*: s/void */til_setup_t */
This brings something resembling an actual type to the private objects returrned in *res_setup. Internally libtil/rototiller wants this to be a til_setup_t, and it's up to the private users of what's returned in *res_setup to embed this appropriately and either use container_of() or casting when simply embedded at the start to go between til_setup_t and their private containing struct. Everywhere *res_setup was previously allocated using calloc() is now using til_setup_new() with a free_func, which til_setup_new() will initialize appropriately. There's still some remaining work to do with the supplied free_func in some modules, where free() isn't quite appropriate. Setup freeing isn't actually being performed yet, but this sets the foundation for that to happen in a subsequent commit that cleans up the setup leaks. Many modules use a static default setup for when no setup has been provided. In those cases, the free_func would be NULL, which til_setup_new() refuses to do. When setup freeing actually starts happening, it'll simply skip freeing when til_setup_t.free_func is NULL.
