Léo Lam 256c9375c9 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.
