Do the per-parent-key tracking within `libelektra-kdb`, but with meta keys.

Essentially the same approach as above, but instead of deep-duping, we add the original value

The tracking itself would be done within the `ks*` and `key*` methods, after checking if it is enabled.
It would also transparently work for meta-data, as meta-data itself is implemented as a keyset with keys.

We already store which keys have been returned by `kdbGet` for each backend within KDB.
Currently, however, this is not a deep duplication, as we are returning the keys from `backendData->keys` directly.
This means we can not detect changes to the values or meta-data of keys right now.
This means we can not detect changes to the values or metadata of keys right now.
We can, however, rely on this for detecting removed and added keys in its current form.

If we don't want to deep-dup it, we'd need to do something different to detect which keys have been modified.
One possibility would be to add meta-data within the `key` functions (e.g. `meta:/elektra/original`), but that would violate the `libelektra-core` must be minimal constraint.
One possibility would be to add metadata within the `key` functions (e.g. `meta:/elektra/original`), but that would violate the `libelektra-core` must be minimal constraint.

There is already [another decision](internal_cache.md) which discusses adding general copy-on-write semantics to Elektra.
We could use this together with `backendData->keys` deep-duped to do memory efficient change tracking.

This is problematic, as plugins may store the result of `kdbGet` and use the stored data in the following `kdbSet` to calculate a changeset.
Plugins have to do this, as there isn't any other Elektra-provided mechanism currently to do change tracking for them.

Note, that erroneous behaviour only occurs if plugins are used globally, i.e. as `notification-send` hook plugins.
If they are mounted for specific backends (via `kdb mount`), this behaviour will not occur as plugins from different backends are isolated.

The following example will demonstrate the problematic sequence as real, runnable code.

These both plugins just serve as a general demonstration, and there may be more plugins that do change tracking this way.

In a separated branch we rewrote the whole backend system.
With this new backend system, backends are now also plugins, allowing backends also to be non-file-based, e.g., using databases.
The main purpose of this release is to give a last stable release before master gets disrupted with a huge change set.
