Clean up IETF module names

Clean up IETF module names

The primary key is the IETF module name, make sure that is reflected in
packaging. The basic idea here is that differing revisions and up
reflecting diffent package names.

This patch allows for differing revisions to exist based on standard
names and the revision -- whereas previously we used the document as a
starting point for the namespace.
