Remove some not-regenerated files.

Remove some of the files which are in 'src-gen' folders but do not
correspond to anything we generate anymore. They are leftovers from
very old versions.

They were identified using this simple procedure:
1. Remove all the generated files from the working copy:
   % rm -rf src-gen/org
2. Re-generate the content of the directory.
3. Ask Git about which files are now missing, and remove them:
   % git ls-files --deleted | xargs git rm

Remove invalid annotations in generated code.

Remove two obsolete @Deprectated annotations (for types which are not
deprecated in the metamodel) which were responsible for many warnings
in the code base for no good reason.

Also remove an invalid @SuppressWarnings annotation in
ContainerStyleImpl.

This cleans all warnings in org.eclipse.sirius/src-gen.

Use an external reference for the JARs needed to build the doc.

We used to include the required JARs directly inside the "lib"
directory, but the Eclipse rules prevent this so that directory was
removed before submission.

Use the same technique for the EEF bridge as for the same doc: we
assume the use has installed the JARs locally in his HOME folder.
