The datapath interface defined in odp-netlink.h needs some extensions
that are platform dependent. Some examples are the name of the communication
device on Windows and a set of commands that are specific to Windows.
In this change we define a datapath-windows/include/OvsDpInterfaceExt.h
to include any platform specific interface extensions.
OvsDpInterfaceExt.h is in turn included in odp-netlink.h ONLY for _WIN32.
This approach was chosen to avoid including OvsDpInterfaceExt.h directly
although the latter approach is as good as the former.
Also, we define three ioctls in OvsDpInterfaceExt.h:
read: provides an output buffer (mimics a recv)
write: provides an input buffer (mimics a send)
transact: provides an input and optionally an output buffer.
(mimics a send followed by recv)
