fopencookie(3): Add a wrapper around funopen(3)
commit a765cedf26cef470ba7deee42c365f0221690a1a
Date:   Sat Feb 4 14:54:20 2023 +0100

changed /usr/include/stdio.h to add

+typedef ssize_t (cookie_read_function_t)(void *, char *, size_t);
+typedef ssize_t (cookie_write_function_t)(void *, const char *, size_t);
+typedef int (cookie_seek_function_t)(void *, off64_t *, int);
+typedef int (cookie_close_function_t)(void *);
+typedef struct {
+       cookie_read_function_t  *read;
+       cookie_write_function_t *write;
+       cookie_seek_function_t  *seek;
+       cookie_close_function_t *close;
+} cookie_io_functions_t;
+FILE   *fopencookie(void *, const char *, cookie_io_functions_t);

These new functions are guarded by nothing, yet ssize_t has a definition
in the same header file guarded by something.  Trying to build say png,
the compile is confused about ssize_t, among other things.  For now, moving

#endif /* __BSD_VISIBLE */

to cover the new functions and structs allows png to build, but I
cannot guarantee other packages will regard this as sufficient.
