David Wragg 38f78286c7 Probe whether the kernel has ODP vxlan support 
It's possible to build that kernel with openvswitch, and vxlan, but
without the vport_vxlan module that glues them together.  And at
least one distro has actually done this.

David Wragg c2ad4c5633 Flows 
For fast datapath, the router core will only be invoked upon datapath
misses.  And it needs to yield routing decisions in a form that can be
used to configure the in-kernel datapath.  So here we make the router
core yield FlowOps, which represent operations which actually do
something with a packet.  The router core obtains these in turn from
the Bridge or the Overlay, depending on what it wants to do with
a packet.

For fast datapath, it's critical that the router makes decisions based
only on the required packet header information (as the same header
information will be used when configuring the ODP flow rules).  So we
pass only that information into the router core, in the form of
PacketKeys.

The overall effect is to curry the router core: Rather than taking a
packet and doing something with it, it takes packet header information
and returns a function that does something with a packet.

David Wragg 9956d422f2 Introduce Overlay / sleeve 
This introduces interfaces to represent the packet forwarding
mechanism, and brings all the scattered UDP-related code together into
a single implementation.

This is not a pure refactoring, although much of the code in sleeve.go
has been copied from pre-existing code, and the UDP protocol remains
the same in spirit.  The biggest change is the organization of the
forwarder goroutines (there is now one instead of two, and that
goroutine does a lot of auxiliary work as well as forwarding).
Performance testing between VMs on my laptop suggests that packet
throughput has not gone down, and may even have improved slightly.

indicates that all network interface set-up is complete.

Matthias Radestock fd6d15e712 eliminate misleading flag parsing error 
The standard mflags error reporting produces s.t. like
```
flag provided but not defined: -p
See '/home/weave/weaver --help'.
```
on stderr. This is misleading since the program name is container
local, so not something the user actually invoked.

Fixes #1321.
