[PATCH v5 0/4] Per-worktree config file support

Let's get this rolling again. To refresh your memory because it's half a year since v4 [1], this is about letting each worktree in multi worktree setup has their own config settings. The most prominent ones are core.worktree, used by submodules, and core.sparseCheckout.

This time I'm not touching submodules at all. I'm leaving it in the good hands of "submodule people". All I'm providing is mechanism. How you use it is up to you. So the series benefits sparse checkout users only.

Not much has changed from v4, except that the migration to new config layout is done automatically _update_ a config variable with "git config --worktree".

I think this one is more or less ready. I have an RFC follow-up patch about core.bare, but that could be handled separately.
