+ Stop running `pub get` at gclient sync time. This was slow and unnecessary.
+ Stop symlinking non-dart_pkg packages into gen/dart-pkg/packages. This suffered from three problems:
   1) These symlinks were not being specified as build output by any rule. They were a magic side effect.
   2) There was a race where many symlinks to the same package could be created, the last one winning.
   3) Related to 2, if two packages relied on two different versions of the same package, we could have hard to reproduce bugs that depend upon the winner of the race.

We now have a checked in copy of all third-party Dart packages needed by the Mojo Dart SDK. These live under //mojo/public/dart/third_party. There is a script 'update_packages.py' which uses `pub get` to handle all version constraints and updates the source tree after pub is run. It's now trivial to ensure we have a compatible set of packages checked into the tree and to update the package set.
