When bcachefs was a C program that had some functions implemented in
Rust, it was necessary to make a static library containing the Rust
functions available for the C program to link.
Now that bcachefs is a Rust program, that library is no longer needed.
Instead, the Rust executable links in libbachefs.a.
This patch updates the crate structure to reflect that. The command
functions are moved into their own module.
There could be a need to create a "libbachefs-tools" library in the
future that exposes an API for bcachefs functionality to other
userspace programs. That will be a different, external API as opposed to
the previous library functions which were an internal API for the
bcachefs tool itself.

This moves the main() function from C to Rust. It also updates the name
of the Rust package from "bcachefs-rust" to "bcachefs-tools".

The only use for itertools is in parse_mount_options() where we take a
vector, convert it to iterator and then join it. Instead, we can join
the vector directly.

To prevent uncontrolled usage of new rust features, directly or from
dependencies, set a minimum supported Rust version and verify it builds.

Improve the Rust logger by adhering to idiomatic Rust conventions and
incorporating additional logging levels: warn, debug, and trace.

Rust is now required for building the bcachefs tool, and rust code is
now fully integrated with the C codebase - meaning it is possible to
call back and forth.
The mount helper is now a subcommand, 'mount.bcachefs' is now a small
shell wrapper that invokes 'bcachefs mount'.
This will make it easier to start rewriting other subcommands in rust,
and eventually the whole command line interface.
