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.

Add a crate for deserializing command-line options given as key-values.
This crate leverages serde to deserialize key-value argument strings (a
commonly used pattern in crosvm) into configuration structures. This
will allow us to remove a big part of the manual parsing currently done
in `main.rs`, will provide consistent arguments to the `crosvm run` and
`crosvm device` commands, and results in more precise error reporting.
The use of serde will also allow us to similarly deserialize
configuration structures from configuration files with very little extra
code involved.
As explained in the crate's documentation, its main entry point is a
`from_key_values` function that allows a build a struct implementing
serde's `Deserialize` trait from a key/values string.
In order to integrate transparently with `argh`, there is also a
`FromKeyValue` derive macro that automatically implements `FromArgValue`
for structs deriving from it.
