[Colin Walters <walters src gnome org>]

commit 53b4da85dcb49d1fd3dc5e4033e476119653b214
Author: Colin Walters <walters verbum org>

    scanner: Parse annotations for typedefs
    
    * Explicitly check for ast.Alias in annotation pass
    * Add "generic" attribs handling for aliases like docs, introspectable=0
      etc.
