vhost does not have to be supported only if KVM is present, in fact
vhost-user does not even need any kind of kernel support.  This series
changes this.  The rationale is that, when vhost-user-test.c will be
converted to qgraph, it will be able to test vhost-user support
for virtio-mmio backend even on x86.

v1->v2: use vhost_types.h for portability to the BSDs.

Paolo Bonzini (5):
  vhost-net: move stubs to a separate file
  vhost-net-user: add stubs for when no virtio-net device is present
  vhost: restrict Linux dependency to kernel vhost
  vhost-net: compile it on all targets that have virtio-net.
  vhost-net: revamp configure logic
