Merge branch 'nd/commit-util-to-slab'
The in-core "commit" object had an all-purpose "void *util" field, which was tricky to use especially in library-ish part of the code. All of the existing uses of the field has been migrated to a more dedicated "commit-slab" mechanism and the field is eliminated. * nd/commit-util-to-slab: commit.h: delete 'util' field in struct commit merge: use commit-slab in merge remote desc instead of commit->util log: use commit-slab in prepare_bases() instead of commit->util show-branch: note about its object flags usage show-branch: use commit-slab for commit-name instead of commit->util name-rev: use commit-slab for rev-name instead of commit->util bisect.c: use commit-slab for commit weight instead of commit->util revision.c: use commit-slab for show_source sequencer.c: use commit-slab to associate todo items to commits sequencer.c: use commit-slab to mark seen commits shallow.c: use commit-slab for commit depth instead of commit->util describe: use commit-slab for commit names instead of commit->util blame: use commit-slab for blame suspects instead of commit->util commit-slab: support shared commit-slab commit-slab.h: code split
