Subject: r4173: - new t2open code, that can cope with "create with EAs". Many
 thanks   to kukks on #samba-technical for the sniffs that allowed me to work 
  this out

- much simpler ntvfs open generic mapping code

- added t2open create with EA torture test to RAW-OPEN test
(This used to be commit a56d95ad89b4f32a05974c4fe9a816d67aa369e3)
