Add many methods to buildsym_compunit

This adds many methods to buildsym_compunit and makes the data members
private.  Essentially the entire buildsym API is now available as a
method on buildsym_compunit.  However, standalone functions are still
provided, as this is what the sybmol readers actually use.
