Solaris credentials don't have an fsuid/fsguid field but Linux credentials do. To handle this case the Solaris API is being modestly extended to include the crgetfsuid()/crgetfsgid() helper functions. Addititionally, because the crget*() helpers are implemented identically regardless of HAVE_CRED_STRUCT they have been moved outside the #ifdef to common code. This simplification means we only have one version of the helper to keep to to date.
