 DosGetHugeShift()
------------------------------------------------------------------------------
 Purpose:
 Get the left shift count to apply to 1 to get the huge selector increment
 value.

 Syntax:
 USHORT BLXAPI DosGetHugeShift(PUSHORT shiftcount);

 Parameters:
 shiftcount  Pointer to an integer to receive the huge shift value.

 Returns:
 Left-shift count integer.

 Description:
 The huge increment value is obtained by applying the left-shift count
 returned by this function to 1. For example, a left-shift count of 3 gives
 a huge increment of 8 (1 << 3 == 8). This increment is added to the base
 selector returned by DosAllocHuge() to give the next consecutive selector
 for a huge memory block.

 Example:
 #include <stdlib.h>                                                         
 #include <stdio.h>                                                          
 #include <string.h>                                                         
 #include <blx286.h>
