Learn to compile out vhost-user (net, scsi & upcoming users). Keep it
enabled by default on non-win32, that is assumed to be POSIX. Fail if
trying to enable it on win32.
When trying to make a vhost-user netdev, it gives the following error:
-netdev vhost-user,id=foo,chardev=chr-test: Parameter 'type' expects a netdev backend type
And similar error with the HMP/QMP monitors.
While at it, rename CONFIG_VHOST_NET_TEST CONFIG_VHOST_USER_NET_TEST
since it's a vhost-user specific variable.
