XboX HD Maker V1.9

Changes :

- Updated the "Sha1 Middle Message" hack of xbox_tool
  (xinfo) and hdtool (locking/unlocking) to support the 
  v1.6 xbox eeprom encryption. No eeprom keys included
  - it's still legal :)
  This means that xboxhdm can be used to build HDD's for v1.6
  xbox's now.

- Introduced hdparm in xboxhd to be able to force the kernel
  to reinitialize the partition tables after the fatx tables
  are written (option 1) or wiped (option 5).
  This means no more rebooting.
