Naming scheme is now:
* ratbag - the context
* ratbag_device - the device
* ratbag_profile
* ratbag_button
...
Only leftovers of "libratbag" are the header file name, #defines that are
exported through that header file and anything that has to do with the actual
library iself (e.g. the symbol export file).
