This is mostly a code move. There is a bit of
boilerplate at the top, and I just use
`assert.deepEqual` instead of `assert_same`.
I also use a little wrapper to provide
output like this:
Starting node tests...
running tests for dispatch_subs
test: add
test: peer add/remove
test: remove
test: update
test: add error handling
test: peer event error handling
One little piece of code that was obsolete
simply got deleted, not moved.
One of the goals here is to un-stub the
stream_data layer.
