Contract Primitives and Upgrades to Bitcoin

This post is a mini high level SoK covering basic details of a number of different new proposed primitives that folks might find useful -- I think there's less to discuss around this post, since it is at a higher level and the parts contained here could be discussed separately.

If something isn't on this list, it's an oversight by me and I'd love to add it. The subjective criteria for inclusion/exclusion is if it seems something the community is actively considering and is relatively well researched.
