After a lot of do, undo, redo, I sent, this morning, a PR containing a first draft of this split.

To give an idea of the final result, the generated spec doc is available here : https://dl.dropboxusercontent.com/u/2898173/cdi-spec.html

 The goal of this splitting is to have an EJB free version of the spec to provide an official Java SE support for CDI. It’s also the 1st step to introduce parts in the spec, should we decide to do it.

Thanks for your feedback, here, in the pull request or in the corresponding Jira ticket : https://issues.jboss.org/browse/CDI-160
