because we return `libimagstore::iter::Entries` here now, we do not have
to pass the store anymore.

With this change applied, libimagstore does not export backend
representing types anymore.
This change is necessar because when we want to switch the `StoreId`
implementation from "complex and stateful" to "Stateless and Cow<'_,
&str>", we need to be able to have a type which represents a "`StoreId`
plus the path of the Store itself".
This "the path of the Store itself" is passed around as reference, to
minimize runtime impact.
Because such a type should not be exported by the libimagstore crate, we
make it `pub(crate)` internally. But because the backend APIs also have
to use this type, we would export the (private) type in the APIs of the
backend.
Because of that we make the backend API also non-visible to crate users,
which also decreases the surface of the libimagstore API itself.
Besides:
Remove function `Link::with_base()` which is not needed anymore (was
used in tests only).

This way we alter the underlying iterator for all wiki entries to only
iterate in the "wiki" collection of the store, which results in fewer
disk access because the internal iterator does not yield all pathes from
the store before filtering them.
Code which was used to implement the filter was removed (also from the
public interface of the library).

1.2 of lazy_static brings functionality to have no panics in the code,
which is what we try to have.

to also return the index page. This way a user of the library can use
the index page entry right away.

...to report newly created entries, so that we can re-use these new
entries in the library-using code (for example for ID reporting).

The previous iterator was implemented to simply fetch _all_ pathes from
the filesystem, no matter what.
With this implementation, this changes. The iterator now has
functionality to optimize the iteration, if only a subdirectory of the
store is required, for example `$STORE/foo`.
This is done via functionality where the underlying iterator gets
altered.
First of all, the interface was changed to return a `Entries` object,
which itself only covers the libimagstore-internal `PathIterator` type.
This type was changed so that the backend implementation provides an
"PathIterBuilder`, which builds the actual iterator object for the
`PathIterator` type.
The intermediate `StoreIdConstructingIterator` was merged into
`PathIterator` for simplicity.
The `Entries` type got functionality similar to the
`StoreIdIteratorWithStore` type for easier transition to the new API.
This should probably be removed at a later point, though.
As the `walkdir::WalkDir` type is not as nice as it could be, iterators
for two collections in the store could be built like this (untested):
store
.entries()?
.in_collection("foo")
.chain(store.entries()?.in_collection("bar"))
Functionality to exclude subdirectories is not possible with the current
`walkdir::WalkDir` implementation and has to be done during iteration,
with filtering (as usual).
