*: 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.
