[hacknews] dump

Dump(1) has been improved in some small ways (use of getopt(3), internal
cleanup), and has been changed to check for write errors (!) on the tape.

Dump(1) has been further modified to not insist on having its tape
mounted until after pass II; this will let us overlap rewind time with
the "think time" in pass I and II.  As a side effect of this, for
complicated and confused reasons, dump(1) actually temporarily is
*not* using getopt(3), contrary to the previous posting.  This will
be fixed, probably tomorrow.

We're now running (actually, this happened very late yesterday afternoon)
a version of dump(1) that forks off an auxiliary process to do its tape
writes.  This was done in hopes of greater speed, through concurrent disk
and tape operations.  It may have speeded things up some; the effect was
not spectacular.  More to come.
