* add dc_resend_msgs() to ffi * add 'resend' to repl * implement resend_msgs() * allow only resending if allowed by chat-protection this means, resending is denied if a chat is protected and we cannot encrypt (normally, however, we should not arrive in that state) * allow only resending of normal, non-info-messages * allow only resending of own messages * reset sending state to OutPending on resending the resulting state is always OutDelivered first, OutMdnRcvd again would be applied when a read receipt is received. preserving old state is doable, however, maybe this simple approach is also good enough, at least for now (or maybe the simple approach is even just fine :) another thing: when we upgrade to resending foreign messages, we do not have a simple way to mark them as pending as incoming message just do not have such a state - but this is sth. for the future.

On Windows, you may need to also install Perl to be able to compile deltachat-core.
Using the CLI client
Compile and run Delta Chat Core command line utility, using cargo:
$ RUST_LOG=repl=info cargo run --example repl --features repl -- ~/deltachat-db
where ~/deltachat-db is the database file. Delta Chat will create it if it does not exist.

If yourfriend@email.org uses DeltaChat, but does not receive message just
sent, it is advisable to check Spam folder. It is known that at least
gmx.com treat such test messages as spam, unless told otherwise with web
