Some of the transport types have meaningful names.
The BLE transport has a device name that was exposed during device
discovery, for example, and some back-ends (ok, right now only the
Aqualung i300C and i770R) need to know what that device name was in
order to handshake with the device properly.
Other transports, like the USBSTORAGE one, could usefully use this to
get the basename of the path to the storage, although right now that
transport makes do with simply doing a "dc_iostream_read()" on the
transport instead.
For now, this is just the infrastructure, ready to get hooked into.
