fixes #595 mutex leak and other minor errors in TCP

fixes #596 POSIX IPC should move away from pipedesc/epdesc
fixes #598 TLS and TCP listeners could support NNG_OPT_LOCADDR
fixes #594 Windows IPC should use "new style" win_io code.
fixes #597 macOS could support PEER PID

This large change set cleans up the IPC support on Windows and
POSIX.  This has the beneficial impact of significantly reducing
the complexity of the code, reducing locking, increasing
concurrency (multiple dial and accepts can be outstanding now),
reducing context switches (we complete thins synchronously now).

While here we have added some missing option support, and fixed a
few more bugs that we found in the TCP code changes from last week.
