New Android release after adding AES-GCM, IPv6-in-IPv4 and using kernel-netlink

libipsec now supports AES-GCM, IPv6 tunnels over IPv4 are supported,
native x86 libraries are built (requires a new Vstr build script).
Also, the existing kernel-netlink plugin now provides the kernel-net
implementation, which should be more stable in case multiple interfaces
are up and have IP addresses installed on them.
