And IIRC we were stuck on the convention to tell which ones are
archives and which ones are actives (i.e. fair game for
repacking).  We were trying to figure out how to mark active
ones (whose name changes every time you repack).

I realized that there is a very simple and obvious solution for
it.  Introduce $GIT_OBJECT_DIRECTORY/info/archived-packs, a flat
text file that lists the names of the archive packs.  Any pack
not listed there are active one and are subject to repacking.
