* Add APIs for config and interface descriptors. Split out the common parts of selecting a config descriptor from device desc and selecting a setting descriptor from a config desc. * Parallelize the few tests that actually can be parallelized safely. Add comments where they can't. Note to self: it would be beneficial to restructure the fakelibusb to index all properties of the lib with the used context. That way a libusb implementation wouldn't need to be referred via a shared variable.
