This commit modifies the Unix domain local socket design. Local sockets are built on top of pipes. The Local socket implementation maintained file descriptors to interrupt with the pipes. File descriptors have the bad property that they are valid only while running on the thread within the task that created the local socket.

Local sockets: Local stream sockets had problem of double releasing pipes (both server and client attempt release), which causes wrong pipe pair being closed in multi-client case. Solve by adding per connection instance ID to pipe names. From Jussi Kivilinna (2015-05-12).

Unix domain: Enable logic to clean up the FIFOs underlying stream sockets with those sockets are disconnected. Tehre is still no corresponding clean-up logic in place for Unix domain datagram sockets because the life of the FIFO is not as well known in that case

If a Unix domain socket is non-blocking, then the underlying FIFO should also be opened non-blocking

Unix domain/FIFOs: Fix a race condition between FIFO buffer operations and the opening and closing of FIFOs which necessary when the FIFOs are used to support Unix domain, datagram sockets. The default policy is the deallocate FIFO buffering when the last client closes the pipe. When when used for datagram communicatinos, packets left in the FIFO will be lost. Some like UDP read-ahead is needed: The buffered data in the FIFO needs to be retained until the reader gets a chance to re-open the FIFO. Added an ioctl (PIPEIOC_POLICY) to control the buffer policy. Default (0) is the legacy behavior; Unix domain datagram logic sets the alternative policy so that the packet data persists after the FIFO is closed.
