contacts.

JSON-RPC API `reset_contact_encryption` is removed.
Python API `Contact.reset_encryption` is removed.
"Group tracking plugin" in legacy Python API was removed because it
relied on parsing email addresses from system messages with regexps.

81a6afde15 Fix(jsonrpc): Do not error on missign webxdc info (#6866)
When an invalid webxdc is set as draft, json-rpc's `get_draft` fails,
because `get_webxdc_info` which it calls, fails because the zip reader
can not read a non-zip file. With this change, any error occurring in
`get_webxdc_info` is ignored and the None-variant is returned instead. I
also added a test, that setting invalid xdcs is draft is fine core-wise
and checked that the input field stays responsive when a fake.xdc
produced like in #6826 is added to draft

21d13e8a9c fix: Don't change webxdc self-addr when saving and loading draft (#6854)
Fix https://github.com/chatmail/core/issues/6621; I also tested on
Android that the webxdc self-addr actually stays the same when staging a
draft and then sending.

Follow-up to https://github.com/chatmail/core/pull/6704; #6704 made sure
that the webxdc self-addr doesn't change when creating a message and
then sending it. This PR here makes sure that the rfc724_mid (which is
needed to compute the self-addr) is saved when setting a draft, so that
it's loaded properly after a call to get_draft().

846c8e7f1b Generate rfc724_mid when creating Message (#6704)
Set `rfc724_mid` in `Message::new()`, `Message::new_text()`, and
`Message::default()` instead of when sending the message. This way the
rfc724 mid can be read in the draft stage which makes it more consistent
for bots. Tests had to be adjusted to create multiple messages to get
unique mid, otherwise core would not send the messages out.

33b9a582f3 test: transfer vCards in TestContext.create_chat()
SecureJoin and importing a vCard are the primary
ways we want to support for creating contacts.
Typing in an email address and relying on Autocrypt
results in sending the first message unencrypted
and we want to clearly separate unencrypted and encrypted
chats in the future.

To make the tests more stable, we set up test contacts
with vCards as this always immediately
results in creating a single encrypted chat
and this is not going to change.

65a9c4b79b File deduplication (#6332)
When receiving messages, blobs will be deduplicated with the new
function `create_and_deduplicate_from_bytes()`. For sending files, this
adds a new function `set_file_and_deduplicate()` instead of
deduplicating by default.

This is for
https://github.com/deltachat/deltachat-core-rust/issues/6265; read the
issue description there for more details.

TODO:
- [x] Set files as read-only
- [x] Don't do a write when the file is already identical
- [x] The first 32 chars or so of the 64-character hash are enough. I
calculated that if 10b people (i.e. all of humanity) use DC, and each of
them has 200k distinct blob files (I have 4k in my day-to-day account),
and we used 20 chars, then the expected value for the number of name
collisions would be ~0.0002 (and the probability that there is a least
one name collision is lower than that) [^1]. I added 12 more characters
to be on the super safe side, but this wouldn't be necessary and I could
also make it 20 instead of 32.
- Not 100% sure whether that's necessary at all - it would mainly be
necessary if we might hit a length limit on some file systems (the
blobdir is usually sth like
`accounts/2ff9fc096d2f46b6832b24a1ed99c0d6/dc.db-blobs` (53 chars), plus
64 chars for the filename would be 117).
- [x] "touch" the files to prevent them from being deleted
- [x] TODOs in the code

For later PRs:
- Replace `BlobObject::create(…)` with
`BlobObject::create_and_deduplicate(…)` in order to deduplicate
everytime core creates a file
- Modify JsonRPC to deduplicate blob files
- Possibly rename BlobObject.name to BlobObject.file in order to prevent
confusion (because `name` usually means "user-visible-name", not "name
of the file on disk").

[^1]: Calculated with both https://printfn.github.io/fend/ and
https://www.geogebra.org/calculator, both of which came to the same
result

d63a2b39aa feat: allow the user to replace maps integration (#5678)
with this PR, when an `.xdc` with `request_integration = map` in the
manifest is added to the "Saved Messages" chat, it is used _locally_ as
an replacement for the shipped maps.xdc (other devices will see the
`.xdc` but not use it)

this allows easy development and adapting the map to use services that
work better in some area.

there are lots of known discussions and ideas about adding more barriers
of safety. however, after internal discussions, we decided to move
forward and also to allow internet, if requested by an integration (as
discussed at
https://github.com/deltachat/deltachat-core-rust/pull/3516).
the gist is to ease development and to make users who want to adapt,
actionable _now_, without making things too hard and adding too high
barriers or stressing our own resources/power too much.
note, that things are still experimental and will be the next time -
without the corresponding switch being enabled, nothing will work at
all, so we can be quite relaxed here :)

for android/ios, things will work directly. for desktop, allow_internet
needs to be accepted unconditionally from core. for the future, we might
add a question before using an integration and/or add signing. or sth.
completely different - but for now, the thing is to get started.

nb: "integration" field in the webxdc-info is experimental as well and
should not be used in UIs at all currently, it may vanish again and is
there mainly for simplicity of the code; therefore, no need to document
that.

successor of https://github.com/deltachat/deltachat-core-rust/pull/5461

this is how it looks like currently - again, please note that all that
is an experiment!

a6db7ba1e3 api: deprecate webxdc descr parameter (#6255)
this PR removes most usages of the `descr` parameter.

