Xeps/bind2 inlines

[NelsonVides]

This PR introduces BIND2 support for carbons, csi, and sm.

As described in

• https://xmpp.org/extensions/xep-0388.html (SASL2 XEP)
• https://xmpp.org/extensions/xep-0386.html (BIND2 XEP)
• XEP-0198: Add section defining SASL2 and BIND2 interaction xsf/xeps#1215 (changes to the stream-management XEP specifying the interactions with SASL2 and BIND2)

Note that the changes to SM are not accepted yet (at the moment of writing), and for a while they claimed the SM feature inlined into SASL2 should be announced as resume but then it was requested it should announce sm, as other XMPP servers and clients have already done.

Looks good 👍

I think that given/when/then prefixes in helpers are confusing, but it can be a matter of preference. For me they hinder code reuse, e.g. here we have a then in given, which already breaks the pattern. If the helper function was called assert_client_does_not_receive_any_message, it would look cleaner.

So we could get rid of the given/then prefixes, but I see how this code was moved from a suite, so it can stay as it is.
