Fix data loss for PUB/SUB and unidirectional transports (LIBZMQ-268)

With the introduction of subscription forwarding, the first message
sent on a PUB socket using a unidirectional transport (e.g. PGM) is
always lost due to the "subscribe to all" being done asynchronously.
This patch fixes the problem and also refactors the code to have a
single point where the "subscribe to all" is performed.
