Jython: rpyc Server doesn't report correct listening port when set to 0 #156

This seems to just be a quirk in Jython's socket implementation (see jython issue 1806):

>>> import socket
>>> s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
>>> s.bind(("localhost", 0))
>>> s.settimeout(0.5)
>>> s.getsockname()
('', 0)

But, if we add a call to s.listen, the next s.getsockname() returns the correct info:

>>> s.listen(1)
>>> s.getsockname()
('', 57581)

I'm not sure how much you care about Jython suport, but it seems like it would pretty safe to update self.port in Server.start after calling listen.

Thanks! Fix implemented as understood from your description (better late than never). Give me a shout if the problem is not solved.

Best, Thomas
