Changing the folder structure will cause too many broken links for external references (from other sites). So, let's put the content back where it was before the reorg, and instead use the new persona-based navigation to point to documents in the original locations. Also, introduce redirects for some documents that no longer exits. Signed-off-by: David B. Kinder <david.b.kinder@intel.com>
