Currently the dive computer backends are responsible for opening (and closing) the underlying I/O stream internally. The consequence is that each backend is hardwired to a specific transport type (e.g. serial, irda or usbhid). In order to remove this dependency and support more than one transport type in the same backend, the opening (and closing) of the I/O stream is moved to the application. The dc_device_open() function is modified to accept a pointer to the I/O stream, instead of a string with the device node (which only makes sense for serial communication). The dive computer backends only depend on the common I/O interface.
