In kernel, library import URIs now support an "app" scheme as an alternative to the "file" scheme, representing a path relative to the application root. dartk takes an --app-root flag giving the application root. If none is given, file URIs are used instead. The intention is that kernel binaries should not carry irrelevant path information, such as the path to the home directory of the user who compiled a given file. It is not the intention that end-users should see an app URI. Import paths are currently not shown to users at all, and if we need to do this, they should be translated to file paths first. In theory we could stick to file URIs with relative paths, but the Uri class from dart:core makes this difficult, as certain operations on it assume that file paths should be absolute. Source mapping URIs are not yet affected by this change.
