[PATCH 15/22] mbtowc.3: SYNOPSIS: Use 'restrict' in prototypes

[Alejandro Colomar]

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

.../glibc$ grep_glibc_prototype mbtowc
stdlib/stdlib.h:925:
extern int mbtowc (wchar_t *__restrict __pwc,
		   const char *__restrict __s, size_t __n) __THROW;
.../glibc$
