Today the maximum record lenth in a migration stream is 8MB. This
limits the size of a PV domain to a little bit less than 1TB in the
migration case, as the P2M frame list will exceed 8MB in this case.
Raising the record size limit by a factor of 16 allows for domain
sizes of nearly 16TB to be migrated. This ought to be enough.

Provide the C structures matching the binary (wire) format of the new
stream format. All header/record fields are naturally aligned and
explicit padding fields are used to ensure the correct layout (i.e.,
there is no need for any non-standard structure packing pragma or
attribute).
Provide some helper functions for converting types to string for
diagnostic purposes.
