Previously, the address of the CAN device (`CANbaseAddress`)
was specified as a signed or unsigned integer of variable size.
This made the ABI specific for each driver and is not generic
enough for some use cases.
Replaced all usages by using a void pointer instead.
Renamed `CANbaseAddress` to `CANdevicePtr`.
Refactored the code where it needed to be (some comparisons to -1).
Use a pointer to a user-defined variable/structure instead of
a 32-bit integer for CANbaseAddress. Renamed CANbaseAddress
to CANbaseStruct to reflect that change in behavior.
This is more modular and avoids casts.
- needs #define CO_NO_LSS_CLIENT 1 in CO_OD.h. This will need a change in the OD editor.
- still no fastscan support
- bitrate settin API untested
- some changes on LSS slave where necessary
