fixes #1746 Create a new socket:// transport for socketpair() based connections

This transport only listens, and creates connections when
the application calls setopt on the lister with NNG_OPT_SOCKET_FD,
to pass a file descriptor.  The FD is turned into an nng_stream,
and utilized for SP.  The protocol over the descriptor is identical
to the TCP protocol (not the IPC protocol).

The options for peer information are borrowed from the IPC transport,
as they may be useful for these purposes.

This includes a test suite and full documentation.
