C++ Annotations Svn-unmaintained

and extensions to C++. These will be covered by the C++ Annotations in the
coming months, resulting in version 8.0.0 of the C++ Annotations. Various new
sections and possibly a new chapter will be added. The new sections can be
found looking for csect, csub and cincludefile in the top-level .yo files. The
main cplusplus.yo file contains an entry for (possibly) a new chapter.

The new sections will be added and once all have been added the new 8.0.0
version of the C++ will be released.
