Olamide Caleb Bello f9b3c1f731 environment: stop storing core.attributesFile globally
The `core.attributeFile` config value is parsed in
git_default_core_config(), loaded eagerly and stored in the global
variable `git_attributes_file`. Storing this value in a global
variable can lead to it being overwritten by another repository when
more than one Git repository run in the same Git process.

Create a new struct `repo_config_values` to hold this value and
other repository dependent values parsed by `git_default_config()`.
This will ensure the current behaviour remains the same while also
enabling the libification of Git.

An accessor function 'repo_config_values()' s created to ensure
that we do not access an uninitialized repository, or an instance
of a different repository than the current one.
