sparse-checkout: split out code for tweaking settings config

Browse source 
`init` has some code for handling updates to either cone mode or
the sparse-index setting.  We would like to be able to reuse this
elsewhere, namely in `set` and `reapply`.  Split this function out,
and make it slightly more general so it can handle being called from
the new callers.
