Add __swhatbuf function from OpenBSD
To fix a long-standing setvbuf bug, import __swhatbuf function from
OpenBSD and only slightly rearrange for newlib.
* libc/stdio/local.h (__swhatbuf_r): Declare.
* libc/stdio/makebuf (__smakebuf_r): New function.
(__smakebuf_r): Drop file handling code and call __smakebuf_r.
