set_err_kind() is a method of the IntoError trait, not an Error method;
it is meant to be used for any error type that can be converted into
Error. Since melib::Error implements Into<melib::Error> tautologically,
this was not a compilation error. Nevertheless, the correct thing to do
is use the type method directly to set ErrorKind.

Flag and tag modifications are now somewhat typed better, and the
frontend applies them on its own on success. This means that if you set
an unseen mail as seen but it was already seen in the backend, you will
see the change locally. Previously it would remain unseen.

This commit adds a Happy Eyeballs [1] implementation taken from the
happy-eyeballs crate, which is in public domain.
While the function lookup_ip[0] iterates through the addresses returned by
A and AAAA records from a DNS lookup, it returns the first one which
always is an IPv4 address, unless there only is an AAAA record.
RFC6555 [1] recommends an algorithm for choosing the fastest address to
connect to, called "Happy Eyeballs". Ꙭ

According to RFC 3977:
> Command lines MUST NOT exceed 512 octets, which includes the
> terminating CRLF pair
This commit adds a log::error entry when any sent command exceeds that
limit and recommends the user to report this as a bug.
According to RFC 3977:
> Command lines MUST NOT exceed 512 octets, which includes the
> terminating CRLF pair
Sending a `LIST ACTIVE` command with lots of newgroups and passing the
512 byte limit is therefore invalid. This commit splits the mailboxes in
chunks and sends a separate command for each maximal chunk that has
a valid length.
Fixes#269.

NNTP servers may return addresses that are not RFC 5322 compliant. An
address with a comment with non-ascii characters will make the parser loop indefinitely.
Fixes#269.
