Stop including <sys/param.h> from <netdb.h>. Portable software must either
include <sys/param.h> (to operate in legacy mode) or if it wishes to operate
in the POSIX world use <limits.h>

Implement AI_ADDRCONFIG

This is a getaddrinfo() flag that is defined thusly in RFC 3493:

If the AI_ADDRCONFIG flag is specified, IPv4 addresses shall be
returned only if an IPv4 address is configured on the local system,
and IPv6 addresses shall be returned only if an IPv6 address is
configured on the local system. The loopback address is not
considered for this case as valid as a configured address.

For example, when using the DNS, a query for AAAA records should
occur only if the node has at least one IPv6 address configured
(other than IPv6 loopback) and a query for A records should occur
only if the node has at least one IPv4 address configured (other
than the IPv4 loopback).

The flag is set by default when hints is NULL.

Add AI_FQDN flag to getaddrinfo(3). Prompted by discussions with djm@
about cert checking in OpenSSH. Man page wording tweaks thanks to
jmc@.

Committing now to reuse guenther@'s libc minor bump instead of
cranking it again, as suggested by deraadt@.

- define EAI_OVERFLOW, as per IEEE Std 1003.1-2001(Interpretation #13)

First step in include files overhaul. Use __FOO_VISIBLE (as defined
in sys/cdefs.h) instead of _FOO_SOURCE. Also fix several namespace
pollution issues, including the byte order defines. OK deraadt@

Make gethostbyaddr() prototype match POSIX. This means len is now
unsigned but there is no ABI change. OK deraadt@

remove NI_WITHSCOPEID

Change return value of reentrant getproto* and getserv* to match the
IBM/Digital API.

Reentrant versions of getprotoent(3) and getservent(3). Adapted from

Manual cleanup of remaining userland __P use (excluding packages maintained outside the tree)

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

change ai_addrlen to socklen_t. now it conforms to
draft-ietf-ipngwg-rfc2553bis-03.txt. backward compatibility concern:
- should be safe to change signed to unsigned, as we never return
negative value.
- sizeof(int) is 4 for all archs, so there's no size change with socklen_t
(= u_int32_t)

commented by deraadt.

Remove parameter names in prototypes (always a bad idea)

correct type of 2nd argument to meet RFC2553. (this should raise no ABI
problem due to type promotion). PR 1228.

revise extended scoped address format support. delimiter and the order
is changed, based on discussion in ipngwg scoped address cabal.
past code: fe80::1@de0
now: de0%fe80::1
this will be in sync with next extended address format proposal
(which should be final - I don't want to make this kind of change again).

replace NRL get{addr,name}info with KAME get{addr,name}info.

removed functionality:
new code will not return AF_LOCAL addrinfo struct.
added funtionality:
SOCK_RAW is permitted as ai_socktype (no servname allowed).

proto net_addrcmp()

Added some protocol independent interfaces (supposedly IPv6 support APIs, but
ones that are useful for all protocols, not just IPv6).
