This patchset expands the KVP (Key Value Pair) functionality to
implement the mechanism to GET/SET IP addresses in the guest. This
functionality is used in Windows Server 2012 to implement VM
replication functionality. The way IP configuration information
is managed is distro specific. Based on the feedback I have gotten
from Olaf, Greg, Steve, Ben and Mairus, I have chosen to seperate
distro specific code from this patch-set. Most of the GET operation
can be implemented in a way that is completely distro independent and
I have implemented that as such and is included in this patch-set.
Some of the attributes that can only be fetched in a distro
dependent way as well the mechanism for configuring an interface
(the SET operation) that is clearly distro specific is to be
implemented via external scripts that will be invoked via the KVP
code. We define here the interface to these scripts.

Adding support for IP injection resulted in some changes to the
protocol between the user level daemon and the kernel driver.
These changes have been implemented in way that would retain
compatibility with older daemons. I would like to thank Olaf and
Greg for pointing out the compatibility issue.

Due to this being the middle of the merge window, I will not be able to
look at this until after 3.6-rc1 is out.
