Support adding, deleting, and clearing IPv6 addrs.

- Provide a function to add and delete IPv4/IPv6 addresses
  using netlink.
- Provide a function that clears all IP addresses on an
  interface that can be used by netd.

Also, a couple of cleanups:

- Update the header file to match reality, and include the
  header file in the implementation. Also fix a caller that
  has an incorrect method signature.
- Fix whitespace in Android.mk.
