Introduce a 'peer' member to VLANClientState as an alternative
to a vlan. The idea being that packets are transfered directly
from peer clients rather than going through a vlan.

Introduce qemu_find_vlan_client_by_name for VLANClientState lookup based
on VLAN ID and client name. This is useful for monitor commands.

xen nic: check tx queue after connect.

Needed for savevm/loadvm + migration: In that case the queue might
already have packets on (re-)connect. The guest wouldn't notify us
because notifications are only sent when stuffing a packet into an
empty queue.

This allows us to handle queue full conditions rather than dropping
the packet on the floor.

net: add fd_readv() handler to qemu_new_vlan_client() args

This, apparently, is the style we prefer - all VLANClientState

xen: add net backend driver. (Gerd Hoffmann)

This patch adds a network interface backend driver to qemu. It is a pure
userspace implemention using the gntdev interface. It uses "qnet" as
backend name in xenstore so it doesn't interfere with the netback
backend (aka "vnif").

The network backend is hooked into the corrosponding qemu vlan, i.e.
vif 0 is hooked into vlan 0. To make the packages actually arrive
somewhere you additionally have to link the vlan to the outside world
using the usual qemu command line options such as "-net tap,...".
