I can't quite remember what I had intended :(

I think I must have meant 'all_attrs' to be the union of the other two
purely for conviennce.  But on second (or third) thought I can't see why
an app might care for attrs without caring as to whether they are
authenticated or asserted.

(Also, there is the more general problem of what entity authenticated a
given attribute.  But for now I think GSS_Inquire_name() is plenty good
enough, minus the all_attrs argument anyways.)
