Add options to set ports on weaver command line
...
This commit adds two command line options, intended to allow multiple
instances of weave to run without container separation between them.
* -port=PORT makes weave bind to port PORT (an integer). Without the
option, the default value (6783) is used.
* -httpaddr=ADDRESS makes weave bind its control interface to
a different address. For instance "127.0.0.1:6784" can be used to
bind to localhost only. An absent address element makes it bind to
all interfaces. ":6784" is the default. An empty string
can be used to disable the control interface.

make connection heartbeating independent of periodic gossip
...
This was a convenient but rather suspect coupling. In particular, it
will break if the period gossip logic changes s.t. it no longer sends
gossip on all connections every interval.

eliminate AddConnection/RemoveConnection race
...
We were invoking AddConnection in a separate goroutine, and this could
result in RemoveConnection getting invoked first, resulting in bogus
entries in our connection map, which would effectively prevent
connectivity to the other peer until the stale entry got removed
through a lost tie break. And if, per chance, the remote end ran into
exactly the same race condition, then connectivity between that peer
and ourself was broken permanently.
Hitting this race condition required a combination of a) no UDP
heartbeat being received for HeartbeatTimeout(30s) - this causes the
actorLoop to terminate and RemoveConnection to be invoked, and b) the
AddConnection invocation getting delayed for at least that long.

optimise broadcast route calculation
...
...by obtaining our connection set just once. This also guards against
potential locking issues, since we no longer obtain the required
lock on our local peer while holding a lock on Peers.
Note that this change means the connection list can be out of date by
the time we enter Peers.ForEach. However, previously it was possible
for the list to change for each peer we are iterating over. So it's
just a different flavour of out-of-dateness.

We don't really care about the performance aspect of this, but using
struct{}{} values is in some way canonical since it means the
representation carries no redundant information.
