sequence near EOF), so we can't just check for
(wc == WEOF && !__sfeof(fp)) and must relay on __sferror(fp) with
__SERR clearing/restoring.

i.e. partial line, but set __SERR and errno in the same time, which
is inconsistent.
Now both OpenBSD and NetBSD return failure, i.e. no line and set error
indicators for such case, so make our fgetln() and fgetwln()
(as its wide version) compatible with the rest of *BSD.

return partial line on any errors. See the comment in fgetln.c.
Add corresponding comment to fgetwln() too.
2) Rewrite r304607 case 1).
3) Remove "Fast path" from __fgetwc_mbs() since it can't detect encoding
errors and ignores them all.

1) Don't forget to set __SERR on __slbexpand() error.
2) Check for __fgetwc() errors using errno. Don't check for __SERR
as PR suggested, it user-visible flag which can stick from previous
functions and stdio code don't check it for this purpose.

load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter. Also
adds support for per-thread locales. This work was funded by the FreeBSD
Foundation.
Please test any code you have that uses the C standard locale functions!
