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.

d3b66cf724 Remove obsolete ChatId::is_unset check
The get_chat_id_by_grpid() call is already resultified.  The database
can only contain consistent data since on creation it inserts rows for
the special chats which do not have a grpid set so can never match.
Thus we can safely remove another use of the ChatId::is_unset call
which should be removed to clean up the type.

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

ebccdbbcb9 Improve onboarding by scanning all folders from time to time (#2067)
Start implementing #1994

TODO (in later PRs):

- Add a hint to the watch settings that all folders are fetched from time to time (to be done in the individual UIs)
- folder names are case-insensitive, so double-check that all comparisons are case-insensitive
- The `scan_folders.rs` file didn't get as large as I expected and it's probably not worth it having an extra file for it. But if there are no objections, I'll make another PR to rename it to `folders.rs` and also put into it `configure_folders()` from `imap/mod.rs` and `needs_move()` with all its tests from `message.rs`.

Done:

- Most mailboxes have a "Drafts" folder where constantly new emails appear but we don't actually want to show them, what do we do about this? The most reliable way to detect such messages that we found up to now is:
  If there is no `Received` header AND it's not in the `ConfiguredSentbox`, then ignore the email.
- before or after INBOX idle trigger a new "scan all folders for messages".  It does a "list folders" and then goes through all folders with select-statements, checking if "next-uid" was changed since checked last time.  This might be batchable but in any case should not consume a lot of traffic. We might debounce this scan activity to happen at most every N minutes 

- if next-uid changed for a folder, we "prefetch" and "fetch" DC-messages as as needed ("dc-messages" are not just those with "Chat-Version" headers, but can also be regular emails) 

- if we discover DC-messages in folders that have the "/Spam" flag (maybe excluding ContactRequests) we automatically move them to INBOX/DeltaChat folder to help  provider-spam-systems to regard this contact/mail as non-spam 

- for now, we do not change any user visible option, but introduce this "scan all" automatically and on top of what exists.   The DeltaChat folder-watching does not perform scan-all-folders (maybe with the exception to trigger scan-all also with DeltaChat if INBOX is not watched)

- Tests (except if you have ideas to improve them)
- all folders, their last uidvalidity, next-seen etc. are kept in a separate "imap-sync" sqlite table.  Maybe this can be used to streamline some of the "Sent" folder and "DeltaChat" folder detection code we already have. 

- We now also move self-sent messages from the Inbox to the Sent folder if `mvbox_move` is off, as this was very easy to do now. This way, we now behave more like a normal MUA if the user wants this.

FOR LATER PRs:

- maybe for the first 50 messages or so, we could reduce the IDLE-timeout (currently 23 minutes or so) to faster detect messages sent to non-inbox folders. However, on Android and iOS, we would likely trigger scan-all when the app moves to foreground, and so  it might not be neccessary to reduce the current idle-timeout at least for them.  We can leave this "faster discovery" question for the end, after we move to real-life testing. 

- (Later on, after the above works, we can consider heuristics on which folders to perform IDLE on, and remove the Watch-folder options (inbox, deltachat, sent). We tried to find a safe scheme for already doing it but failed to fine one, too many unknowns, also some questions regarding multi-device (you might have different settings with each of it, one moves, the other doesn't etc.) so we postponed this in favor of the above incremental suggestion.)




* Start implementing #1994

* Add debug logs, it seems like the SQL migration can go into another pr

* Let fetch_new_messages return whether there are new emails

* Code style

* Don't prefetch if there are no new emails

* clippy

* Even more debug logs

* If the folder was not newly selected, return always try to fetch as

uid_next is probably outdated

* Fix new bug

* Recognize spam folder

* if we discover DC-messages in folders that have the "/Spam" flag (excluding ContactRequests) we automatically move them to INBOX/DeltaChat folder to help provider-spam-systems to regard this contact/mail as non-spam

* Clippy, prioritize folder_meaning over folder_name_meaning

* Add a first test, for the first day after installation only debounce to 2s

* Start adding two tests (both of them fail)

* Don't abort folder scan if one folder fails

* More consts

* Replace bool return value by enum

* Split test up into multiple tests

* Print logs during rust tests

* Rust tests pass now

* .

