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.

::stf::fs::create_dir_all() takes any ref to `Path`, which is what we
have here, so we can leave out the allocation of a new PathBuf object
here.
Also remove the match by a `if let Some(_)`, which increases the
readability a bit.

With this change, the cache is tested before accessing the filesystem,
which probably increases the speed if the cache has the entry, because
we avoid the slow IO operation.

This fixes a really ugly bug where the in-memory backend for the store
did not remove the entry from the in-memory hashmap on "move", but
simply copied it from the old location to the new one.
That caused tests to fail after the fixes introduced for the
Store::get() function which checked the filesystem and the internal
cache whether an entry exists before the actual "get" operation, because
an old entry would still exist after a move (only in the testcases).

Fixes: 09e8619cf5 ("libimagstore: Move from error-chain to failure")
This changes the implementation of Debug for the FileLockEntry to be
more explanatory of how the entry actually looks like. It does not only
print the path of the store anymore, but also the location of the Entry.
Printing header and content would be still too much, tho.

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.

for safely creating a `String` object from `StoreId` which can be shown
to the user.
Mainly introduced because this is useful for error handling (when
putting a `StoreId` into an error kind, the compiler complains that
`StoreId` does not meet the required trait bounds. But `String` does and
we do not process the ID any further anyways).

The implementation of the in-memory filesystem for testing imag code did
not actually use `HashMap::remove()` when an entry was moved, but
`HashMap::get().cloned()`, which caused the original entry to exist
_after_ the move.
I'm not sure why this did not fail much earlier, but it was clearly
wrong. This commit adjust the test to check the "filesystem" before
checking the store and fixes the bug.

This actually caused tests to fail if there was indeed a file at
/tmp/store/test and the test tried to create a "test" entry in the store.
Do use backend instead to check whether entry actually exists.

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.

This reverts commit a1f0872486995b80216e8a08a2176debdef3752a.
As updating handlebars needs some more involvement, we roll back to the
version we use currently and schedule the update for later.

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).

This patch changes the filesystem-backend implementation of libimagstore
to open files on each read/write rather than holding the file handle in
memory at all times.
Whenever a lot of imag store entries are read into memory, the imag
process may ran out of file descriptors. With this patch applied, a
`Store::get()` call on an entry which is not yet in the store cache
would cause the file to be read, but the FD being dropped after that.
Likewise, a `Store::update()` (which is also called if the imag entry is
dropped) would re-open the file on the filesystem and write the contents
from the imag store cache back to the file.
With this patch, opening hundrets or thousands of imag entries should be
no problem anymore, only the available memory should be a limit then.
