API Changes and Deprecation List for V4

[cowboyd]

Certain APIs are going to need to change, although not very much, for v4. We should make a list of them.

• call() This is very overused for noting scope, and also for evaluating promise. We are going to deprecate the bare promise
  • add notes on the what is changing about call(), and how to upgrade
  • add scoped() to V3. It will be just an alias to call(). One option for upgrade. Upgrade would involve replace call() -> scope() then fix TS errors.
• Scope#run -> run(op, { scope })
  • ideally replace Scope#run -> Scope#spawn
• action(): Action will become more like the promise constructor and will not take an operation function, but instead will take a simple function that receives a resolver to be called when the effect resolves. It is more a general effect resolver than anything else.
