The original Berkeley paper on sockets by Bill Joy 
http://maibriz.de/unix/ultrix/_root/net.pdf
defined OOB support for all streams sockets.
However, this support was never added to AF_UNIX
streams sockets, probably because it was not needed.

With several containers running on the same host, AF_UNIX sockets
are being used instead of TCP sockets because they are efficient.
Papers have been published that show the performance benefit of using
AF_UNIX sockets and mention lack of OOB support.
https://www.usenix.org/system/files/conference/atc15/atc15-paper-dietz.pdf
Products are also being built that require OOB support for AF_UNIX sockets.

This patch adds OOB support to AF_UNIX stream sockets. The semantics
are same as that of TCP.
