This lacks test and documentation. Let me start by adding that, consistently.

netdb-h: Ensure AI_NUMERICHOST and AI_NUMERICSERV are defined.
* lib/netdb.in.h (AI_NUMERICHOST): New macro.
* tests/test-netdb-h.c: Verify that AI_NUMERICHOST and AI_NUMERICSERV
are defined.
* doc/posix-headers/netdb.texi: Mention the platform support for
AI_NUMERICHOST and AI_NUMERICSERV.
