The "core.bigFileThreshold" setting is stored in a global variable and populated via `git_default_core_config()`. This may cause issues in the case where one is handling multiple different repositories in a single process with different values for that config key, as we may or may not see the correct value in that case. Furthermore, global state blocks our path towards libification. Refactor the code so that we instead store the value in `struct repo_settings`, where the value is computed as-needed and cached.
