Proper getStackAccessControlContext implementation

Fixed imports and warnings in SecuritySubstitutions
Implemented PrivilegedStack and use FastThreadLocal
Added missing getProtectionDomain method
Recompute contexts from static initializers in runtime
Disallow NO_CONTEXT_SINGLETON in executePrivileged
Work around crash when ProcessPropertiesSupport is missing getExecutable impementation
Provide dummy setters for substituted contexts as their values are constant.
