getaddrinfo may return the wrong address

[GoogleCodeExporter]

Ipv6 is enabled in my machine and getaddrinfo returns the ipv6 address first. 
Since it is a valid address the socket function does not fail but the connect 
function fails because the jabber server is not listening on ipv6. As a result, 
the library does not attempt to connect on the ipv4 address and fails to 
connect to the server. The library try the second address only if the socket 
function fails.
