The real pin tests were broken by the new factory stuff. This commit fixes them up, and fixes up a few other bits besides (like why the pigpio PWM tests were failing, why RPi.GPIO sometimes segfaulted on PWM tests, etc.) It also causes the real pin tests to run against MockPin (thanks to @lurch for the suggestion!). This required some tweaks to MockPin to make it emulate physically pulled up pins itself (which in turn necessitated changing quite a few pin numbers in the main test suite because we were using 2 and 3 everywhere), and to allow one MockPin to drive another. Anyway, everything's working now including all the tests on a Pi (haven't tried RPIO yet, but only because I'm on a Pi3 - everything else works with overall coverage of 88% :).
