Initially the licensing was just Apache-2.0. This patch changes
the licensing to dual license Apache-2.0 OR BSD-3-Clause

When set_user_memory_region was moved to hypervisor crate, it was turned
into a safe function that wrapped around an unsafe call. All but one
call site had the safety statements removed. But safety statement was
not moved inside the wrapper function.
Add the safety statement back to help reasoning in the future. Also
remove that one last instance where the safety statement is not needed .
No functional change.

Implement the vCPU state getter and setter separately from the initial
KVM Hypervisor trait implementation, mostly for readability purposes.

For each of the traits we are defining kvm related structures
and add the trait implementation to the structs. For more information
please see the kvm-ioctls and kvm-bindings crate.
This is a standalone implementation that does not include the switch of
the Cloud-Hypervisor vmm and arch crates to it.

As the only hypervisor that Cloud-Hypervisor supports is KVM, the
Hypervisor trait accomodates for the upcoming KVM implementation.
This trait will be instanciated at build time through hypervisor
specific features, i.e. it's not aiming at run-time selection of
hypervisors for Cloud-Hypervisor.

This VM trait should be implemented by each underlying hypervisor.
Previously created hypervisor object should create the VM based on
already selected hypervisor. This is just the trait definition. For each
of supported hypervisor we need to implement the trait. Later we will
implement this trait for KVM and then Microsoft Hyper-V.

This Vcpu trait should be implemented by each underlying hypervisor.
Previously created hypervisor object should create the VM based on
already selected hypervisor and Vm object should create this vcpu
object based on same hyperviosr. Each of this object should be
referenced by trait object i.e <dyn Vcpu>.

The purpose of this trait is to add support for other hypervisors than
KVM, like e.g. Microsoft Hyper-V.
Further commits will define additional hypervisor related traits like
Vcpu and Vm. Each of the supported hypervisor will need to implement all
traits defined from the hypervisor crate.
