The implementation of curl_dogetnameinfo was removed in 2018 (commit 0aeca41), but the declaration was still in the header. This would normally be irrelevant since it is guarded by the macro HAVE_GETNAMEINFO which is never defined, but if curl is included by a parent cmake project that also includes c-ares, HAVE_GETNAMEINFO will be defined and compilation will fail.
The second commit removes the getnameinfo-related macros from the config headers, since they are unused. It does not remove them from packages/vms/config_h.com because I'm not familiar with VMS and can't test any changes.
