[PATCH 05/24] setbuf.3: SYNOPSIS: Use 'restrict' in prototypes

[Alejandro Colomar <alx.manpages@gmail.com>]

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

.../glibc$ grep_glibc_prototype setvbuf
libio/stdio.h:308:
extern int setvbuf (FILE *__restrict __stream, char *__restrict __buf,
		    int __modes, size_t __n) __THROW;
.../glibc$ grep_glibc_prototype setbuf
libio/stdio.h:304:
extern void setbuf (FILE *__restrict __stream, char *__restrict __buf) __THROW;
.../glibc$
