gc: do not repack promisor packfiles

Teach gc to stop traversal at promisor objects, and to leave promisor
packfiles alone. This has the effect of only repacking non-promisor
packfiles, and preserves the distinction between promisor packfiles and
non-promisor packfiles.

@ -255,6 +255,17 @@ a missing object is encountered. This is the default action.
The form '--missing=allow-any' will allow object traversal to continue
if a missing object is encountered. Missing objects will silently be
omitted from the results.
+
The form '--missing=allow-promisor' is like 'allow-any', but will only
allow object traversal to continue for EXPECTED promisor missing objects.
Unexpected missing object will raise an error.
--exclude-promisor-objects::
Omit objects that are known to be in the promisor remote. (This
option has the purpose of operating only on locally created objects,
so that when we repack, we still maintain a distinction between
locally created objects [without .promisor] and objects from the
promisor remote [with .promisor].) This is used with partial clone.
