Brian Warner 802cfc87fe CLI: allow dispatch functions to return Deferred ...

In addition, CLI functions are allowed to use sys.exit() instead of
always needing to return the exit code as an integer.

runner.py now knows about the blocking httplib calls in scripts/cli and
scripts/magic_folder, and uses deferToThread() to invoke them. Those
functions cannot return a Deferred: when rewrite them to use twisted.web
or treq, we'll remove this deferToThread call.

Option parsing was split out to a separate function for testing. We now
use twisted.internet.task.react() to start the reactor, which required
changing the way runner.py is tested.
