This converts our old custom IO model to the new model that libdivecomputer introduced. This is partly based on Jef's rough patch to make things build, with further work by me. The FTDI code is temporarily disabled here, because it will need to be integrated with the new way of opening devices. The ble_serial code goes away entirely, since now libdivecomputer knows about BLE transport natively, and doesn't need to have any serial wrapper around it.
