Adjust dependencies to use the crosvm-local crates.
The tempfile interface is subtly different use the crosvm implementation
to avoid a dependency on `rand`. Using a temporary directory avoids any
chance of name collision with using rand to generate a string for a
socket name.
Some of the ScmSocket interfaces have changed and needed updating
on both ends.

Originally the VhostBackend trait is designed to take a mutable self,
which causes a common usage pattern Arc<RwLock<T: VhostBackend>>.
This pattern may enforce serialization among multiple threads. So
rename the original VhostBackend as VhostBackendMut, and introduce a
new VhostBackend trait with interior mutability to improve performance
by removing the serialization.

The ring addresses in VringConfigData are host virtual addresses,
and the kernel vhost drivers also expect those addresses as HVA.
So it's wrong to validate/translate those addresses as GPA.

Only basic messages are defined, and the vhost-user spec is also under
development. So feel free to add needed messages.

Implement vhost_kern::Vsock to control the in-kernel vhost-vsock driver.
The implementation is derived from the crosvm project.

The auto-generated vhost binding is small, it would be better
to include it into the vhost crate instead of building another
dedicated crate for it.
