[PATCH v2 4/9] object: add clear_commit_marks_all()

["René Scharfe" <l.s.r@web.de>]

Add a function for clearing the commit marks of all in-core commit
objects.  It's similar to clear_object_flags(), but more precise, since
it leaves the other object types alone.  It still has to iterate through
them, though.
