Some refactoring is performed in order to always expect the irqfd to be
provided by VirtioInterrupt trait. In case no irqfd is available, we
simply fail initializing the vhost-user device. This allows for further
simplification since we can assume the interrupt will always be
triggered directly by the vhost-user backend without proxying through
the VMM. This allows for complete removal of the dedicated thread for
both block and net.
vhost-user-fs is a bit more complex as it requires the slave request
protocol feature in order to support DAX. That's why we still need the
VMM to interfere and therefore run a dedicated thread for it.

Now all crates use edition = "2018" then the majority of the "extern

This will allow progressive porting of parts of the VMM to using
versioned state. A new trait VersionMapped is introduced with a default
implementation that returns an empty VersionMap to ease implementation.
If a struct is updated the the trait will need to be fully implemented
with VersionMapped::version_map() returning a new VersionMap handling
the change.

By using a Box around the DiskConfig trait, it becomes Sized. For that
reason, we can pass the DiskConfig to the Guest so that it can own it.
This allows for further simplification as the Guest does not need to be
bound to a specific lifetime, which makes things easier.
