We were reading in a segment's stream ID and position, and assuming that
was enough for the downloader. But of course, the downloader needs
AliasPieces filled in. So now we request each segment record from the
metabase and fill in the VerifySegment records entirely.

This will allow us to retry some specific segments from
segments-retry.csv with particularly high counts of "retry" pieces.

It was ok as it was, but since we want to keep a close eye on progress
while the tool is running, it will help to have results written to the
output file immediately instead of after the buffer is full or the
program exits.

This adds the capability to the segment-verify tool of checking all
pieces of every indicated segment.
Pieces which could not be accessed (i.e. we couldn't get a single
byte from them) are recorded in a csv file.
I haven't been able to test this in any very meaningful way, yet, but I
am comforted by the fact that the worst things it could possibly do are
(a) download pieces too many times, and (b) miss downloading some
pieces.
