fsck: optionally show more helpful info for broken links

When reporting broken links between commits/trees/blobs, it would be
quite helpful at times if the user would be told how the object is
supposed to be reachable.

With the new --name-objects option, git-fsck will try to do exactly
that: name the objects in a way that shows how they are reachable.

For example, when some reflog got corrupted and a blob is missing that
should not be, the user might want to remove the corresponding reflog
entry. This option helps them find that entry: `git fsck` will now
report something like this:

	broken link from    tree b5eb6ff...  (refs/stash@{<date>}~37:)
	              to    blob ec5cf80...
