Support more bus types (part 2 of 2). Originally libsensors was very

i2c-centric. Make it more neutral so that we can cleanly support
additional bus types such as SPI or One-Wire.

This second part updates sensors_bus to use sensors_bus_id. Thanks
to Mark M. Hoffman for showing me how the configuration file
parser could be modified to support that change.
