This is adapted from kvm-userspace.  It allows readv to be used with tap when
the host supports it.

This adds virtio-net support.  This is based on the virtio-net driver 
that exists in kvm-userspace.  This also adds a new qemu_sendv_packet 
which virtio-net requires.

Currently tap does not generate signals on I/O; this causes
network latency to be dependent on the timer tick (1ms without
dyntick, guest dependent with dyntick).  By generating a signal
on I/O, we can inform the guest immediately that a packet has
arrived.
