convert: add closesort algorithm to mercurial sources

If you actively work with branches, sometimes you need to close old branches
which last commited hundreds revisions ago. After close you will see long
lines in graph visually spoiling history. This sort only moves closed
revisions as close as possible to parents and does not increase storage size
as datesort do.
