Add "local" versions of getnetgrent() et al. and now call those for the NIS
versions. Fix conditional compilation issues with YP and NSS_FILES.

nsdispatch()-ify getnetgrent() and friends.

Remove leftover debugging message. Problem pointed out by Kurt Schreiner

back out last change as it is actually a visible function.

define _ng_cycle to be static, so gcc won't whing about its implicit decl.

move include of StringList.h before netgroup.h

add an _ng_cycle function to print the list of netgroups that are are dups.

Remove trailing ; from uses of __weak_alias(). The macro inserts this if

* check the result of sl_init() and sl_add()

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

* 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

specifically include stdarg/varargs.h

pre nsswitch default was more like "files [notfound=return] nis"

Fix two problems with the recent nsswitch changes to netgroups:
- The historic mode for netgroups was "files nis". Change the default to
this for when /etc/nsswitch.conf does not exist.
- The nis lookup dispatch was mistakenly conditional on -DHESIOD, not -DYP.

* `passwd' defaults to `compat', and `passwd_compat' defaults to `nis'
* constify ns_dtab defs

convert to new nsdispatch(3)

trivial changes to reduce lint complaints

If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.

This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.

Fix memory corruption with double-freeing ng_copy. (From Jason Downs)

- Changed all internal libc references of {v,}err{x,} and {v,}warn{x,} to
__{v,}err{x,} and __{v,}warn{x,}
- moved err.c to __err.c and added err.c which contains weak references for
the above functions.
- Reordered the functions in __err.c to avoid redeclarations and changed
the varargs declarations to conform with the K&R style.

New netgroup implementation; replaces Rick's old one that did not
