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.
