b48252f365 * use _DIAGASSERT() to check pointer arguments against NULL and file 
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
  and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

		_DIAGASSERT(path != NULL)
	#ifdef _DIAGNOSTIC
		if (path == NULL) {
			errno = EFAULT;
			return (-1);
		}
	#endif

bc3bad7a1c - provide reverse query for mapped address (::ffff:10.1.1.1). 
- NI_NUMERICHOST and NI_HOSTREQD conflict with each other,
  so bark if there are both.

f958dccbd1 - do not make query for AFs that are not supported by kernel. 
i.e. do not make query for IPv6 addresses, when running on non-IPv6 kernel,
  or, do not query for IPv4 address on IPv6-only kernel :-)

  This kind of behavior is not very well documented in RFC2553.  This
  may violate the spec.

- on EAI_AGAIN, only retry 3 times (3 is a magic number).  Previous code
  made retries forever.  This solves situation where name server is wrongly
  configured and nameserver:53 returns icmp port unreach.

The only proper fix for all getaddrinfo() related twists would be to
implement getipnodebyname() and get rid of wacky get_addr().
We need to contribute bind8 development for this.

2842a2f6bb fix name resolution problem when you have "hosts: files dns" on 
/etc/nsswitch.conf.

This was because of two reasons:
- /etc/hosts lookup code damaged some of internal
  state used by gethostbyname2().
- getaddrinfo() was not persistent enough against errors.

Sorry for the delay, and hope this fix all the following PRs
(I checked in my environment immitating those PRs and it worked for me)

db0f8786bd if the list of name server on /etc/resolv.conf is in a 
non-supported AF, try the next nameserver instead of abort.

This helps situations like:
- you write IPv6 nameserver into /etc/resolv.conf and
- run non-IPv6 kernel

abd1f8ab5b capitalize the first word of most error strings except those words that are 
argument names to the function. e.g, if `const char *servname' is an argument
name, keep using "servname invalid [...]" instead of "Servname invalid [...]"

37e8159125 add IPv6 support functions. 
get{addr,name} info are implemented to have as little impact to existing
resolver code as possible, so they are NOT the optimal implementation.
They are at this moment not very thread safe (as they call
gethostby{name,addr}).

(shlib minor version)++, as new interfaces are added.

TODO: getipnodeby{name,addr} - which needs total reimplementation of
gethostby{name,addr}.
upgrade rcmd.c for multiple af support (needed for IPv6-ready rsh/rlogin)
