- even for server initiated streams
- odd  for client initiated streams

This way I will be able to use Pkt.msg_id as real stream_id in go's Conn
because with even / odd scheme there is no possibility for id conflicts
in between two peers.

Reason: there are many failures that appear there also on pristine
master, v1.6.3, v.1.6 with both ZODB4 and ZODB3.

Simply disable to be able to see whether my changes do not introduce new errors.

* origin/master:
  master,client: ignore notifications before complete initialization
  Update comment that was still showing UUIDs instead of node ids
  Remove dead code found by coverage
  Remove some useless unit tests
