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all values of "unsigned char", and this check is obsolete and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.

compiled lpd binaries. we should do it on next libc major version bump.
added a memo on lib/libc/shlib_version.

(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.

do not perform sleep() every time we get ECONNREFUSED.
try all the set of addresses before go to sleep() and retry.

not sure if we still need sleep() - retry logic. why is it so persistent
in connecting?

visit next addrinfo struct on socket failure.

this should fix the behavior of rcmd() on ipv4-only node, trying to
connect to dual stack node (AAAA and A record on DNS/hostname databaes)

add IPv6 support to rcmd() and friends.
rcmd() and iruserok(): unchanged
ruserok(): became address family independent
rcmd_af(), iruesrok_sa(): address family independent

Use a better type in previous.

Delint.

back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.

descriptors against -1 (as appropriate).

* 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

- fix gcc-2.8.1 warnings
- portability fix: Don't use bindresvport() if !BSD4_4 because we could
be on an operating system where it takes different arguments (hint, hint).

Portability. Use #ifdef BSD4_4 for sin_len

Use posix signal system calls.

const poisoning.
