Routine Description:

  pValidateBlock makes sure Block is non-NULL.  If it is NULL, then the user
  is given a popup, unless the request size is bogus.

  There are two cases for the popup.

   - If g_OutOfMemoryParentWnd was set with SetOutOfMemoryParent,
     then the user is asked to close other programs, and is given a retry
     option.

   - If there is no out of memory parent, then the user is told they
     need to get more memory.

  In either case, Setup is terminated.  In GUI mode, Setup will be
  stuck and the machine will be unbootable.

Arguments:

  Block - Specifies the block to validate.
  Size - Specifies the request size

Return Value:

  none
