A new function was introduced to abstract the setup of input devices for each os: os_SetupInput().
I hope I implemented this everywhere correctly and the behaviour is identical to before.
The new function mcfg_CreateNAOMIJamma() creates the NAOMI Jamma interface and is hidden behind a compile flag (same as before).
The previous function mcfg_CreateDevices() was renamed to mcfg_CreateDevicesFromConfig() because it creates the devices based on the configuration (``nb`` setting).
