This patch adds support for directional links in libimagentrylink.
A directional link is added to the same header as the "internal" links,
which are unidirectional.
The "outgoing" link is added in "links.to", the "incoming" links are
added to "links.from".
This way we can always traverse all linkage. The `Linkable::links()`
method is changed to always return _all_ link.
The `Link` type was extended for notions of "to" and "from" links.
Also adds testing.

This patch removes the annotateable linking feature from libimagentrylink.
It was not used anyways.
Also, this patch rewrites the complete linking code to use the
toml-query "typed" feature rather than constructing everything by
itself.
This removes a lot of unmaintainable boilerplate code.

With this patch, the libimagentrylink library interface gets renamed.
The trait gets renamed to the more descriptive name "Linkable", the
functions get renamed to not contain any notion of "internal" anymore.
This patch also adapts the whole source tree for the new libimagentrylink
interface, also renaming variables to not contain "_internal_" anymore.

Because we need to catch errors that are caused by a borken pipe when
writing to stdout (for example), this patch changes the interface of the
Viewer trait to return an error enum that can be used to check whether
an IO error happened.
The calling code can then decide whether to ignore a broken pipe error
or whether to handle it properly.

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.

This function needs to be removed because of the following problem:
When linking from one entry to another, and then removing the link in
the first entry with ::set_internal_links(vec![]), we end up with a
dangling link in the second entry, because the ::set_internal_links()
function does not take care of removing the links in the "other"
entries.
Actually, it is not even able to do so, because it would need to
`Store::get()` those entries, but it does not have access to the store.
Adding a `store` parameter to the function would be possible, but only
increase its complexity unnecessarily. This is why I opt for removing
this function (which is btw not used once in the whole imag codebase).

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.

This function can be used to override the basepath setting from the
header of the entry so that another basepath is used for looking
up/constructing the actual filepath.
This might come in handy at some point.

The setting in the header should reflect the name of the setting in the
configuration file, for a better user experience.

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 beta compiler reports duplicated input:
error: the item `IntoValues` is imported redundantly
--> lib/entry/libimagentrylink/src/internal.rs:398:13
|
36 | use self::iter::IntoValues;
| ---------------------- the item `IntoValues` is already imported here
...
398 | use internal::iter::IntoValues;
| ^^^^^^^^^^^^^^^^^^^^^^^^^^
|
so we fix this here.
Other imports were fixed as well.
