Move public headers to include/net, and leave private headers in net/. Put the virtio headers in include/net/tap.h, removing the multiple copies that existed. Leave include/net/tap.h as the interface for NICs, and net/tap_int.h as the interface for OS-specific parts of the tap backend. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
