[RFC 2426][1] says:
> The binary data MUST be encoded using the "B" encoding format.
> Long lines of encoded binary data SHOULD BE folded to 75 characters
> using the folding method defined in [MIME-DIR].
That implies that whitespace may occur in binval data and we thus must
be able to parse this correctly.

Other additional checks are already gated by the absence of this
feature. As the MR to remove these checks altogether is still blocked,
this should serve as at least as an intermediate solution to anyone
affected by buggy remote implementations.
This does not matter much because users need to replace usages of these
anyway, but it's better to have it right here to not cause additional
confusion.
This moves InnerJid into Jid and reformulates BareJid and FullJid in
terms of Jid.
Doing this has the key advantage that FullJid and BareJid can deref to
and borrow as Jid. This, in turn, has the advantage that they can be
used much more flexibly in HashMaps. However, this is (as we say in
Germany) future music; this commit only does the internal reworking.
Oh and also, it saves 20% memory on Jid objects.
Fixes#122 more thoroughly, or rather the original intent behind it.
This provides a non-copying API, which is generally favourable. The
other accessors were removed, because the intent was to provide this
"most sensible" API via the "default" (i.e. shortest, most concisely
named) functions.
This introduces a str-like type for each of these, which will allow
returning a ref instead of the copied data from various methods in
{Full,Bare}Jid.
The use of a macro ensures that all types are declared consistently.
This allows constructs like:
```rust
let residual = match Iq::try_from(stanza) {
Ok(iq) => return handle_iq(..),
Err(Error::TypeMismatch(_, _, v)) => v,
Err(other) => return handle_parse_error(..),
};
let residual = match Message::try_from(stanza) {
..
};
let residual = ..
log::warn!("unhandled object: {:?}", residual);
```
The interesting part of this is that this could be used in a loop over a
Vec<Box<dyn FnMut(Element) -> ControlFlow<SomeResult, Element>>, i.e. in
a parsing loop for a generic XML/XMPP stream.
The advantage is that the stanza.is() check runs only once (in
check_self!) and doesn't need to be duplicated outside, and it reduces
the use of magic strings.
Since Rust 1.76, and some much older nightly, there have been
improvements to the niche computation, which leads to smaller types
which can encode the same amount of data, variants, and such.
This fixes the tests on this compiler version.
