The Big Crypto Merge of 2004.
* lib/Makefile.am: updated for jgss resources.
* lib/gen-classlist.sh.in: updated for classes in org/.
* javax/security/auth/x500/X500Principal.java: replaced with GNU
Crypto's version.
* resource/org/Makefile.am,
* resource/org/ietf/Makefile.am,
* resource/org/ietf/jgss/Makefile.am:
new files.
