Commits


replace inline code with call to open_commit() helper


rename got_parent_id to got_object_qid; better generic name


do not store commits in the commit graph; saves memory


remove unused function


parse commit timestamps when opening commits


move parse_commit_time() to object.c and make public API


some commits were missing from the commit graph


commit graph: don't omit commits with equal timestamps


basic commit graph; make 'got log' use it; WIP with known bugs
