Daniel Verkamp 96afbc3dd6 vmm_vhost: replace SystemStream with Connection in pub API 
The vmm_vhost::Connection type is now used consistently to represent a
vhost-user connection in the places that previously used a SystemStream
(which is either UnixStream or Tube depending on the platform).

This cleans up the vmm_vhost public API and also keeps more of the
internal vhost-user implementation encapsulated inside the vmm_vhost
library.

The conversion to Connection for unix has also been improved to
propagate the error via TryFrom instead of From, resolving a TODO
comment.

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
