User story: as a Maven plugin developer, I want to be able to define new project packaging types that build Eclipse/OSGi/P2 artifacts and be able to use these projects as dependencies of Tycho projects, i.e. bundles, features, repositories, products, etc.

This will implemented as new extensions interface tentatively called DependencyMetadataProvider

public interface DependencyMetadataProvider {
  public void setupProjects(MavenSession session, 
                            MavenProject project, 
                            ReactorProject reactorProject);
}

DependencyMetadataProvider.setupProjects will be called as part of TargetPlatformResolver.setupProjects to give external Tycho plugins the chance to declare preliminary dependency-only p2 metadata that will be used to establish reactor build order.

Full p2 metadata will be generated by the custom Tycho plugin as part of normal mojo execution and "published" to the reactor p2 metadata (details to be defined).

As a proof of the new API, tycho-source-plugin will be refactored to use the new API and all references to source bundles will be removed from tycho-core, specifically from P2TargetPlatformResolver.setupProjects.
