Fixes corba reconnections of buffer ports

Since the server was not cached, reconnects confused the connection
logic. We're now caching the buffer servers, similar to the
expressions/data objects. Also improved some of the corba data flow
and added some debug statements here and there.

What does not seem to behave 'transparently' is p->connection->disconnect()
where p is a proxy to a port. It should disconnect all the ports,
but it is somehow picked up again and reused in a next connect. One can work
around by using p->disconnect() to disconnect the port directly. For buffers,
this means the difference between using the latest data (new connection
created), or keeping the buffer alive.

There is certainly some room for improvement but at the functional
level, it behaves ok now.
