Merge branch 'js/fsck-opt'
Allow ignoring fsck errors on specific set of known-to-be-bad objects, and also tweaking warning level of various kinds of non critical breakages reported. * js/fsck-opt: fsck: support ignoring objects in `git fsck` via fsck.skiplist fsck: git receive-pack: support excluding objects from fsck'ing fsck: introduce `git fsck --connectivity-only` fsck: support demoting errors to warnings fsck: document the new receive.fsck.<msg-id> options fsck: allow upgrading fsck warnings to errors fsck: optionally ignore specific fsck issues completely fsck: disallow demoting grave fsck errors to warnings fsck: add a simple test for receive.fsck.<msg-id> fsck: make fsck_tag() warn-friendly fsck: handle multiple authors in commits specially fsck: make fsck_commit() warn-friendly fsck: make fsck_ident() warn-friendly fsck: report the ID of the error/warning fsck (receive-pack): allow demoting errors to warnings fsck: offer a function to demote fsck errors to warnings fsck: provide a function to parse fsck message IDs fsck: introduce identifiers for fsck messages fsck: introduce fsck options
