This moves the responsibility for printing skip messages to the engine,
rather than the reporter. Reporters now just need to choose how to
display the messages produced by the engine.

This lays the groundwork for #394, since skip messages can now be
emitted during the run of a test.

This makes it possible for a test to be marked skip based on its runtime
behavior rather than being strictly based on its metadata.

See #393 and #394

The new constraint reflects the actual APIs we're using.

This output was added in a recent dart2js version, and it's redundant
with test's own output. It's also breaking tests.

This is useful internally for Google, and is not considered a public
feature with stability guarantees.

Currently this doesn't support --pub-serve mode. If that becomes
necessary, it can be added later.

These are only intended to be used by Google's internal test runner.
Their API is not public nor is it guaranteed to be stable. They're being
moved into the external repository to ease the pain of merging.

This prepares for https://codereview.chromium.org/1994743003/, which
moves some of these functions into the collection package. Once that
lands, we'll add a follow-up CL to use those APIs from collection.

Review URL: https://codereview.chromium.org//1890853003 .

We were closing hidden tests in Engine.close(), but this isn't
necessary. A test is only hidden if it's complete, complete tests
don't block closing their parent suites, *and* closing the parent suite
will close the test anyway.

Looks like we hadn't run the analyzer against all the top-level
libraries.

We no longer generate a file called runInIsolate.dart, so there's no
reason to fold it out of our stack chains.