* One of the Python tests passes now - reconfigure folders during scanning

* Make the last test pass - Delete emails in all folders when starting the test, not only inbox and mvbox

The problem had been that emails were left in the folder "xyz"

* lint

* DB migration (untested)

* Store uid_next in SQL instead of lastseen in a config

* Revert "If Inbox-watch is disabled and enabled again, do not fetch emails from in between"

all folders are always watched, anyway

* clippy, rm debug logs, comments

* Codestyle, comments

* fixing things again

* Fix another test: don't fetch from uid_next-1 but uid_next; make some {} to {:#} so that we can use `.context(...)`

* move self-sent, non-setupmessage chat messages to the Sent folder if `mvbox_move` is off

* comment

* Comments, make sure things work even if there is no uid_next

* Style

* Comments

* The rust test tested wrongly

* comments, small codestyle change

* Ignore emails that are probably only drafts

Most mailboxes have a "Drafts" folder where constantly new emails appear
but we don't actually want to show them.
So: If there is no Received header AND it's not in the ConfiguredSentbox,
then ignore the email.

Also: Add test.

* Fix occasional test failure, it was introduced as DC now moves messages from Inbox to Sent

* Add `Received` header to the rust tests

* After this PR we will always watch all folders and delete messages there if server_delete is enabled. So, for people who have server_delete on, disable it and add a hint to the devicechat

* comment, small fix

* link2xt's first review

* Use ON CONFLICT(FOLDER) DO to update and if it doesn't exist, then insert

Reason from link2xt: We had a problem with multiple peerstates inserted due to key fingerprint parsing error previously. With logic in Rust a similar problem can occur: an UPDATE can fail for reasons other than a conflict. PRIMARY KEY should ensure uniqueness in this case, but anyway.

* Remove two TODO statements, remove fetch_new_messages: ignoring uid {}, uid_next was {} log

* Next TODO: Make uidvalidity and uid_next DEFAULT 0

* rm two TODOs, Seems like we are not going to `exclude folders that are watched anyway` in this PR

* small tweak: Handle instants more carefully

* Add scan_all_folders_debounce_secs config for tests, set debounce to 60s (before it was just 2s during the first day)

* Don't use bold letters for the device message

* React to changes in the folders better

Before, if there was a configured Sent folder, but then it got
removed and replaced with another folder with a name meaning "Sent" but
without Sent flag, it would be ignored.

So, instead of checking against ConfiguredSentboxFolder,
create two Option variables at the beginning of the loop and replace
them with Some if it is None. At the end of the loop, store the new
values into ConfiguredSendboxFolder and ConfiguredSpamFolder, even if it
is None.

Also, derive some useful traits.

* move job: Return a meaningful error if server_folder is None instead of panicing

* small error-handling fix

* Fix test_fetch_existing() python test

Before, we sometimes got a race condition where scan_folders() sees that
there is a Sentbox and saves this info after we set the
ConfiguredSentbox to None and before the message is sent.

So, just expect that the message is moved to the sentbox.

* migration is 72 now

* rm 2 TODOs, Don't infinitely retry when dc_receive_imf() returns Err

* clippy: Remove glob imports

* Delete created folders at the beginning of tests

(some created folders made problems in the next tests because)

* Improve resetting accounts between tests

f4c8ffca4c Query MX records during provider autoconfiguration
Previously MX records were queried only for OAuth 2 configuration and
did not affect the list of servers tried. User was required to manually
configure the servers for Google Workspace (former GSuite) domains.

Now MX records are queried during configuration. If provider is found in
offline database, its ID, corresponding to the filename, is saved as
`configured_provider`.

`configured_provider` is also set during database migration if email
address uses the domain from the provider database, but no MX querying
is done.

That's another narrow-stitching patch for a scenario where many emails could
be deleted all at once and surprisingly: user disables inbox-watch, enables delete-from-server, after a moth enables inbox-watch again -> currently all emails that arrived in the meantime will be deleted (if emails are not fetched, they won't be deleted)

e388e4cc1e Do not emit network errors during configuration
Previously DC_EVENT_ERROR_NETWORK events were emitted for each failed
attempt during autoconfiguration, even if eventually configuration
succeeded. Such error reports are not useful and often confusing,
especially if they report failures to connect to domains that don't
exist, such as imap.example.org when mail.example.org should be used.

Now DC_EVENT_ERROR_NETWORK is only emitted when attempting to connect
with existing IMAP and SMTP configuration already stored in the
database.

Configuration failure is still indicated by DC_EVENT_CONFIGURE_PROGRESS
with data1 set to 0. Python tests from TestOnlineConfigurationFails
group are changed to only wait for this event.
