src: major API redesign
This patch reworks the initial API. Now it provides functions to: - allocate/release accounting objects. - set/unset/get attributes of accounting objects. - build one netlink message from one accounting object. - parse one netlink message to one accounting object. - print one accounting object into a buffer. Binary layout of nfacct objects are opaque. This is good for extensibility without breaking backward compatibility. Signed-off-by: Pablo Neira Ayuso <>
