Adds ability to use device-global names in command args, in particular cmd->start_arg (for NI_CtrArmStartTrigger), and cmd->scan_begin_arg or cmd->convert_arg (either is used to specify NI_CtrGate, with preference given to cmd->scan_begin_arg, if it is set). The actual arguments of cmd->start_arg are not fully checked against known register values for the particular devices because these are not documented or currently known. This follows the precedence of prior versions of the tio driver. Should these become known, they should be annotated in the route_values tables and the set of lines in ni_tio_cmdtest should be uncommented to allow the tests to be made. This patch also adds interface functions that allow routes for particular counter route destinations to be made/queried/unmade. This allows overseer modules to implement test_route, connect_route, and disconnect_route. As a part of these changes, various functions were cleaned up and clarified. These new interface functions allow direct writing/reading of register values. This is an example of exactly what the new device-global access was intended to solve: the old interface was not consistent with other portions of the ni_* drivers--it did not allow full register values to be given for various MUXes. Instead, the old interface _did_ abstract away some of the actual hardware from the underlying devices, but it was not consistent with any other NI hardware. Allowing the device-global identifiers to be used, the new patch provides for consistency across all ni_* drivers. One final note: these changes provide for backwards compatibility by allowing the older values to still be used in through the pre-existing kernel interfaces--though not in the new device-global test/dis/connect/route interfaces.
