if the connection is already closed (because the remote closes during
identfiy for example), an exception would be raised which would leave
the connection in limbo, beacuse it would not go through the rest of
internalConnect.
Also, if the connection is already closed, the disconnect event would be
scheduled before the connect event :/
when identify is run on incoming connections, the connmanager tables are
updated too late for incoming connections to properly be handled
this is a quickfix that will eventually need cleaning up
* move pubsub of off switch, pass switch into pubsub
* use join on lpstreams
* properly cleanup up failed peers
* fix tests
* fix peertable hasPeerId
* fix tests
* rework sending, remove helpers from pubsubpeer, unify in broadcast
* further split broadcast into send
* use send where appropriate
* use formatIt
* improve trace

* peer hooks -> events
* peerinfo -> peerid
* include connection direction in event
* check connection status after event
* lock connmanager lookup also when dialling peer
* clean up un-upgraded connection when upgrade fails
* await peer eventing
* remove join/lifetime future from peerinfo
Peerinfo instances are not unique per peer so the lifetime future is
misleading - it fires when a random connection is closed, not the "last"
one
* document switch values
* naming
* peerevent->conneevent
* prefer PeerID in switch api
This avoids ref issues like ref identity and nil
* use existing peerinfo instance if possible
* remove secureCodec
there may be multiple connections per peerinfo with different codecs
* avoid some extra async::
