ports listen_socket and telnet_server to POSIX

I had to make some changes to get this to work on Mac and to fix a few regressions it caused in Windows, so please take a fresh look at this diff Dan.

Ibrar, please take a look at the changes from your patch to mine (you may need to diff listen_socket_unittest.h with listen_socket_unittest.cc manually since I moved a bunch of code here).  Some were bugs that I should have caught in review, some were bugs that only got tickled on the Mac, others were just cleanup.  Comments welcome.
