This commit executes maint/add_warning with the just added change to
deny string slices except in tests.
I recommend auditing this by checking out the previous commit followed
by running the script yourself and then verifying that the diff is
identical to this commit.
This commit makes cargo clippy fail. We will add exceptions in the next
commit.

The methods in ParseRouterStatus can now be inherent.
This starts a cascade of unused stuff, and stuff which doesn't need to
be pub any more.

- Replaced `once_cell::sync::Lazy` with `std::sync::LazyLock`.

I'm about to make our parsers reject some strings at construction
time, so it makes sense to have these functions become fallible.
This is a breaking change.

FTR I don't think agree with clippy on this question, but then I often
don't.

`ParseErrorKind` was renamed to `NetdocErrorKind`, so we need to
rename this acccessor too.

`ParseErrorSource` was originally meant to represent a parsing error,
this enum has since gained some variants that aren't really parsing
related (`Signature`, `CertSignature`, `UntimelyDescriptor`).
Since this error type is now used for general-purpose netdoc errors,
let's rename `ParseError{Kind, Source}` to `NetdocError{Kind, Source}`.

There's a blanket impl of Itertor for &mut impl Iterator, so this
isn't necessary, and it prevents us passing iterators by value
producing syntactic vinegar.

Now we require that, for all `SectionRules`, either the caller say
how to handle unrecognized tokens (using `.add(UNRECOGNIZED...)`),
or that they explicitly reject unrecognized tokens (using
`reject_unrecognized`()`.)
This solution uses an assert!() rather than an Error to indicate
failure. I say that's fine, since
1. This is a crate-internal API.
2. We never dynamically construct SectionRules according to
different behavior: they are always prefabricated in a fixed
code block. Thus, if we test a parser at all, we will make
sure that its SectionRules are well-formed.
I considered and explicitly rejected a solution where the builder
had to be finalized with separate methods `build_strict()` or
`build_tolerant()`: It's too easy IMO for the caller to forget what
these call means.
Prevents further recurrences of #752.
Closes #752.

No new behavior yet.

This panics on error, and we're fine with a panic on misbehavior in
tests.

Clippy now warns about these; I'm not sure how these warnings snuck
up on us.

This is precisely the result of running the rune in
maint/adhoc-add-lint-blocks.

It looks like, despite a few false starts, they've got this warning
right; there weren't any false positives.

We already have `Pos::Unknown` for an error at an unknown
location and `Pos::None` for an error where no location is
sensible. There's no reason to have an additional `Option` here.
Additionally, the use of `Option` gave us a bug where our old
`ParseError::at_pos()` method didn't actually set the position
unless the position was already set. That's not what we want!
Fixes #640.
Finally, we have to fix a test that was a bit broken because it was
working around #640.

This enum was otiose: its set of valid values is precisely those of a
Vec. (Indeed what would TokVal::Multi(vec![]) have meant?)

std::slice::from_ref exists. Spotted while reviewing !400

This error type doesn't impement HasKind, since the kind will depend
on context.
However, the existing implementation was pretty messy and inconsistent:
Some errors had positions, some didn't.
Some took messages as str, some as String.
Some had internal errors that were somewhat orthogonal to their actual
types.
This commit refactors tor_netdoc::Error to use a ParseErrorKind, and
adds a set of convenience functions to add positions and
messages to the errors that need them.

This will cause some pain for now, but now is really the best time
to do this kind of thing.
