Removed the security-manager "validateValue" api. This was

necessitated by changes in the security policy that requires access to
source objects and attribute names to check acces to objects obtained
through attribute access.

New-style class dictionaries are immutable. Changed some class-update
code to use setattr rather thah class-dictionary modifications.
