The current commit replaces the vuart library by a devmap library.
        The goal is to provide a common way for test programs to map a PCI or
        VME resource. Of course the VME inplementation is highly dependant of
        the PCI/VME bridge.
        This new library is not specific to wrpc and should be reconsidered in
        respect with UAL project. For the time being it is located here,
        because it serves the purpose of writing test program for wrpc.
