mbstowcs.3: SYNOPSIS: Use 'restrict' in prototypes 

Both POSIX and glibc use 'restrict' in mbstowcs().
Let's use it here too.

.../glibc$ grep_glibc_prototype mbstowcs
stdlib/stdlib.h:933:
extern size_t mbstowcs (wchar_t *__restrict  __pwcs,
			const char *__restrict __s, size_t __n) __THROW
    __attr_access ((__read_only__, 2));
.../glibc$
