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.

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

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.

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 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.

remount is handled by libc, not the kernel mount procedure, this fixes
remounts. Also sorted the list of flags.

tracing framework is a overengineered for simple mount helper. Add a
few very barebone logging macros to allow configurable verbosity and
colorized output with a small footprint.
