    fstest regression fixes - POSIX error codes.
    
    Deal with most of the issues found by FreeBSD's fstest regression test:
        * Limit path components to 255 characters.  Return ENAMETOOLONG if
          the limit is exceeded.
    
        * Return EEXIST, EINVAL, and ENOTEMPTY as appropriate when the user
          attempts to create, delete, or rename "." or "..", instead of EINVAL.
    
        * Return EISDIR if an attempt is made to open a directory for writing,
          instead of EINVAL.
    
        * Return EACCES if an attempt is made to open a file O_TRUNC without
          O_RDWR or O_WRONLY, instead of silently dropping the O_TRUNC.
    
        * Implement O_NOFOLLOW semantics generally instead of just with O_EXCL.
    
    Not dealt with:
        * DragonFly clears SGID AND SUID on uid or gid change, if not root.
          If root is doing the operation SGID/SUID is not cleared.
    
        * HAMMER cannot modify the ctime without rolling a new inode, which
          is very expensive, and does not do so when entries are added or
          removed from a directory.  mtime is modified.
