dispatch: typed handlers, respond/defer/error, automatic ErrorResponse, watchdog

Browse source 
src/dispatcher.ts routes a directive to capability.on(name | "*"), device.onDirective() or
device.onReportState(), with the payload checked by the descriptor of the interface. The
DirectiveContext answers with respond/report/defer/error; respond() and report() start from
device.state(). A handler or 1.x listener that throws or rejects is answered with INTERNAL_ERROR
(an AlexaError with itself) and reported through "error", never as an unhandled rejection.
Undeclared interface, unknown directive, AdjustMode on an unordered mode and a missing handler
get INVALID_DIRECTIVE, a bad payload INVALID_VALUE; a device with an "Event" or "ReportState"
listener keeps the answer to itself. Every answer passes the dispatcher: the first one per
correlationToken is published, a second is refused. No answer within answerWithinMs (6500,
0 = off, unref'd timer) sends INTERNAL_ERROR and emits "unanswered". A messageId that arrived
in the last 60 s is dropped. New: "unknownEndpoint", options answerUnknownEndpoints, publisher,
timers, and bridge.receive() to run a bridge without a broker. 168 tests pass (18 new).
