    catopen(3): align returned errors with POSIX.1-2024
    
    Return ENOENT instead of EFTYPE for invalid/empty names, non-existent
    catalogue files, and bad catalogue headers.  Require the complete header
    and reject sizes that exceed mmap() limit.
    
    Also save the errno in handling the open() failure.
