The path subsytem provides a bunch of legacy functions that compute paths relative to the "gitdir" and "commondir" directories of the global `the_repository` variable. Use of those functions is discouraged, and it is easy to miss the implicit dependency on `the_repository` that calls to those functions may cause. With `USE_THE_REPOSITORY_VARIABLE`, we have recently introduced a tool that allows us to get rid of such functions over time. With this define, we can hide away functions that have such implicit dependency such that other subsystems that want to be free of `the_repository` will not use them by accident. Move all path-related functions that use `the_repository` into a block that gets only conditionally compiled depending on whether or not the macro has been defined. This also removes all dependencies on that variable in "path.c", allowing us to remove the definition of said preprocessor macro.
