Introduce a state machine for Bob's secure-join

Browse Source

This introduces a state machine which takes care of managing the
handshake transitions in the secure-join protocol.  This separates
user interactions from the protocol state handling.

This means that while handling the protocol state there are a bunch of
failures no longer possible due to all state information being
guaranteed to be present.  As part of this the QR-code state has been
extracted from the generic Lot structure to something suitable just
for the SecureJoin protocol.

A LogSink has been added to the testing tools allowing log messages to
be correctly displayed on test failures.
