Overlapped I/O engine for Nsock on Windows #148

Nsock on Windows is still stuck using select(), which has performance limitations. Overlapped I/O is one option for handling many thousands of concurrent connections efficiently.

Here is another useful link on the subject: http://tinyclouds.org/iocp-links.html
I think the difficulty will be to make it fit within nsock reactor model...

Poll() is available on windows and can handle many FDs, though not as efficiently as the advanced APIs mentioned here.

IOCP Nsock engine was added as part of GSOC 2016 by @Tudor-Coman
