Add a tool for creating small image files.
Data is written out in a reproducible order, sequentially from the
start of the device.
Metadata is initially written to a temporary device, then after writing
out data, the metadata we want to keep (alloc info is left out by
default) is migrated to the real device.
Then, the image file is trimmed to minimum size and the temporary
metadata device dropped.

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.

This moves the Rust sources out of rust_src/ and into the top level.
Running the bcachefs executable out of the development tree is now:
$ ./target/release/bcachefs command
or
$ cargo run --profile release -- command
instead of "./bcachefs command".
Building and installing is still:
$ make && make install
