Otherwise the directory {a,m,c} times will be modified by the recursive
copy of the directory tree.

The copy_data function takes a start and an end parameter as the range
of bytes to copy, but it was called with a start and a length parameter.
This resulted in incomplete file copies. Fix it by passing the end of
the range instead of the length.

This kernel commit: 65bd442397274347e721a89c2c4882a392bae982 removes
BTREE_ITER_cached from bch2_btree_insert_trans, which causes the
update_inode function to take a long time (~20s). Add this flag back in
the update_inode function.

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.

`bch2_sb_is_encrypted_and_locked()` simply does not check if the fs is
locked. The name is misleading.

We're still having issues with corrupted dumps when we try to dump only
the live part of btree nodes.

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.

Without the single char (with ':' if optarg expected) only the long
argument string would successfully parse.
For example, now "-lasdf" parses the same as "--label asdf"
We need to check when stdin has been closed - otherwise we'll spin
because select() will return immediately.

To avoid expensive version upgrades and downgrades - use the kernel
version of fsck when it's availale and a better match.

Similar to the same option with luks. Ofcourse,
one can simply wrap bcachefs tool with a script and expect,
but this is a nicer way of doing things.

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
