Subject: Add support for ExtensionAdditionGroup notation in nested types as
 well

In the previous version support for ExtensionAdditionGroups (i.e [[...]])
was added but it did not handle the occurence of the notation in nested types.
Now this is handled as well and the support is hopefully complete.
Also cleanup of warnings for obsolete guard functions in test suites.
