Previously, several commands automatically ran "pub get" implicitly before doing
their work. We've determined that this behavior is confusing, and for "pub run"
in particular, makes the executables seem much slower than they actually are.

This also allows us to make access to the entrypoint's package graph
synchronous.

* Normalize paths before they're passed to dart2js. It handles "." and
  ".." path components poorly.

* Ensure that paths emitted by list-package-dirs are always absolute and
  normalized for backwards-compatibility with the existing protocol.

* Make Package.listFiles work for an in-memory package.

* Fix an error message expectation in packages_file_test.

This allows pub to get rid of the RewriteImportTransformer. This reduces the
runtime of "pub run polymer:new_element --help" by about 270ms.

This shaves off a pretty significant amount of time for packages that are
transformed but whose transformers never change (I saw a ~450ms gain in one of
my tests).

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.

Specifically, when run with "--trace" or "--verbose", pub will capture its stack
chains and report them along with errors. Otherwise it should behave identically
