The block, qcow, and zimage fuzzers all created a SharedMemory and then
converted it into a file; with the new base API changes, this is no
longer supported. Replace the SharedMemory uses with tempfile to fix
the build (this also simplifies the code).

For now, this crate simply re-exports all of sys_util, but it will
be updated to provide new interfaces when needed. This is the
first step to making crosvm not directly depend on sys_util, so
that we can make the interface changes we need without fear of
negatively affecting (i.e. completely breaking) other usages
within chromeos.

Move qcow from being its own crate into a module of the disk crate,
similar to the composite disk module.
This will allow use of qcow from disk and vice versa without introducing
a circular crate dependency.

The new constructors are shorter and omit the bare `None` in the `anon`
call sites which gave no clues to the reader what the effect of that
`None` was. This should improve readability.

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.
extern crate proc_macro;
