This patch changes the Entries::in_collection() interface to return a
Result<()>. This is needed because the fs backend implementation should
be able to check whether a directory actually exists whenever we change
the iterator.
If the implementation detects that the directory does not exist, we can
fail early and error out.
All usages of the interface are adapted by the patch as well.

With this patch we move the codebase to Rust-2018.
The diff was generated by executing
cargo fix --all --all-features --edition
on the codebase.

Because the code was so complex before, we had to create an object and
then cast that object into a `StoreId` rather than just creating a
`StoreId` object right away.
With this patch, we're using the code-generation approach to generate a
function that creates a `StoreId` object based on the name of the
current module. That's way easier and error handling was also improved
by the switch to the new implementation.
The patch also includes a rewrite of all usages of ModuleEntryPath and
changes them to `module_path::new_id()` calls.

The bug was that we compared the variable with itself, but one time to
lowercase and one time not, so it was always false.

We create a sha1 over the path of the file and the Message-ID of the
mail itself.
The file name is not constant with mail files, because flags are encoded
in the filename. The path is also not constant with mail files, because
they can be moved between boxes.
This approach is not yet the best one, but better than before.

This merge solved a _LOT_ of conflicts and was a rather complicated one,
as parts of the conflict-resolution involved rewriting of half the
stuff.
This merge commit fixes all the things so a `cargo check --all`
succeeds, but I did not yet check whether tests run without failure.
