libc proper treats mount flags as an unsigned long, which is usually u64,
except when it isn't. When preparing mount flags, use the libc::c_ulong type
instead of u64 to allow for this.
This fixes compiling this file under armv7l.

The comman line help claims that `bcachefs mount <DEV>` without a
mount point will do a dry-run mount - all the steps required to
mount the fs, but without actually doing the final real mount.
Make the code actually do this, rather than complain that you
haven't supplied a mountpoint if you don't provide a mountpoint

This commit enhances mount sub command by allowing it to accept
`OLD_BLKID_UUID=xxx` as the device, enabling whole fs mounting without relying
on colon-separated devices.
Using colon-separated devices in fstab is discouraged due to potential device
reference issues after reboot. Additionally, using `UUID=xxx` in fstab or with
`mount -t bcachefs` is currently infeasible as it depends on blkid, which prior
to v2.39, does not recognize bcachefs. This update enables mounting via fstab
using `OLD_BLKID_UUID=xxx` as obtained from `bcachefs show-super` "External
UUID".

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

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.

- passing of arguments from c -> rust code now works correctly
- 'bcachefs mount' now handles being passed a device or devices

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.
