This also allows us to limit our tests to the latest barback, which
simplifies the necessary infrastructure and speeds up the tests
dramatically.

Once pub gets rid of RewriteTransformer, this will allow it to avoid
passing in assets to Barback unnecessarily.

In particular, this adds CHANGELOG entries for packages that have been
modified and fixes pub's barback dependency so it doesn't declare
compatibility on an uncut release.

This releases args, barback, http_parser, and shelf.

It will be followed up with barback 0.15.0, which will remove support
for Span.

barback 0.14.1 will be added to third_party/pkg in a follow-up CL.

These packages are used in pub's plugin isolate, so pub needs to have
a dependency on them to ensure their APIs don't change out from under
it.

Previously, two transformers from the same library but with different
configuration was considered completely different from one another. This was not
only inefficient but incorrect: it meant that a transformer could be loaded with
the wrong code.

Rather than only looking at the package-level dependency graph, pub will now
examine transformer files' imports to determine dependencies between
transformers. This improves both load times and cycle detection. For example, a
package using polymer transformers can now load them in two phases rather than
four, reducing the load time by about half.

In addition, this gives transformer authors more control over how parallel their
transformer graph is. With some $include/$exclude and import tweaks, most
remaining transformer dependencies can be eliminated.

Transformers that are used in the package that defines them will be loaded in
the same isolate only if they're in the same phase. Otherwise, all transformers
within a given package will be loaded in the same isolate.

A future CL will take more advantage of this by more aggressively determining
when transformers can be safely loaded in parallel.

This level is not printed by default, but will be printed by pub if
--verbose is set.

Also update the observe/polymer version constraints. This change is
backwards-compatible from a transformer implementer's perspective, so the lower
bound doesn't need to be incremented.
