Move the fsck_config() function from builtin/fsck.c to fsck.[ch]. This allows for re-using it in other tools that expose fsck logic and want to support its configuration variables. A logical continuation of this change would be to use a common function for all of {fetch,receive}.fsck.* and fsck.*. See5d477a334a
(fsck (receive-pack): allow demoting errors to warnings, 2015-06-22) and my own1362df0d41
(fetch: implement fetch.fsck.*, 2018-07-27) for the relevant code. However, those routines want to not parse the fsck.skipList into OIDs, but rather pass them along with the --strict option to another process. It would be possible to refactor that whole thing so we support e.g. a "fetch." prefix, then just keep track of the skiplist as a filename instead of parsing it, and learn to spew that all out from our internal structures into something we can append to the --strict option. But instead I'm planning to re-use this in "mktag", which'll just re-use these "fsck.*" variables as-is.
