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.

+== NAME
+
+nng_stream_dialer_close - close byte stream dialer
+
+== SYNOPSIS
+
+[source, c]
+----
+#include <nng/nng.h>
+
+void nng_stream_dialer_close(nng_stream_dialer *d);
+----
+
+== DESCRIPTION
+
+The `nng_stream_dialer_close()` function closes the supplied byte stream
+dialer _d_,
+but does not free the underlying resources associated with it.
+
+If any
+xref:nng_stream_dialer_dial.3str.adoc[dial]
+operations using _d_ are
+in progress, they will be terminated with an `NNG_ECLOSED` error condition.
+
+Furthermore any future accesses to the dialer _d_ will also result in
+`NNG_ECLOSED`.
+
+NOTE: This function does not release the memory for the dialer, so the
+application should still free the memory using
+xref:nng_stream_dialer_free.3str.adoc[`nng_stream_dialer_free()`]
+once it is certain that nothing else is using it.
+
+== RETURN VALUES
+
+None.
+
+== ERRORS
+
+None.
