  SVN rev 202805 on 2010-01-22 11:42:44Z by trasz
  
  MFC c195785:
  
  Fix permission handling for extended attributes in ZFS.  Without
  this change, ZFS uses SunOS Alternate Data Streams semantics - each
  EA has its own permissions, which are set at EA creation time
  and - unlike SunOS - invisible to the user and impossible to change.
  From the user point of view, it's just broken: sometimes access
  is granted when it shouldn't be, sometimes it's denied when
  it shouldn't be.
  
  This patch makes it behave just like UFS, i.e. depend on current
  file permissions.  Also, it fixes returned error codes (ENOATTR
  instead of ENOENT) and makes listextattr(2) return 0 instead
  of EPERM where there is no EA directory (i.e. the file never had
  any EA).
