Update the schema backend so that the attributes used to represent schema
information are treated correctly according to their definitions.  In
particular, attributeTypes, objectClasses, matchingRules, and ldapSyntaxes are
now properly treated as operational attributes and not returned unless
explicitly requested.  It is possible to override this behavior for backward
compatibility with clients that expect them to always be returned, but this
may be deprecated in the future.
