As release fixes, I'd like to merge these netlink detection support fixes for
old kernels and fix and tonight send also add lapi/if_addr.h with IFA_FLAGS
(to fix compilation on some old kernels).

Last thing which I'd like is to state which version we support in this release
(as document to doc/ and wiki). After release we can discuss which support we
can drop.

Kind regards,
Petr