- to avoid noise in different branches etc. (as annoying on similar, at
a first glance simple changes), i left the external API stable

- also, the effort to do a database migration seems to be over the top,
so the column is left and set to empty strings on future updates - maybe
we can recycle the column at some point ;)

22b9308c9b feat: update.href api (#6248)
add `update.href` property option to update objects send via
`Context::send_webxdc_status_update()`.

when set together with `update.info`,
UI can implement the info message as a link that is passed to the webxdc
via `window.location.href`.
for that purpose, UI will read the link back from
`Message::get_webxdc_href()`.

Practically,
this allows e.g. an calendar.xdc
to emits clickable update messages
opening the calendar at the correct date.

29de7c3603 feat: webxdc notify (#6230)
this PR adds support for the property `update.notify` to notify about
changes in `update.info` or `update.summary`. the property can be set to
an array of addresses [^1]

core emits then the event `IncomingWebxdcNotify`, resulting in all UIs
to display a system notification, maybe even via PUSH.

for using the existing `update.info` and `update.summary`: the message
is no secret and should be visible to all group members as usual, to not
break the UX of having same group messages on all devices of all users -
as known already from the normal messages.

also, that way, there is no question what happens if user have disabled
notifications as the change is presented in the chat as well

doc counterpart at https://github.com/webxdc/website/pull/90

closes #6217 

[^1]: addresses come in either via the payload as currently or as an
explicit sender in the future - this does not affect this PR. same for
translations, see discussions at #6217 and #6097

242547f1e9 feat: experimental Webxdc Integration API, Maps Integration (#5461)
as discussed in several chats, this PR starts making it possible to use
Webxdc as integrations to the main app. In other word: selected parts of
the main app can be integrated as Webxdc, eg. Maps [^1]

this PR contains two parts:

- draft an Webxdc Integration API
- use the Webxdc Integration API to create a Maps Integration

to be clear: a Webxdc is not part of this PR. the PR is about marking a
Webxdc being used as a Map - and core then feeds the Webxdc with
location data. from the view of the Webxdc, the normal
`sendUpdate()`/`setUpdateListener()` is used.

things are still marked as "experimental", idea is to get that in to
allow @adbenitez and @nicodh to move forward on the integrations into
android and desktop, as well as improving the maps.xdc itself.
good news is that we currently can change the protocol between Webxdc
and core at any point :)


# Webxdc Integration API

see `dc_init_webxdc_integration()` in `deltachat.h` for overview and
documentation.

rust code is mostly in `webxdc/integration.rs` that is called by other
places as needed. current [user of the API is
deltachat-ios](https://github.com/deltachat/deltachat-ios/pull/1912),
android/desktop will probably follow.

the jsonrpc part is missing and can come in another PR when things are
settled and desktop is really starting [^2] (so we won't need to do all
iterations twice :) makes also sense, when this is done by someone
actually trying that out on desktop

while the API is prepared to allow other types of integrations (photo
editor, compose tools ...) internally, we currently ignore the type. if
that gets more crazy, we probably also need a dedicated table for the
integrations and not just a single param.

# Maps Integration

rust code is mostly in `webxdc/maps_integration.rs` that is called by
`webxdc/integration.rs` as needed.

EDIT: the idea of having a split here, is that
`webxdc/maps_integration.rs` really can focus on the json part, on the
communication with the .xdc, including tests

this PR is basic implementation, enabling to move forward on
integrations on iOS, but also on desktop and android.

the current implementation allows already the following:
- global and per-chat maps
- add and display POIs
- show positions and tracks of the last 24 hours

the current maps.xdc uses leaflet, and is in some regards better than
the current android/desktop implementations (much faster, show age of
positions, fade out positions, always show names of POIs, clearer UI).
however, we are also not bound to leaflet, it can be anything

> [**screenshots of the current
state**](https://github.com/deltachat/deltachat-ios/pull/1912)
> 👆

to move forward faster and to keep this PR small, the following will go
to a subsequent PR:

- consider allowing webxdc to use a different timewindow for the
location
- delete POIs
- jsonrpc 


[^1]: maps are a good example as anyways barely native (see android
app), did cause a lot of pain on many levels in the past (technically,
bureaucratically), and have a comparable simple api
[^2]: only going for jsonrpc would only make sense if large parts of
android/ios would use jsonrpc, we're not there
