Bryan Boreham d2f0287fa3 Handle range wrap-around when checking for allocations 
Ring wraps around at zero but Space doesn't know about this, so we
have to normalise ranges coming out of Ring.  In turn we may need to
split one range into two, across the end of the Ring.

Bryan Boreham 39ac1a0037 Collect existing weave addresses at start-up, to avoid a race when 
doing it from the script

Note we need to run weaver in the host pid namespace, so it can search
for existing container IPs. Also now we are firing off sub-processes
it's better to not be PID 1 so Linux doesn't expect us to reap zombies.

Martynas Pumputis 8569cbd4a3 Force transferring of IPAM ranges in a case of Shutdown 
If no peer for transfer is found, we transfer them to
mesh.UnknownPeerName to notify the ring update tracker.

Makes the awsvpc tracker to remove local entries from
the VPC route table when the last peer calls "weave reset".

Martynas Pumputis 9fc7be83c8 Create a Tracker when starting the router 
The tracker's HandleUpdate method is called by the ring update routines.

In addition, we add a dummy overlay for AWSVPC to make `weave (status|
report)` to produce reasonable reports which includes AWS hosts
connection state.

of the function first.
Also bail out if there is no persisted ring, since persisted 'owned'
data isn't meaningful in that state.
