Hello, I got several reports for name resolution error after
	ftp/telnet/whatever update for dual stack support in NetBSD-current.
	The trouble arise when you have "hosts: files dns" line in
	/etc/nsswitch.conf.

	I believe the following fixes your problem.  If you still see
	the problem, please contact me.

	Sorry for make you waited and thanks very much for your reports!

	(Could anybody who is using NIS check the behavior or resolver?)

Log Message:
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)
