zstream currently contains three identical copies of dump_record(), which appear to all be drawn from libzfs_sendrecv.c. The original is marked internal. This PR adds zstream_util.[hc] and puts the shared code there along with a couple of other items in common. No functional changes. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Garth Snyder <garth@garthsnyder.com> Closes #18284
