I'm going to use the file info block real soon now and noticed that
doing it with the schema way brings only hassle for no good.  The info
is per file, hence probably the same scheme won't be reused by anything
else.  Hence going back to nearly the old way.  I do have use for a
counted type, in order to skip safely over unknown entries.  Old SOLV
files can be read when they don't have any file info.  None should
have.
