    MFC: fstest regression fixes - POSIX error codes.
    
    Partial MFC of d7c75c7a20590cab729c3d653aaa91a4960d6165:
    
    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 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 MFC'd:
        * Return EISDIR if an attempt is made to open a directory for writing,
          instead of EINVAL.
    
    This is required so that /usr/bin/tar can extract to an existing
    directory:
    
    	tar cf - . | (cd otherdir && tar xof -)
    
    failed before (breaking nrelease).
