This exports a new C API to resize a disk image. The new function is
intended to only expand (increase in size) to avoid accidentally
truncating user data due to bugs elsewhere.

We updated the production toolchain from 1.30 to 1.31 in CL:1366446.
This CL does the same upgrade for the local developer toolchain and
Kokoro.
The relevant changes are in rust-toolchain and kokoro/Dockerfile.
The rest are from rustfmt.
TEST=cargo fmt --all -- --check
TEST=as described in kokoro/README.md

The `convert_to_*` functions take ownership of the passed FDs even
though they should not according to the function's contract. This change
clones the passed FDs so that the caller can retain ownership of its
FDs.
This change also wraps most of the implementations in catch_unwind so
that panics do not unwind past FFI boundaries, which is undefined
behavior.

This will be used in vm_concierge's ExportDiskImage function in order to
allow a minimal qcow2 image to be written on the fly (containing only
the required clusters in a tightly-packed image file). It also allows
future flexibility to change the underlying disk image file format while
still exporting qcow2 images (e.g. via `vmc export`).
For testing, add a qcow_img `convert` command, which can convert
between raw and qcow2 as both source and destination.
BUG=None
TEST=Use qcow_img to convert a raw image to qcow2 and back and verify
its contents are the same as the original.

All qcow clusters need to have their refcounts set. Add a `new` method
to `Qcowfile` and use it instead of just headers from the library.
The new method will loop over the initial clusters and initialize their
refcounts.
Add a `create_qcow2` option to the main executable so there is a way to
test image creation that doesn't require DBUS and Concierge.
BUG=none
TEST='crosvm create_qcow2 /tmp/file.qcow2 1000000'
'qemu-img check /tmp/file.qcow2'
no errors reported.

Clippy only has 6 lints that are defaulted to deny, which this CL fixes.
The first step to running clippy and establishing our own set of default
deny lints, is to ensure we aren't running afoul of the most common
deny lints.
BUG=None
TEST=cargo clippy --all

Also fix extern "C" for the qcow_utils header.
