Continued revamping of libsmbclient.

- James suggested using gcc's "deprecated" attribute to mark the context
  structure fields to generate warnings.  This creates a scenario with the
  best of all worlds.  I'm able to move to an organization that more easily
  allows future enhancements, while avoiding any mandatory changes by
  applications.  Thanks, James!

- Updated WHATSNEW.txt so that it accurately reflects the current state of
  affairs.
