connman is in charge of pushing messages

Browse Source 
The changes here are dense and subtle, but hopefully all is more explicit
than before.

- CConnman is now in charge of sending data rather than the nodes themselves.
  This is necessary because many decisions need to be made with all nodes in
  mind, and a model that requires the nodes calling up to their manager quickly
  turns to spaghetti.

- The per-node-serializer (ssSend) has been replaced with a (quasi-)const
  send-version. Since the send version for serialization can only change once
  per connection, we now explicitly tag messages with INIT_PROTO_VERSION if
  they are sent before the handshake. With this done, there's no need to lock
  for access to nSendVersion.

  Also, a new stream is used for each message, so there's no need to lock
  during the serialization process.

- This takes care of accounting for optimistic sends, so the
  nOptimisticBytesWritten hack can be removed.

- -dropmessagestest and -fuzzmessagestest have not been preserved, as I suspect
  they haven't been used in years.
