1. Only listen for peers added and identify events.
2. Remove the old "Limited" check. Peers only show up as "Connected" if
they have non-limited connections.
3. Don't bother listening for new connections directly and/or
connectivity changes. We'll get a new identify event per new connection
regardless.
fixes#546
This removes dependencies on swarm/testing and the blank host.
1. swarm/testing really shouldn't be used at all except for internal
libp2p stuff.
2. The blank host should only be used in _very_ special cases (autonat,
mostly).
* Subscribe to libp2p events to maintain our own Certified Address Book
* Update go version
* Use TestGossipsubStarTopology test instead of new test
* Don't return an error in manageAddrBook
* Return on error while subscribing
* Use null resource manager so that the new IP limit doesn't break tests
* Mod tidy
This will allow us to add more logic around when we split/merge
messages. It will also allow us to build the outgoing rpcs as we go
rather than building one giant rpc and then splitting it.
* add default validator support
* add an implementation for basic seqno as nonce validation
* missing return
