This moves the Rust sources out of rust_src/ and into the top level.
Running the bcachefs executable out of the development tree is now:
$ ./target/release/bcachefs command
or
$ cargo run --profile release -- command
instead of "./bcachefs command".
Building and installing is still:
$ make && make install

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

In an effort to rewrite `bch2_read_super` from C to Rust,
it is neccessary to have `opt_get!` macro defined, and some
FMODE_* consts (defined as macro in `include/linux/blkdev.h`)
defined as Rust const.
Bindgen is currently unable to exapnd C functional macro [1],
this this commit use the workaround as introduced in [2].

This implements opt_set!(), which works exactly the same as the C
version and allows filesystem options to be specified in Rust code.

This is a _very_ preliminary rewrite of the cmd_list tool in rust, which
is intended to be a testing ground for a safe interface in Rust to the
core btree interface. This adds rust wrappers for:
bch_fs: provides bch2_fs_open(), bch2_fs_stop
btree_trans: provides bch2_trans_init(), bch2_trans_exit()
btree_iter: provides peek, peek_and_restart, advance
bch_errcode: implements Display (wraps bch2_err_str())
bpos: implements Ord (wraps bpos_cmp())
bkey_s_c: implements Display (wraps bch2_bkey_val_to_text())
and other assorted types.

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.

update makefile to output shared library and rust build
fix default.nix to properly get the binary name for `ln`ing - move binary to main.rs
add rustfmt and gitignore files
move build.rs file into bch_bindgen for reuse between projects
add outputs to nix flake and checks
add mount.toml to makefile
