Errorgroup now works as it used to, using an old-style asBroadcastStream
instead of a proper broadcast controller, because that's what the tests
are testing for.

Analyzer was complaining about code that should have been deleted.
Now it is.

These callbacks will be called when the broadcast stream no longer
has any listeners, or when it gets a listener after having none.

The callback is provided with a StreamSubscription-like object where
it can pause/resume/cancel the underlying subscription on the original
stream.

Change all instances, except some tests, to be sync still.
Rename Multiplex to Broadcast everywhere.

Makes subscriptions the active part of a stream, with the stream
itself being just an inert creator of subscriptions.

This changes the behavior of a "single subscription" stream to match
the documentation: After the subscription is canceled, you can't
resubscribe to the stream. Previously, you could do that, but it was
never documented or intended.
This also makes the stream of a StreamController not be paused while
before it's subscribed - it is always the subscription that is paused
or not, and while there is no subscription, the stream cannot be
paused. Previously the stream was set to paused until the first
subscription in order to prevent events from being lost. That is
handled independently of pauses now.

Adds StreamController.multiplex constructor. This name is tentative,
and likely to change. Its behavior may change as well. It currently
provides a new single-subscription stream each time its "stream"
getter is read, and you can subscribe to these.

Adds StreamIterator class that allows iterating over a stream's data
events using (async) "moveNext()" and "current", like a direct style
Iterator (sorry, it won't work in a for-in loop).

It is the one keeping the buffer of events, not the stream.

This was originally submitted as r17822, and rolled back in r17867. There are no
changes, but in preparation for the dart:io Stream changes we're applying this
with the intent to mark Windows tests as failing.

These changes are still breaking the Windows bots, so I'm rolling them back
until we figure out what's going on.

Apparently StreamController will soon stop extending Stream, so this gets rid of
all uses of it as a Stream in pkg/http and pub.
