Update tokio_rustls, idna, webpki_roots.

https://github.com/rustls/rustls/releases/tag/v%2F0.22.0
> ConfigBuilder::with_safe_defaults - calls to this can simply be deleted since safe defaults are now implicit.
> OwnedTrustAnchor - use rustls_pki_types::TrustAnchor instead, and replace from_subject_spki_name_constraints with direct assignment to the struct fields.

`RootCertStore::add_trust_anchors` seems to be removed too.

This codec system was useful for the previous parser style, but we have
converted them all to xso now!

The API changed here, URI became Uri to be more in line with the coding
style.

Also we don’t attempt to trim them any more because that was only used
in the examples, and nowhere in the text of the specification did it say
that those had to be trimmed.

As its name implies, this codec emits an error when the parsed string is
empty.

This codec converts from a colon-separated case-insensitive hexadecimal
string into a Vec of bytes, and back to a lowercase colon-separated
hexadecimal string.  Each byte must be separated by exactly one colon.

This codec converts from a fixed-size case-insensitive hexadecimal
string into an array of bytes, and back to a lowercase hexadecimal
string.

We are close to the release!

xmpp-parsers has stopped reexporting them, instead it reexports only the
crates themselves.

Let’s continue reexporting jid and minidom, but not their inner pub
items, users of this crate can go one level deeper if they need that.

Only xso::error::Error is still useful to reexport, as this is part of
the public API of all of our parsers.

This only has to be a bool, no need for this Option<bool>.

Analogous to the already existing `IntoXml` implementation helpers
based on an `Into<Element>` implementation on a type, this provides
the utilities for `AsXml`.

This is of course exceptionally inefficient, but it is only needed
transitionally until we have everything migrated to derive macros or
otherwise rewritten in terms of AsXml/FromXml.

This will soon replace the IntoXml trait. The idea here is that we
don't generally need to take ownership of values which are going to
be transformed into XML: most of the time, the XML text is created
by building a string from some more specific type, such as an
integer or an enum. Requiring to clone an entire structure for this
purpose is wasteful.

In other cases, we actually could reference data right from the structs
we are converting to XML. In those cases, assuming that an iterator
always generates owned data would be incorrect, too.

Hence, we introduce a new `Item` type which closely mirrors the
`rxml::Item` type, but where the constituents are `Cow`. In the upcoming
changes, we are going to work toward replacing all uses of `IntoXml`
with `AsXml`, as well as modifying the macros accordingly.

By defining the variables in the parent scope, we can avoid one level of
indentation for the tuple, which makes things more readable.

Additionally, we don’t need to call .to_str() on the passed objects,
they automatically Deref to &str for the format!() call.

This depends on XEP-0313 for its MAM metadata, and many others such as
XEP-0198, XEP-0280 and XEP-0352 for the inline features, but we
currently provide those as minidom Elements instead.
