[svn] * src/database.c,src/protocol.c,src/util.c,src/util.h: The latest IETF
article format draft draft-ietf-usefor-article-06.txt recommends that
Xref: references contain the FQDN of the server. We were using the
host name without the domain. So split the routine used for obtaining
the FQDN from protocol.c into util.c, and use it when adding Xrefs.
