bcachefs, along with a warning regarding snapshots.

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.

so that libbcachefs.so builds in a reproducible way
in spite of non-deterministic filesystem readdir order.
See https://reproducible-builds.org/ for why this is good.
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.

Hi
Here I'm sending a small compile fix for bcachefs-tools.
Without this patch, I get this error:
cargo build --release --manifest-path rust-src/Cargo.toml

It is not declared in linux/futex.h, so we need to include urcu/futex.h

For systems without working rust/llvm/bindgen, add an option for
building without Rust. This will be less of an option in the future, as
more code gets rewritten in Rust.

A recent libbcachefs update accidentally committed a change that dropped

Add a new make target to build an rpm. This uses rpmbuild --build-in-place,
so no SRPM is created.
Also clean up the specfile to remove manually-added Requires: that will
be auto-generated, add a couple new BuildRequires: and use macros for
file locations.

- migrate readmes to markdown for improved formatting
- The main binary now requires the Rust toolchain, so make note of it
in the build instructions.
