- Remove padding for ABI compatibility of n_net member from struct

  netent.
- Change 1st argument of getnetbyaddr() to an uint32_t on 64 bit
  arch as well to confirm to POSIX-2001.

These changes break ABI compatibility on 64 bit arch.
There is similar padding issue for ai_addrlen of struct addrinfo.
However, it is leaved as is for now.

Discussed on:	arch@, standards@ and current@
X-MFC after:	never

- The ai_addrlen of a struct addrinfo used to be a size_t, per

2005-05-15T20:15:15+00:00

  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.

NETDB_INTERNAL is not fit, here. return NO_RECOVERY for h_errno.

Fix the style of the SCM ID's.

I believe have made all of libc .c's as consistent as possible.

Remove 'register' keyword.

Removed duplicate VCS ID tags, as per style(9).

Add nsswitch support. By creating an /etc/nsswitch.conf file, you can

2000-09-06T18:16:48+00:00

configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
  functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
    . getgrent, getgrnam, getgrgid
    . getpwent, getpwnam, getpwuid
    . getusershell
    . getaddrinfo
    . gethostbyname, gethostbyname2, gethostbyaddr
    . getnetbyname, getnetbyaddr
    . getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc.  rc.network has been modified
  to warn that host.conf is no longer used at boot time.  In addition, if
  there is a host.conf but no nsswitch.conf, the latter is created at boot
  time from the former.
