When printing the error chain, we print the error and then iterate over
the causes. Hence, we have to increase the printed number by one here,
because 0 (zero) is already printed.

This patch fixes a bug where the following code (here pseudocode) did
the wrong thing:
store.entries().in_collection("foo").for_each(||...)
because the `.in_collection()` call for the underlying PathIterator
object did not actually re-build the iterator. It only changed the
contained `PathIterBuilder`, but did not call `.build_iter()` on it to
rebuild the iterator object.
The test added with this patch checks whether the iterator does the
right thing.

This patch changes generate_variants() so that it allows to be passed an
iterator for the modders, which makes it more powerful for passing
references.
This patch removes the magic constant we used when calling
`trace_unwrap_exit()` or `map_err_trace_exit_unwrap()`.
We used to call it with `1` as parameter, where the number was the exit
code to use. Now the implementation of the function does it
automatically (using 1 (one) as exit code).
All calls of these functions were fixed. Thanks to vim this was easy.

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.

This way we alter the underlying iterator for all wiki entries to only
iterate in the "wiki" collection of the store, which results in fewer
disk access because the internal iterator does not yield all pathes from
the store before filtering them.
Code which was used to implement the filter was removed (also from the
public interface of the library).

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)'

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).

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

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.

wrong. This commit adjust the test to check the "filesystem" before
checking the store and fixes the bug.

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.

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.

This patch fixes a bug we did not even hit (yet). It is: When deleting
an Entry from the store, this could potentially leave artifacts in the
cache.
Szenario: An Entry, which was loaded (via `Store::get()` for example),
gets `Store::delete()`ed twice. The first call would work as expected,
but leave the Entry in the Store cache. The second call would then fail,
as the Entry is already removed on the FS, but still in the cache. This
would fail - which is the right thing to do here - but with the wrong
error (with a FileError rather than a FileNotFound error).
This patch fixes this.
First of all, the appropriate `PathBuf` object is calculated in all
cases, as this object is needed to check whether the file is actually
there (which could be the case if the Entry is in the cache and if it is
not).
If the entry is in the cache and is borrowed: error. If not, remove the
entry from the cache. Afterwards the file is deleted on disk.
If the entry is not in the cache, but the file exists, the file is removed.
If the file does not exist: error.
