Small strings are always copied fully, without allocations.
Large transient strings copy the data and allocate.
Large persistent strings are also a trivial copy.

Fix a discrepancy in the error message for DirectoryError::SizeOverflow.
The message indicates that the SizeOverflow error occurs when total size
exceeds u32::MAX, but that's not true. All size fields within the
castore's internal Directory ADT are u64, and the SizeOverflow error is
only returned after a call to the checked_add implementation on u64.

This moves the URL component parsing code we had in nar-bridge to
nix-compat.
We change the function signature to return an Option, not a
Result<_, StatusCode>.
This allows returning more appropriate error codes, as we can
ok_or(…) at the callsite, which we now do: on an upload to an
invalid path, we now return "unauthorized", while on a GET/HEAD, we
return "not found".
This also adds support to parse compression suffixes. While not
supported in nar-bridge, other users of nix-compat might very well want
to parse these paths.
Also fix the error message when parsing NAR urls, it mentioned 32, not
52, which is a copypasta error from the narinfo URL parsing code.

Similar to how cl/12253 already did this for `Signature`, we apply the
same logic to `StorePath`.
`StorePathRef<'a>'` is now a `StorePath<&'a str>`, and there's less
redundant code for the two different implementation.
`.as_ref()` returns a `StorePathRef<'_>`, `.to_owned()` gives a
`StorePath<String>` (for now).
I briefly thought about only publicly exporting `StorePath<String>`
as `StorePath`, but the diff is not too large and this will make it
easier to gradually introduce more flexibility in which store paths to
accept.
Also, remove some silliness in `StorePath::from_absolute_path_full`,
which now doesn't allocate anymore.

This implements a simple DFS locator in listing structures.
It is interoperable with the Rust standard library paths, we also build our
own errors to restrict path values to reasonable secure defaults, e.g.
relative paths with no `..` component.
Tests are added for this new feature for a positive and a negative
check.
In addition, a path validation test was added. The Windows-style prefix
is gated on the Windows platform as UNIX does not parse `C:\\` as a
`Component::Prefix(_)` but as a `Component::Normal(_)`.

Requiring `name` to be a `&str` means it'll get annoying to pass around
`Signature`, but being able to pass them around in an owned fashion is
kinda a requirement for a stronger typed `PathInfo` struct, where we
want to have full ownership.
Rework the `Signature` struct to become generic over the type of the
`name` field. This means, it becomes possible to have owned versions
of it.
We don't want to impose `String` or `SmolStr` for example, but want to
leave it up to the nix-compat user to decide.
Provide a type alias for the existing `&str` variant (`SignatureRef`),
and use it where we previously used the non-generic `Signature` one.
Add some tests to ensure it's possible to *use* `Signature` with both
`String` and `SmolStr` (but only pull in `smol_str` as dev dependency
for the tests).
Also, add some more docstrings, these were a bit sparse.

Makes it possible to construct a GermanString from an owned byte vector, without
having to clone the data.
This is done by "disowning" the vector using ManuallyDrop to access its internal
pointer. For transient strings, this memory is then owned (and freed) by the
GermanString instance.
Small strings are copied out of the heap and stored inline as before, to avoid
any dereferencing operations.
