issue #6733 invalid cite anchor id when using crossref

The crossreference possibility was not properly taken into account in bibtex conversion for other formats than LaTeX.
- doxygen.bst: use correct labels (i.e. add 'CITEREF_' in case of crossreferences to the giver name)
- cite.cpp: add the crossreferences to the citation dictionary (to overcome warning message).
- extending test 012
