This patch cleans up the use of a few external MSDN links, adds a bunch of constants which were previously undocumented, and reorganizes a table to fit in with those constants. Patch uploaded to http://codereview.appspot.com/969045 for review.
I should also note that the 2.6 and 3.1 commits also exposed the *ReflectionKey documentation. That documentation was added as part of a feature for 2.7/3.2, but those documentation pieces should have been backported on their own but were not.
