JSAutoRequest is required before calling into most JSAPI methods, for GC reasons. Calling it is required and fragile as one must not forget. Further, SM52 and later make manipulating JSContext* dangerous as that can cross Compartment(Realm in SM68) barriers (and ScriptInterface now matches a Compartment). The solution to both problems is to avoid using JSContext* in 0 A.D. itself. To achieve this, a Request class is introduced, and must be used to access a JSContext* from a scriptInterface. Further, Request is passed to other ScriptInterface functions isntead of JSContext*, making it obvious that the caller has already called it, reducing errors and redundant JSAutoRequest calls. Only JSNative functions now get a naked JSContext* without protection, but the likelihood of forgetting a request is lower since many ScriptInterface functions now expect it. JSContext* is directly passed to JSAPI functions only.
