fixes #825 TCP public API should use generic setopt/getopt

This changes much of the internal API for TCP option handling, and
includes hooks for some of this in various consumers.  Note that the
consumers still need to have additional work done to complete them,
which will be part of providing public "raw" TLS and WebSocket APIs.

We would also like to finish addressing the call sites of
nni_tcp_listener_start() that assume the sockaddr is modified --
it would be superior to use the NNG_OPT_LOCADDR option.  Thaat will be
addressed in a follow up PR.
