Fixes from Bill Fenner <fenner@research.att.com> for problems he found
in FreeBSD's port of this nsswitch code:

hosts:!!!!!!!!@@@@@$%^&

Fixes from Bill Fenner <fenner@research.att.com> for problems he found
in FreeBSD's port of this nsswitch code:

- Don't ignore unknown characters. The old lexer would treat
hosts:!!!!!!!!@@@@@$%^&*()()*$(files{}{}|||++!)(dns

hosts: files dns

- Recover from errors by looking for the end of a line. This means
that having a syntax error near the top of the file doesn't prevent
a service at the bottom of the file with no syntax error from being
looked up.

Thanks Bill!

add _nsyylineno declaration

don't use err(); instead pass an error condition back to a higher
layer to warn() about.

* 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
