net: add receive_raw parameter to qemu_new_vlan_client()

Trivial patch to allow supplying a receive_raw function.

A future cleanup should combine this function pointer parameters into a
table.

net: add a client type code

This is so as to allow APIs which operate on specific client types
without having to add a function table entry which is only implemented
by a single client type.

net: allow NICs to be connected to netdevs

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.

net: Provide VLAN client lookup helper

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.

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

This, apparently, is the style we prefer - all VLANClientState
should be an argument to qemu_new_vlan_client().

net: re-name vc->fd_read() to vc->receive()

VLANClientState's fd_read() handler doesn't read from file
descriptors, it adds a buffer to the client's receive queue.

Re-name the handlers to make things a little less confusing.

net: pass VLANClientState* as first arg to receive handlers

Give static type checking a chance to catch errors.

net: add return value to packet receive handler

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

Drop them to make qemu build on OpenSolaris.

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...
