Add Java 6's java.io.Console.

This is actually functional, if you're in the mood to "adb shell".

The implementation is based on harmony's, but with the initialization and
native code rewritten, with readPassword responsible for echoing a newline (so
we don't have to play silly tricks with the ECHONL flag), and a vastly
simplified ConsoleReader class. I've also rewritten the documentation.
