Historically the Cloud Hypervisor coding style has been to ensure that
all imports are ordered and placed in a single group. Unfortunately
cargo fmt has no support for ensuring that all imports are in a single
group so if whitespace lines were added as part of the import statements
then they would only be odered correctly in the group.
By adopting "group_imports="StdExternalCrate" we can enforce a style
where imports are placed in at most three groups for std, external
crates and the crate itself. Choosing a style enforceable by the tooling
reduces the reviewer burden.

The largest possible PTM response is only 16 bytes. Size the output
buffer correctly.
In the socket read function, rely on the caller to provide a
sufficiently large buffer. That eliminates another large stack variable.
In total this saves almost 8KB stack space.
