repo-settings: consolidate some config settings
There are a few important config settings that are not loaded during git_default_config. These are instead loaded on-demand. Centralize these config options to a single scan, and store all of the values in a repo_settings struct. The values for each setting are initialized as negative to indicate "unset". This centralization will be particularly important in a later change to introduce "meta" config settings that change the defaults for these config settings.
