fixes #872 create unified nng_stream API

This is a major change, and includes changes to use a polymorphic
stream API for all transports.  There have been related bugs fixed
along the way.  Additionally the man pages have changed.

The old non-polymorphic APIs are removed now.  This is a breaking
change, but the old APIs were never part of any released public API.
