2dcb632405 qcow: Set refcounts for initial clusters.
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.

d1ab493672 fix some clippy errors that are default deny
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
