Add support for TCP_DEFER_ACCEPT

"man tcp" on Linux says:

TCP_DEFER_ACCEPT

Allows a listener to be awakened only when data arrives on the  socket.  Takes
an integer value (seconds), this can bound the maximum number of attempts TCP
will make to complete the connection. This option should not be used in code
intended to be portable.

This might reduce the 139/445 forks a bit on high-load servers
