Change docs structures to support efficient work processes

To support efficient workflow, we need to produce a document structure that separates generated documents from edited ones, just as classes are separated from source files, and generated sources from edited sources. The target structure will look like this:

                              javase
                                |
                                6
     ___________________________|

 webnotes docs
    | ________ _____|___ ______ _______ ____
    | | | | | | |
 install technotes legal : api platform jre jdk
          _______|_______ : | | |
         | | | : | api api
      tools samples guides : _____|_____ _____
                                : | | | |
                                : jvmti jdwp rmi serialization
                                :

where the api/ and platform/ directories contain normative generated specs, while jre and jdk contain informative generated specs.

Here is what the direcotories will contain:

   docs/api: Java SE apis. (Same as current docs/api)
