[PATCH 2/7] Add git_configset_add_standard

[Richard Maw <richard.maw@gmail.com>]

This exposes implementation details of repo_read_config
so a configset can be populated with a repository's standard config,
without needing to create a full repository.

This allows config lookup to use the same codepath
whether the repository is ready or not,
which allows it to be used during git init.
