HEAD UP: correct type of addrinfo.ai_addrlen and netent.n_net

Hi,

I've committed to correct type of ai_addrlen member of struct addrinfo
and n_net member of struct netent.  Though it affects to 64 bit arch,
I believe it doesn't break ABI backward comatibility.
I'll remove padding for ABI backward comatibility after 2 weeks.  When
padding is removed, ABI backward comatibility will be lost on 64 bit
arch.

Sincerely,

attached mail follows:

    include              netdb.h 
    lib/libc/net         getaddrinfo.c getnetbydns.c getnetbyht.c 
                         getnetbynis.c getnetnamadr.c 
                         netdb_private.h 
  Log:
  - 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.
