Merge branch 'js/gc-repack-close-before-remove'

"git gc" and "git repack" did not close the open packfiles that
they found unneeded before removing them, which didn't work on a
platform incapable of removing an open file.  This has been
corrected.

* js/gc-repack-close-before-remove:
gc/repack: release packs when needed
