commit 84ba60e6ebc9a2ea3898278b2a6a9669cd5b58b5

gai_strerror() - Update string error messages according to RFC 3493.
Error messages in gai_strerror(3) vary largely among OSs.
For new software we largely replaced the obsoleted EAI_NONAME and
with EAI_NODATA but we never updated the corresponding message to better
match the intended use. We also have references to ai_flags and ai_family
which are not very descriptive for non-developer end users.
Bring new new error messages based on informational RFC 3493, which has
obsoleted RFC 2553, and make them consistent among the header adn
manpage.
