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

Mount is checking for and adding encryption keys using the logon key
type instead of the user key type. This was causing it to not be able to
unlock volumes on its own, and ask for a passphrase on already unlocked
volumes.

read_password_from_tty doesn't have a fallback if input is a pipe.
This makes scripting and integration testing harder.
Noticed while updating our nixos integration test.

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 implements BtreeNodeIter, and adds it to cmd_list.rs - the next
step in having a full replacement for cmd_list.c

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

Implement a rust equivalent to bkey_s_c, which uses references with the
correct lifetimes: now cmd_list.rs doesn't need unsafe.

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
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
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.
