This major refactoring of the catalog based shell utilizes the new API macro and
the API Schema as well as rustyline instead of the old GNU readline C API.
The code now has these 3 main components:
* The `Shell` which handles the readline loop via rustyline.
* The shell functions defined via the API macro.
* The `Context` which holds catalog and decoder instances.

This reverts commit a9aa52e6a8.
Because we do not want to use macros for the backup protocol for now.
And because it crashes backup tasks for some unknown reason.
The api macro now supports hyphens in parameter names and
referencing externally defined `Schema`s, so here's an
example.

Decoders read must check if the file is a hardlink and read data from the
corresponding offset if so.

The returned filename should be the one of the file given at the offset, not of
the one the hardlink points to.

`match` is a bit more readable than the if-else chains,
also replace
space_chars.iter().any(|s| c == *s)
with
space_chars.contains(&c)
which is also more readable.

By changing the way shell commands are defined and parsed, this makes it more
straight forward to extend the current functionality.
The readline input is parsed based on the provided command definition and the
given parameters and options are passed to a command specific callback function.
In addition, the provided command definition including its description is used
to generate a help string to display.
The help command shows a list of all supported commands or the help string for
the provided command.
