David Wragg e543bff1ba Don't propagate errors from RelayBroadcast ...

If forwarding of a broadcast frame resulted in a FrameTooBigError, we
would generate an ICMP "fragmentation needed" packet that contravened
RFC1122 on two counts: First, we should not produce a ICMP error
message in response to a broadcast/multicast packet.  Secondly, we
should not produce an IP packet with a broadcast/multicast source IP
address.  (It also gave an ethernet frame with a broadcast source MAC,
which probably contravenes some IEEE spec.)

So when RelayBroadcast gets a FrameTooBigError, it should just drop
the packet.

Futhermore, if we fail to relay a broadcast on one connection, that's
not a good reason to give up entirely - we can proceed to attempt to
relay on the other next hop connections.  Errors other than
FrameTooBigError that propagated upwards were simply logged, so that
logging is moved down into RelayBroadcast.
