Add misc android/base/ helper classes.

This patch adds a few new helper classes under android/base/ that
will be used by future patches.

- Add a 'clear' method to String class.

- Add StringFormat() function to generated String instances
  from formatted string input, and StringAppendFormat() to
  append some to an existing instance.

- Add ScopedFd to implement a scoped file descriptor wrapper.

- Add ScopedHandle to implement a scoped Win32 HANDLE wrapper.
