socket property broken

connection.socket property returns an error, since the get_socket method doesn't exist anymore:

{{>>> import mariadb
>>> c=mariadb.connect()
>>> c.socket
Traceback (most recent call last):

fno = self.get_socket()
AttributeError: 'Connection' object has no attribute 'get_socket'}}
