Separated out of CL:1513058 to make it possible to land parts
individually while the affected crate has no other significant CLs
pending. This avoids repeatedly introducing non-textual conflicts with
new code that adds `use` statements.

This is an easy step toward adopting 2018 edition eventually, and will
make any future CL that sets `edition = "2018"` this much smaller.
The module system changes in Rust 2018 are described here:
https://doc.rust-lang.org/edition-guide/rust-2018/module-system/path-clarity.html
Generated by running:
cargo fix --edition --all
in each workspace, followed by bin/fmt.

The description method is deprecated and its signature forces less
helpful error messages than what Display can provide.

The Condvar wrapper exposed by this change is analogous to the Mutex
wrapper in this crate. Instead of a Result being returned in the case of
a poisoned Mutex, a panic is triggered.

Split sub-crates under crosvm root directory into several independent
workspaces for adding ebuild files for those crates.
data_model and sys_util could only be built by emerge after creating
their ebuilds.

This CL adds a crate `sync` containing a type sync::Mutex which wraps
the standard library Mutex and mirrors the same methods, except that
they panic where the standard library would return a PoisonError. This
API codifies our error handling strategy around poisoned mutexes in
crosvm.
- Crosvm releases are built with panic=abort so poisoning never occurs.
A panic while a mutex is held (or ever) takes down the entire process.
Thus we would like for code not to have to consider the possibility of
poison.
- We could ask developers to always write `.lock().unwrap()` on a
standard library mutex. However, we would like to stigmatize the use
of unwrap. It is confusing to permit unwrap but only on mutex lock
results. During code review it may not always be obvious whether a
particular unwrap is unwrapping a mutex lock result or a different
error that should be handled in a more principled way.
Developers should feel free to use sync::Mutex anywhere in crosvm that
they would otherwise be using std::sync::Mutex.
