Add a helper to check for close errrors - especially bad file
descriptors, that can be a fun source of heisenbugs.

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.

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.

Add a new source command line argument which specifies the directory
tree that will be copied onto the newly formatted bcachefs filesystem.
This commit also fixes an issue in copy_link where uninitialized data is
copied into the symlink because of a round_up of the buffer size.

Add an environment variable that indicates we prefer to run bcachefs
code in the kernel, not userspace - this is for the test environment
where it's easier to debug kernel code.

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
