Add USB passthrough setting and USBUtils This adds a USB passthrough setting to ConfigManager and everything needed for the UI to show and manage the whitelist properly.

Move libusb utilities to LibusbUtils * Simplifies libusb context usage and allows us to set options for all contexts easily. Notably, this lets us enable usbdk support in libusb, which is now opt-in in the latest version. * Moves the libusb config descriptor wrapper class to LibusbUtils too since that could easily be reused. * Moves device listing to LibusbUtils too and add a lock around it as some libusb backends are not thread safe. * Consequences: only a single context and a single event handling thread is used now, which is more efficient.

Use separate libusb contexts to avoid thread safety issues Unfortunately, it appears that using libusb's synchronous transfer API from several threads causes nasty race conditions in event handling and can lead to deadlocks, despite the fact that libusb's synchronous API is documented to be perfectly fine to use from several threads (only the manual polling functionality is supposed to require special precautions). Since usbdk was the only real reason for using a single libusb context and since usbdk (currently) has so many issues with Dolphin, I think dropping support for it in order to fix other backends is acceptable.
