Now that we are deduplicating everywhere, we can get rid of some code.
The old python bindings did not get an optional `name` parameter because
they are deprecated anyway, but it would be easy to add it.
> _greetings from the ice of the deutsche bahn 🚂🚃🚃🚃 always a pleasure to
see how well delta chat meanwhile performs in bad networks :)_
this PR adds an API to request other chat members to replace the message
text of an already sent message. scope is mainly to fix typos. this
feature is known from whatsapp, telegram, signal, and is
[requested](https://support.delta.chat/t/retract-edit-sent-messages/1918)
[since](https://support.delta.chat/t/edit-messages-in-delta-chat/899)
[years](https://github.com/deltachat/deltachat-android/issues/198).
technically, a message with an
[`Obsoletes:`](https://datatracker.ietf.org/doc/html/rfc2076#section-3.6)
header is sent out.
```
From: alice@nine
To: bob@nine
Message-ID: 2000@nine
In-Reply-To: 1000@nine
Obsoletes: 1000@nine
Edited: this is the new text
```
the body is the new text, prefixed by the static text `Edited:` (which
is not a header). the latter is to make the message appear more nicely
in Non-Delta-MUA. save for the `In-Reply-To` header. the `Edited:`
prefix is removed by Delta Chat on receiving.
headers should be protected and moved to e2ee part as usual.
corrected message text is flagged, and UI should show this state, in
practise as "Edited" beside the date.
in case, the original message is not found, nothing happens and the
correction message is trashes (assuming the original was deleted).
question: is the `Obsoletes:` header a good choice? i _thought_ there is
some more specifica RFC, but i cannot find sth. in any case, it should
be an header that is not used otherwise by MUA, to make sure no wanted
messages disappear.
what is NOT done and out of scope:
- optimise if messages are not yet sent out. this is doable, but
introduces quite some cornercaes and may not be worth the effort
- replaces images or other attachments. this is also a bit cornercasy
and beyond "typo fixing", and better be handled by "delete for me and
others" (which may come soon, having the idea now, it seems easy :)
- get edit history in any way. not sure if this is worth the effort,
remember, as being a private messenger, we assume trust among chat
members. it is also questionable wrt privacy, seized devices etc.
- add text where nothing was before; again, scope is "typo fixing",
better avoid cornercases
- saved messages are not edited (this is anyway questionable)
- quoted texts, that are used for the case the original message is
deleted, are not updated
- edits are ignored when the original message is not there yet (out of
order, not yet downloaded)
- message status indicator does not show if edits are sent out or not -
similar to reactions, webxdc updates, sync messages. signal has the same
issue :) still, connectivity should show if there are messages pending

This makes it so that files will be deduplicated when using the JsonRPC
API.
@nicodh and @WofWca you know the Desktop code and how it is using the
API, so, you can probably tell me whether this is a good way of changing
the JsonRPC code - feel free to push changes directly to this PR here!
This PR here changes the existing functions instead of creating new
ones; we can alternatively create new ones if it allows for a smoother
transition.
This brings a few changes:
- If you pass a file that is already in the blobdir, it will be renamed
to `<hash>.<extension>` immediately (previously, the filename on the
disk stayed the same)
- If you pass a file that's not in the blobdir yet, it will be copied to
the blobdir immediately (previously, it was copied to the blobdir later,
when sending)
- If you create a file and then pass it to `create_message()`, it's
better to directly create it in the blobdir, since it doesn't need to be
copied.
- You must not write to the files after they were passed to core,
because otherwise, the hash will be wrong. So, if Desktop recodes videos
or so, then the video file mustn't just be overwritten. What you can do
instead is write the recoded video to a file with a random name in the
blobdir and then create a new message with the new attachment. If
needed, we can also create a JsonRPC for `set_file_and_deduplicate()`
that replaces the file on an existing message.
In order to test whether everything still works, the desktop issue has a
list of things to test:

Core issue: #6265

This hopefully does not trigger Apple spam filter
which seems to pass thorugh Message-IDs with hyphens.
It is not confirmed, but better blend in
by mimicking existing popular email
where possible.
With iOS and Desktop copying the file to a to a temp file with the name
of `get_filename()`, it should be sanitized first.
The PR can be reviewed commit-by-commit or all at once.
This task is not guaranteed to be cancellation-safe
and provides a stop token for safe cancellation instead.
We should always cancel the task properly
and not by racing against another future.
Otherwise following call to Handle.done()
may work on IMAP session that is in the middle
of response, for example.
this converts old QR codes to the new format, in an hacky, but simple
way, see #6518 for more details and for code snippet
then QR code change is esp. bad as ppl will have different versions for
some days at least, weakening overall UX, esp. of first-time-users that
may come to delta because of praised, seamless multidevice ... :)
i tested in https://github.com/deltachat/deltachat-ios/pull/2595 that
this actually fixes the problem, and there is no deeper issue with
changed chashes or so - seemed not to be the case, at least, with this
hack, core accepts QR codes from the released 1.52-and-before series
this hack gives user time to update, it can be removed after some months
(we can also remove the old BACKUP qr code alltogether then)
we should still not wait too long with the PR as there are already
versions out with the "new/bad" QR code (and growing, as new iOS
installations will get the new format, one cannot revert a version, only
pause rollout)

This change adds a test and updates mailparse from 0.15.0 to 0.16.0.
mailparse 0.16.0 includes a fix for the bug
that resulted in CRLF being included at the end of the body.
Workaround for the bug in the `pk_validate` function is also removed.
APNS tokens never expire unless
the user uninstalls the application.
Because of this in most cases
the token remains valid forever
and chatmail server never removes the token
even if it is unencrypted
or the user has removed Delta Chat profile
from the device but not the whole application.
We want to modify chatmail servers
to remember the last time the token was stored
and remove them after some time.
Before we do this, we need to modify
the client to store the device token
each time so the server knows which tokens are used
and can update their timestamps.
QR code format changed because `NodeAddr` serialization
changed between iroh 0.29.0 and iroh 0.30.0.
We have already released iroh 0.30.0,
so the test at least makes change we don't break compatibility again.
