Correctly connects to millipede.

Location keyword on android.cfg isn't supported, EIP corresponding code
has been commented out. I think we should support it in ics-openvpn, so
that we can show the location instead of the server name.

I've updated all opensssl, openvpn, etc. subprojects from rev 813 of
ics-openvpn, and jni too.
