7a6cd620d0 - The ai_addrlen of a struct addrinfo used to be a size_t, per 
RFC 2553.  In XNS5.2, and subsequently in POSIX-2001 and RFC
  3493, it was changed to a socklen_t.  And, the n_net of a
  struct netent used to be an unsigned long integer.  In XNS5,
  and subsequently in POSIX-2001, it was changed to an uint32_t.
  To accomodate for this while preserving ABI compatibility with
  the old interface, we need to prepend or append 32 bits of
  padding, depending on the (LP64) architecture's endianness.
- Correct 1st argument of getnetbyaddr() to uint32_t on 32
  bit arch.  Stay as is on 64 bit arch for ABI backward
  compatibility for now.

Fix the matchlen() function so that it handles the IPv4 (AF_INET)
case correctly.  Until now it has been treating IPv4 addresses
as if they were IPv6 which could lead to corruption errors.

5acac5def1 - do validation check and IPv4-mapped IPv6 address handling before 
any query.
- don't query against IPv6 link-local address.
- use IN6_IS_ADDR_V4{MAPPED,COMPAT} macros.
- use memcpy() instead of bcopy().

90a7ec34ec Remove a check about whether sa->sa_len is equal to salen from 
getnameinfo(3).  POSIX standard does not require a sa_len field
in sockaddr struct, hence such requirement will cause problem
for portability.
