core (xmpp), plugin android: fixed DNS, SRV handling on Android: Android doesn't have a "/etc/resolv.conf" that Twisted expect. As a result, SRV records can't be checked correctly on connection. To work around that, DNS servers used on Android are checked when necessary (on Android plugin startup and on connectivity change), using some hacks, and Twisted is patched to use them.
