In the preceding commits we have turned `struct odb_read_stream` into a
publicly visible structure. Furthermore, this structure now contains the
type and size of the object that we are about to stream. Consequently,
the out-pointers that we used before to propagate the type and size of
the streamed object are now somewhat redundant with the data contained
in the structure itself.
Drop these out-pointers and adapt callers accordingly.
