Jon Bjarni Bjarnason 919f696ad2 extmod/modusocket: Implement optional socket.listen backlog argument.
This follows the CPython change: https://bugs.python.org/issue21455

Socket listen backlog defaults to 2 if not given, based on most bare metal
targets not having many resources for a large backlog.  On UNIX it defaults
to SOMAXCONN or 128, whichever is less.
