Implement the Java 6 NetworkInterface/InterfaceAddress functionality.

The Java bits are based on harmony's code (though only the bit that pulls
out the sub-interfaces is copied verbatim), but the native side is new
code, continuing our previous plan of (a) doing the least possible work
on the native side and (b) using the BSD getifaddrs(3) interface as our
portability layer.

This patch also updates our NetworkInterfaceTest to be the latest code
from harmony's java6 branch.

We pass all the harmony and jtreg tests, and visual inspection shows that
the untested (and hard to test) bits -- such as prefix length and hardware
address -- are correct.
