[zeromq-dev] [PATCH] Publisher side filtering

I fixed the patch to handle some corner cases.

Also, the subscription pipe is dropped and re-instantiated on the PUB 
side. This will allow XPUB socket to drop the corresponding 
subscriptions from its map/trie when subscriber shuts down.

The changes are applied to sub-forward branch.

Let me know whether it works as expected.
