	For use when setup functions allocate their private setup to return in res_setup. They specify the size of their private setup, and supply the free function to use. This may be libc's free() when it's a simple setup struct, or a bespoke free function when deep/complex freeing is required for cleanup. It's expected that callers will be embedding til_setup_t at the start of their private setup struct, and returning a pointer to this in res_setup which would be the same value as a pointer to to their private setup struct.
2022-04-24	til_setup: introduce til_setup_t	Vito Caputo
	Preparatory commit for providing a res_setup type to replace void. The impetus for this isn't just pursuit of less void, but primarily implementing setup freeing by embedding this struct into the private setup types. An alternative method of adding setup freeing would have been to introduce something like til_module_t.free_setup(). But that would require having the til_module_t on hand, and the whole setup machinery is more generalized than til_module_t anyways. This way anything can simply embed the struct in their private setup instance and return the pointer to that in res_setup. They should always be able to find their containing struct's offset from the til_setup_t they returned. Either by using container_of(), or simply placing it at the start of the private setup struct.
