Win32 IXXAT driver:
CHANGED: - Removed deprecated call to VCI_GetBrdTypeByName().
- The board type given to VCI2_PrepareBoard() is now always 0, because this parameter is not used.
- Removed the board_name parameter from IXXAT::open(). The board that should be opened is identified by the parameter board_number.
The correct parameter board_number can be determined using XAT_EnumHwEntry() and XAT_GetConfig().
- Changed the constructor IXXAT::IXXAT(). board->busname now only contains the board_number, see XAT_EnumHwEntry() and XAT_GetConfig().
