Remove __need_list_t and __need_res_state.
These __need macros are only used internally, by nptl/descr.h. However, including all of resolv.h from descr.h causes build failures due to resolv.h's dozens of pseudo-struct-field macros, some of which collide with struct fields in NPTL internal data structures. Similarly, including all of list.h from descr.h produces an include cycle, atomic.h -> atomic-machine.h -> tls.h -> descr.h -> list.h -> atomic.h, and then list.h tries to use atomic.h macros that haven't been defined yet. So we do need mini-headers for these. In the list.h case I called it include/list_t.h since it isn't going to be installed. * resolv/resolv.h: Remove __need_res_state logic. Move definition of res_state and related constants to ... * resolv/bits/types/res_state.h: ...this new file. * resolv/Makefile: Install bits/types/res_state.h. * include/bits/types/res_state.h: New wrapper. * include/list.h: Remove __need_list_t logic. Move definition of list_t to ... * include/list_t.h: ...this new file. * nptl/descr.h: Include list_t.h and bits/types/res_state.h instead of list.h and resolv.h.
