Cause getaddrinfo() without socktype specification to work correctly for
...
numeric addresses. The documentation appears to say this works, and some
other systems support it -- more importantly, why should it _not_ work? If
it does not, getaddrinfo() cannot be used as a general-purpose textual to
binary address conversion utility function; yet it is the only such function
we have in the system, since inet_pton() requires a priori knowledge of the
address family.
This change also causes getaddrinfo() with NULL hint (expressly documented
as working) to work properly for numeric addresses.

From: "Jason L. Wright" <jason@thought.net>
...
The man page for getaddrinfo() and RFC2553 says it should return EAI_NONAME
for the case where hostname != NULL, hostname is not a numeric string and
ai_flags has the AI_NUMERICHOST bit set. Instead, it returns EAI_NODATA
for this case. The diff below makes it return EAI_NONAME for this case.
This is why ntpq and ntpdc from ntp-4.1.74 can't resolve hostnames,
but work fine with numeric strings like ::1 or 127.0.0.1.

struct addrinfo.ai_addrlen used to be a size_t, per RFC 2553.
...
In XNS5.2, and subsequently in POSIX-2001 and draft-ietf-ipngwg-rfc2553bis-02
it was changed to a socklen_t.
To accomodate for this while preserving binary compatibility with the
old interface, prepend or append 32 bits of padding, depending on
the (LP64 data model) architecture's endianness.
This should be deleted the next time the libc major number is
incremented.
