Revised GPIO module interface + GPIO discovery logic
* The GpioHandler class is no longer a static singleton, rather an
ordinary object with a dynamic guard against multiple instances. This
makes testing/mocking a lot easier and simplifies implementation.
* It uses a basic, mockable udev interface; the module comes with
complete unit testing of the discovery mechanism.
* Corresponding changes to user classes, including UpdateAttempter and
UpdateCheckScheduler.
Note that the implementation of the test mode signaling protocol is
currently a no-op, always returning false, and hence has no effect on
the update process yet. This mechanism will be implemented in a later
CL.
