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).

We should be able, from the signature of the `generate_variants()`
helper function, to pass a `Vec<&T>` here, so cloning should not be
necessary.

Because this API only errors when write!() errors occur, we can return
the exit code as an error here.
This way the user of the API can immediately exit if there was an IO
error, but the API automatically takes care of the right return value,
returning (exiting) with zero (0) if there was an "Broken pipe" error
and with one (1) otherwise, which is the expected behaviour here.
All calls to that API were changed accordingly.

This removes the feature to be able to override log destinations from
the commandline.
This feature is removed because the --override-config feature from the
runtime already contains this functionality. It is a little more complex
to use, though this is a feature hardly used at all, so I rather go for
less code (less complexity) here than feature bloat.

This feature gives the users of the Runtime API the possibility to check
whether the user wants the ID reporting to be ignored as well (and more
important) to override the default behaviour where the runtime assumes
that if STDOUT is a pipe, it is a pipe to an imag command.
Before, this would not have been possible:
imag contact find Jonas --json | jq 'map(.fullname)'
because the runtime automatically prints the output of the command to
stderr and the touched IDs to stdout.
But now with this change, a user can override this default behaviour and
do:
imag contact --ignore-ids find Jonas --json | jq 'map(.fullname)'

With this patch, IDs can be fetched from the CLI via libimagrt. This
gives us the possibility to automatically handle "stdin provides IDs" in
libimagrt with less boilerplate in the binaries codebases.

This patch adds the id reporting feature to libimagrt::runtime::Runtime,
where processed ("touched") ids can be reported to the Runtime and then
get printed to stdout if stdout is a pipe.
Other output is automatically redirected to stderr if stdout is a pipe
now.
The function already returns `Result<_>`, the only thing that had to be
done was refactoring the code for actually returning an error in that
case.

With this patch, the log level aggregation is abstracted away by using
zero sized types and a macro to implement the whole thing.
This does not alter functionality, but makes the code more readable.

This actually caused an error.
When executing `imag ids --verbose trace` for example, the `imag` binary
got the default value (as in `--verbose info`) supplied from clap. So
far, so good. Problem is that the implementation then forwarded that
flag to `imag-ids`, which resulted in the `--verbose` flag to be passed
_two times_ to `imag-ids`.
Somehow this is really strange, but it does not really matter. First of
all: A default of "Info" is still too high IMO. Default should be
warnings and errors, but no information printed. We like silent tools,
don't we?
Second is that the commandline argument forwarding mechanism of `imag`
is broken and this was a fix which helped debugging of the brokenness,
so this is acutally a step forward in this regard as well.

This feature is required for the `imag` binary. It allows the binary to
use the imag internal logger for logging its own log output.
We need to be able to initialize the logger from an external module (in
all imag modules, the Runtime::new() implementation takes care of this,
but as we cannot use that in the `imag` binary itself, we allow this
method to be public behind a feature flag).

When specifying the `--debug` flag on the commandline, logging was not
enabled. That was because the config file parsing did not consider the
args.
Now, if `--debug` is passed on the CLI, logging is enabled for all
modules and level is set to `debug` for all modules.

The issue was that the handlebars implementation logs as well and if we
use handlebars in the logger implementation that causes recursion which
crashes the program.
With handlebars 1.0.5, there is a feature[0] to disable logging in
handlebars (compiletime) which we use with this patch. The
exception-checking in the log implementation can be removed therefore.

As of rustc 1.26, the `flatten()` method on iterators is preserved by
the rust standard library.
This could cause this code to hard-error some time in the future with
the `flatten()` function actually implemented by the standard library.
Hence we move to use the `Itertools::flatten()` function here
explicitely.
This reverts commit ce0bd9298a.
Pipe magic is removed with this patch.
We remove pipe magic because its implementation in libimagstore is too
complicated and the benefits are too small.
Having this functionality would be really nice, but the cost-benefit
ratio would still be too high.
The implementation in the store would require a rewrite of the internal
caching functionality in the store, plus some functionality to serialize
and deserialize the cache. This is theoretically possible, but as the
store only knows about "StoreEntry" objects, and only the backend knows
of "Entry" (which would be simply de/serializeable), the complexity
increases a _lot_.
Hence, we drop this feature-idea here.
Maybe, at some later point, this functionality will be in imag. The
history of development of this feature is in the history, we just don't
have it merged.
