This needed an access() check, like the other uses, instead of exiting
if it can't be read.
Factor out a small common helper for this.

When BCACHEFS_FUSE is disabled or not defined, FUSE section shouldn't

Currently, when no targets are provided for "bcachefs subvolume create" or
"bcachefs subvolume delete", it will exit silently with code 0. Make targets
(arguments) required to solve this problem.
This patch solves issue https://github.com/koverstreet/bcachefs/issues/766.

We don't want users hitting this accidentally, and if needed for some
strange reason (it shouldn't be), it can still be specified via -o.

Migrate now works: there is an inconsequential free space inconsistency
after marking the new superblock (in migrate_superblock), which we're
hacking around with a fsck.

bucket size now takes into account system memory and amount of memory
required to fsck: on very large filesystems it will automatically scale
up bucket size to ensure we can fsck.

Picked armv7l-linux but i686-linux would probably also work. Not sure
which one is more important to check for.

Having a build that uses the actual version of Rust specified in
Cargo.toml should allow us to catch issues with breaking MSRV compat
more easily.

Adds packages for every member of systems from any of the systems. Since
rust-overlay is more or less basically like rustup, we get to just have
all of those targets without having to build quite as much of the
toolchain.

When this environment variable is set, e.g. for some cross compile
setups, the target dir is nested a little further.

This means that the flake can now be built for the following
architectures:
- aarch64-linux
- armv6l-linux
- armv7l-linux
- i686-linux
- powerpc64le-linux
- riscv64-linux
- x86_64-linux
It doesn't mean that it's necessarily going to work perfectly on all of
these architecture and binary cache support is not available for a lot
of them either. But at least it let's you build for them if you want to.

More work to regularize device options, with common command line
parsing - like other options.
This fixes an assortment of little nits: buggyness with the discard
option, device state (and others) can now be specied at device add time,
and is a decent cleanup.

-a is used when called from system to mean "automatic invocation, run
check only if you think you need it".
Since we have self healing and online fsck, we never need run fsck
automatically at boot time.

Implement 'bcachefs data scrub', frontend for
BCH_IOCTL_DATA.BCH_DATA_OP_scrub.
Takes a path to a device, mountpoint, or filesystem uuid. Can be run on
a specific device by passing a device, or if run on a filesystem scrubs
all devices in parallel.
Metadata only scrubbing is supported via -m.
