If we're going to introduce a new version of the CNFS format, maybe we
could deal with the other long-standing problem at the same time, namely
that the CNFS file format depends on the configuration parameters for the
INN build? If the CNFSv4 file format standardized uint32_t and uint64_t
values in network byte order, that would let us move CNFS buffers between
hosts and between largefile and non-largefile builds.
