We just wanted c sourcefiles out of the top level, not c source
directories.

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

this gets us back down to a single fd for opening block devices, which
means we can use O_EXCL.

not needed with pwritev2(.., RWF_SYNC), and perhaps we can get down to
one fd and then use O_EXCL for block devices.

If io_submit() returns -EAGAIN, that just means the io context is full
and we need to wait for completions - no need to die.

A recent libbcachefs update accidentally committed a change that dropped
the O_DIRECT flag - we definitely didn't want to do that.

We were returning sectors instead of bytes.

We're reading device metadat in mostly sequential order - buffered IO
will be faster than O_DIRECT.

In commit ba1dbafc1fce I reverted 9942fc82d43b, which was a workaround
for an upstream 32bit libaio bug. Oops.

The existing cleanup code would silently cancel disk IO requests, if
somehow the calling code did not wait for completion. This code now
tracks requests and will bug if any are lost.

The shutdown code in d79d57e and b20e160 had a race condition during
shutdown, due to not owning a reference on the associated task_struct
while the associated threads shut themselves down.
Patch over this by taking an appropriate reference.

properly. Manually mark it.
This might be better done by improving the valgrind wrapper for
io_submit.
