%ls and %lc in scanf.c

We've added widechar support to vfscanf - %S, %ls, %C, %lc modifiers. 
The code was given from FreeBSD's vfprintf.c - since
Newlib's license is BSD, I think this is legal.

The patch was tested a little bit - with default locale and UTF8-based 
locale. If mbsrtowcs and mbrtowc work well, this should work too.

One issue that I've met - '#ifndef CYGNUS_NEC' macro that surrounds 
__srefill function. I've added it to %C and %S-related code 
(analogiously as it is in %c and %s-related code) but not sure if this 
is correct.

Please, see, and enjoy :-))
