Lambda repo now supports new build infrastructure

[Mike Duigou]

Hello all;

Maurizio (who had a lot more work to do in this than I did) and I have done another merge into the lambda repo from the jdk8 master repo. Part of this merge is the new build infrastructure. (see <http://openjdk.java.net/projects/build-infra/guide.html> for more info)

A clean build of the entire lambda repo using the new build system is 23 minutes on my wimpy laptop compared to 1 hour 40 minutes with the old build system. Incremental rebuilds are also much, much faster.

We're going to give the lambda repo a chance to settle and bake for a few days at least before generating a new binary build. In the meantime it's now easier (and faster) than ever to generate your own builds!
