compares the returned value with a u64.

We want to be able to run 64-bit ARM kernels using a 32-bit version of
crosvm, to make it more consistent use a u64 to represent
GuestAddress.

These functions are very useful C-style type casting of byte buffers to
structs in a safe manner for types that implement DataInit.

These copy functions are functionally similar to read_from and write_to,
but have stronger guarantees because they are copying to/from concrete
slices. In particular, the volatile access pattern is specified and the
copy operation never returns an error.

This CL adds VM request capabilities to the control socket. These
requests include the basic exit as well as the essential ioeventfd and
irqfd requests. For virtio wayland, the register/unregister device
memory request was added.

The data_model crate is created to hold the DataInit trait. Types
implementing this unsafe trait must guarantee that the type can be
initialized with random data and the resulting object will be valid.
