XPUB socket does not provide all subscriptions

Description

Problem: XPUB socket filters out duplicate subscriptions (deliberate design). However this makes it impossible to do subscription-based intelligence. See http://lists.zeromq.org/pipermail/zeromq-dev/2012-October/018838.html for a use-case.

Solution: make this behaviour configurable with a socket option.
