  Log:
  Fix an overflow in the GPT code, I wasn't allocating enough slice structures.
  Fix the openmask array declaration, it was declaring too-large an array.
  
  Disallow GPT partitions with invalid spans.
  
  When calculating a virgin disklabel take into account the possibility of
  absurdly small GPT or MBR slices that would cause the calculation of
  disklabel->d_ncylinders to result in 0.  Reduce the number of heads and
  the number of sectors per track until a reasonable cylinder count is
  achieved.
