crosvm is switching the import style to use one import per line.
While more verbose, this will greatly reduce the occurence of merge
conflicts going forward.
Note: This is using a nightly feature of rustfmt. So it's a one-off
re-format only. We are considering adding a nightly toolchain to
enable the feature permanently.

This adds a new disk file type next to raw files and qcow images that
represent an indirection to further raw disk files. The disk file
itself is a proto file with references to file paths for other disks to
open and their virtual offsets and lengths.
The intention is to make it easy to assemble a single virtual hard disk
out of several distinct partition files. In the particular case of
Cuttlefish running Android in a VM, this is relevant as the Android
build system distributes partitions as separate raw files. While the
simple solution is to pass each partition as a separate raw disk, some
functionality (like the bootloader) assumes there is a partition table
with multiple distinct partitions on a single disk.
Implementing composite disk support in the VMM bridges this gap through
supporting the general-purpose case of a disk built out of multiple
component files.
If desired, this can be extended to support qcow files to support
unusual configurations like a mixed qcow/raw disk.
Enabled with the "composite-disk" feature.

In Rust 2018 edition, `extern crate` is no longer required for importing
from other crates. Instead of writing:
extern crate dep;
use dep::Thing;
we write:
use dep::Thing;
In this approach, macros are imported individually from the declaring
crate rather than through #[macro_use]. Before:
#[macro_use]
extern crate sys_util;
After:
use sys_util::{debug, error};
The only place that `extern crate` continues to be required is in
importing the compiler's proc_macro API into a procedural macro crate.
This will hopefully be fixed in a future Rust release.
