build-infra changes have been pushed into jdk8/build

[Kelly O'Hair]

The build-infra changes have been pushed into jdk8/build. Should be integrated into jdk8/jdk8 master repos soon.

Good work guys!

I know there is still more work to do on this, but this is a major milestone, and I wish to extend my appreciation
to everyone that has worked on this, and will be working on it going forward.

I tried to sync the build-infra repositories with the jdk8/build forest and ran into some problems.
Managed to take care of corba, jaxp, jaxws, and jdk.  But the root repo and langtools created some
merge issues. Someone really familiar with langtools should do that one.
The root repo I'll figure out, the configure file is causing my mergetool to go nuts and die, so
I'll need to do the merge with a different merge tool.

I think (not positive) that everyone that has an author name can have JPRT push their changes into jdk8/build forest,
and if so, we could continue our build-infra work via the jdk8/build forest and abandon the build-infra area,
but it's up to you guys. The changesets would need a CR and a reviewer, but I can help with that if need be.
