Update the resiter dependency, so we can remove our implementation of
the `IterInnerOkOrElse` extension trait.

This reverts commit d810b63886f4006d01bca894982bbc867616f37c.
As resiter v0.4.0 does provide this extension now, we don't need it in
the codebase anymore.
This merge includes the first batch of "no-exit()-call" patches.
With this patchset, we do not exit() anywhere in the core binaries
anymore, but propagate errors up to the main() function, where they are
returned.

This extension traits help transforming Result<Option<T>, E> to
Result<T, E> or transforming an iterator over the former type to an
iterator over the latter type.
Should be moved to resiter of course, but we need to implement this
first.

This merge pulls in the changes that Leon developed over the course of
the last months which change the binaries to actually be libraries with
a _very_ minimal binary surface. This enables us to actually generate
commandline completion scripts with clap without doing any fancy
file-include magic in a build.rs script.
From the original request-pull message (Mon, 24 Jun 2019 21:48:51 +0200):
> This patch is yet another attempt at bringing CLI completion to this
> workspace project. The details are explained in the commit message.
>
> Advantages of this approach include:
> - Use of standard dependency management features (`cargo install`
> compatible)
> - Exposing further "binary" business logic to other Rust crates as a
> library
> - (Possibly) hard linking the "binary" into the main imag binary, so
> only one binary needs to be shipped. This should improve startup time,
> and the Runtime instance could even be reused. I'd favor this
> approach, while making it all configurable via features and still
> searching the $PATH to allow bash-scripts etc. to provide imag
> subcommands.

Some patches were added by me before the merge, because Leon did not
check whether the tests still work (just minimal adjustments, see the
log).
Also, one change was made to the final patchset send by Leon, which was
a fixup of the Copyright date in bin/core/imag/build.rs. This change
does not appear in the commit logs because it was just bumping the year
from 2018 to 2019 in the Copyright header. This was acked by Leon in a
private conversation.
