start of a patch to fix

This patch starts to fix this bug.  There are a few problems that need to be
resolved to allow container-based VMs to hook to ns-3 devices that do not
support bridging (the TapDevice::USE_LOCAL mode).

1) Node::RegisterProtocolHandler should not associate SupportsSendFrom() with
setting promiscuous receive hooks
2) We should have a base class NetDevice::SetAddress() method so that the
TapBridge can overwrite the ns-3-assigned Mac address at runtime
3) The TapBridge should unregister protocol handlers on the underlying device
before registering itself as a handler.  This prevents duplicate Arp replies. 
This is not implemented in the patch (see an XXX there)

Once these three things are fixed, I think it will work
