setup: constify settings passed to setup_func
setup_func isn't formally defined for libtil, but setup_interactively() defacto establishes it and til_module_t.setup() reflects the same signature and calling convention except with til_settings_t constified. This change makes them all consistent in this regard, but there should probably be a formal typedef added for the function. The reason for constifying this is I don't want setup functions directly manipulating the settings instance. In the case of rototiller::setup_interactively() we ensure the stdio-based interactive setup is always the side doing the manipulation of the settings. For a libtil-user like glimmer, it's slightly different beast with GTK+ in the loop, but by preventing the setup_funcs from messing directly with the settings (instead having to describe what they want done iteratively), the front-end always gets its opportunity to maintain its state while doing the described things. Of course, this is mostly a lie, and within libtil the constified til_settings_t gets cast away to modify it in places. But keeping that limited to within libtil is tolerable IMO. We just don't want to see such casts in module code.
