`xmpp_parsers::stanza_error::StanzaError` has been moved into the
corresponding enum variants of the
`xmpp_parsers::stanza_error::DefinedCondition` where it may occur.
- The `xmpp_parsers::mix::Participant::jid` and `..::Mix::jid` fields
are now of type `BareJid` (instead of `String`), as they should always
have been. This influences various other places, such as these
struct's constructors.
* New parsers/serialisers:
- Stream Features (RFC 6120) (!400)
