stdopen: modernize and simplify
* lib/stdopen.c: Update copyright date
Do not include sys/types.h; no longer needed these days.
(stdopen): Use C99-style decl in loop. Return int errno
value, rather than just a bool. Do not worry about fd mismatches,
since the caller cares only if 0, 1, 2 are occupied.
* lib/stdopen.h: No need to include <stdbool.h>.
* m4/stdopen.m4: Remove.
* modules/stdopen: New file.
