7daefc5a5a Passing "char" values to ctype(3) functions is problematic. 
If an argument of a ctype function is outside "unsigned char"
and if it is not EOF, the behavior is undefined.

The isascii(3) is the sole exception of above and it was used to
be used to check a value was valid for other ctype functions in
ancient systems.  On modern systems, the ctype functions take
all values of "unsigned char", and this check is obsolete and
even wrong for non-ASCII systems.  However, we leave the isascii()
untouched for now, so as not to change the current behavior.

f447d9b890 to get (f)lex output to go to stdout, use -t (a flag supported by

"/dev/stdout" function in the expected manner.

2dc247fc34 make CMSG_ALIGN always synchronize with kernel's idea of ALIGNBYTES. 
ancillary data alignment will be ALIGNBYTES, not sizeof(long) - 1, from now.

CMSG_xx will NOT resolve into constant.  if you use CMSG_xx to allocate
arrays, you'll lose.

bump shlib minor for libc.

NOTE: if you are on top of arch with ALIGNBYTES != sizeof(long) - 1,
you need to recompile IPv6-related binaries.  there is no way to guarantee
backward compat in this aspect.  sorry for this.  this should be the last
backward compat breakage for IPv6-related ancillary data manipulation.

7b48263c7b (rcmd.c) to make Zoularis happier, pass sa_len separately from sockaddrs. 
this changes function prototype for __ivalid*.
This commit breaks binary compatibility for __ivalid*.  I believe this can be
forgiven due to the following:
- this is not really exported function.  no function prototype is in headers.
  function name starts with underbars.  No third-party applications are
  expected to use it.
- the function was introduced very recently, when rcmd.c was made IPv6-ready.
- the only customer in NetBSD tree is lpd.

(lpd.c) sync with rcmd.c change.

the behavior was introduced in 1.8 -> 1.9, by itojun, and it was

even if we may be able to connect to the the returned addresses,
filtering them out is not a correct thing to do.  for example, even if
you have partial unreachablility in IPv4, gethostbyname(3) will return
IPv4 addresses in the unreachable network nonetheless.

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.
