Move the global 'has_symlinks' configuration into the repository-specific 'repo_config_values' struct. Introduce 'repo_has_symlinks()' getter for readability. Callers access this configuration by passing in 'repo' when possible, and explicitly fall back to 'the_repository' the rest of the time. Introduce 'platform_has_symlinks()' macro to allow platform specific-customization, primarily to help MinGW. Platforms can override this in their respective headers.
